FAQ

The easiest way is to use our configurator. A technical clarification is then made directly here and all further processes are mapped automatically. However, our configurator cannot map all applications. You are therefore also welcome to send us your order by email. Please use the corresponding order and inquiry form.

Immediately after sending the order, you will receive an automatically generated order confirmation with all technical, design and legal information. Within 48 hours, we will then technically check your order confirmation and send you a detailed order confirmation by e-mail. If you requested a CAD drawing during the order process, you will also receive this with the order confirmation. After receiving the order confirmation you have 24 hours to check it. If we do not receive any feedback within these 24 hours, we will start to integrate your order into the production process. Changes or cancellations are then basically no longer possible. A written release of your order confirmation is only required if you have selected this in the configurator or if your order confirmation contains a corresponding release field.

After the order has now been integrated into the production process, you will not hear anything further from us for the time being until the planned completion. If there are unforeseeable production delays in individual cases, we will proactively inform you in good time. As soon as your order has been released by our quality assurance department, you will automatically receive a message about the completion of your order and the information that it will now be promptly handed over to our logistics partner.

As soon as the goods have left our shipping department, we will send you the invoice by e-mail with the corresponding payment deadline. Shortly thereafter, our logistics partner will contact you to arrange a joint appointment with you. The delivery of our sliding doors is always carried out by Hermes Einrichtungs-Service in 2-man handling.

The delivery time of our individually manufactured sliding doors is not clear at first glance due to the many material combinations. Therefore, we have compiled a detailed list of delivery times to provide you with this information as early as possible during your planning process.

Download: Overview Production and Delivery Times (PDF)

In addition, during the configuration process, the delivery time will be automatically calculated for you according to your product selection and listed in the summary. After receiving your order, we will schedule the production process and send you the planned delivery week upon receiving the order confirmation.



If you need your product earlier than specified, please feel free to contact us.

Accessories which cannot be pre-assembled by us, such as loose brush seals, fastening material, etc., are well packed in the upper guide rail. Therefore, there is usually no separate box for accessories. Sliding doors ordered without filling material (e.g. BAUSATZ collection) are delivered disassembled. But here, too, all profiles are already precisely cut and provided with the necessary holes/punches.

We pre-assemble almost all components at the factory. Please check the top of the sliding door leaf for bottom-running systems. The soft stop automatic is located here centrally on the sliding door leaf
.


For top run end systems, please check if it is directly behind the trolleys in the rail

Our products are packaged using the On Demand Packaging® process. We almost completely avoid the use of plastics in our shipping packaging. On Demand Packaging® eliminates the need for pre-made, off-the-shelf cartons that do not fit. Proper sizing reduces material consumption and does not require the use of plastics, Styrofoam or the like to fill empty spaces. You can therefore recycle our shipping packaging free of charge and sustainably via the waste paper recycling process.

Of course. Simply click on "Pickup" in the delivery type in the check out and secure 5% additional discount. Please note that the goods will then be provided unpacked with only an edge protection for collection.

Unfortunately, there is no general answer to this question and it depends on many factors. We would like to make the assembly as simple and uncomplicated as possible for you and already pre-assemble almost all components (rollers, stoppers, rails, etc.).

Sliding doors with infill material are of course delivered pre-assembled at the factory. Sliding doors without or prepared for on-site filling material (collection BAUSATZ) are delivered disassembled. But here too, all profiles are already precisely cut to size and provided with the necessary drill holes/punch holes.

How elaborate the assembly is in the end, however, depends among other things also on the condition of the building substance. We offer already for a small additional price, appropriate fastening material. Alternatively, you can of course also use your own fastening material.

Further information: assembly instructions bottom-running system (PDF) | assembly instructions top-running system (PDF)

Here, too, we cannot give a blanket answer. The duration of the installation basically depends on the size of the sliding door system and the condition of the building structure.

Further information: assembly instructions bottom-running system (PDF) | assembly instructions top-running system (PDF)

You will basically need professional assembly tools. Your standard equipment should include the following: Metre rule, rolling rule, spirit level, Allen key, hammer, cordless screwdriver, various bits and drills. Bits and drill bits. However, you may need more specialized tools due to the nature of the structure.

More information: assembly instructions bottom-running system (PDF) | assembly instructions top-running system (PDF)

No, not really. As a rule, the familiar fastening materials such as screws, nylon dowels, etc. are sufficient. In individual cases, it may be advisable to use a mounting adhesive suitable for the substrate for further fastening. However, you should check this in each individual case.

If you have selected "jamb" as the opening in the configurator, we automatically include special adapters for attaching the guide rail to a sloping roof. These brackets are already pre-assembled at the factory and only need to be adjusted to the appropriate angle of the roof slope. In addition, 2 clip holders are supplied with each adapter. These brackets can later be used to attach the on-site fascia above the guide rail.

In the case of ceiling and integrated ceiling mounting, the rails are basically symmetrical. However, we mark rails and brackets with "front side". Please mount rails and brackets according to these specifications.

The question is not very easy to answer. Since our system is suitable for a wide range of installation situations, the answer can be very specific and related to the application. First of all, it is important for us to convey that the decision for our system does not end in a dead end. Our modular rail system usually always finds a solution and allows us and our customers a high degree of design freedom and planning security. Simply send us an e-mail with your requirement. Our customer service will be happy to combine all necessary components and materials and provide you with a technically clarified offer.

That depends entirely on how meaningful and extensive the inquiry is. Basically, we always have to read your request technically and evaluate it for us. As a rule, we answer inquiries that reach us by 12 noon on the same day. Requests we receive in the afternoon will be answered until 12 o'clock the following day. In any case, we get back to you promptly, even if we still have questions. Basically you can say, the more concrete and shorter a request is, the faster we answer. Key points in combination with a small hand sketch or a photo are therefore often sufficient for us to be able to process the request.

We do not have a printed price list. Our sliding doors are always configured individually. This is usually done via our online configurator. If the planned sliding door system does not work via the configurator, we will be happy to check what is technically feasible. Therefore, please send us a message with all necessary information to our customer service. Supporting you can also use our [inquiry form].

Spare parts as well as individual assemblies and samples can be calculated and ordered directly via our Articleshop.

Do you need individual spare parts for an existing sliding door? You can find these in the Individual Parts section.

The part numbers of the spare parts can be found on the technical data sheet of the respective system in the Technical Compendium.

You have your own ideas in the implementation and want to choose from different hardware sets and rails? For this we have already compiled appropriate assembly articles.

Yes, there is a measurement guide. Simply download it here, print it out and enter the data in the configurator. Alternatively, you can also send us an inquiry by e-mail. For this purpose, please use our inquiry form.

Our sliding doors are always made exactly to measure in millimeter increments. A min. and max. dimension can not be named as a general rule. We can produce very high and wide sliding doors with low weight. Everything that our configurator offers is technically feasible for the time being. However, our configurator only covers a small part of the technical possibilities. For example, we can also produce honeycomb panel sliding doors up to 2000 mm wide and 4000 mm high.

If the desired size in the configurator is not feasible, you should not immediately despair. Download our Download inquiry form (PDF) and send your inquiry by e-mail to service@kuhn-schiebetueren.de. We will check what is technically feasible and provide you with a solution proposal in a timely manner.

It depends on the size and material selection. We will provide the exact weight of the sliding door system with our order confirmation. To obtain this information in advance, the following rule of thumb can be used:

Aluminum frame sliding doors:
DECOR, FUNCTION, WOOD collection: 5.6 kg/m²
GLASS collection: 15 kg/m² (6 mm glass thickness), 20 kg/m² (8 mm glass thickness)
Collection LACK: 7.2 kg/m²
STONE collection: 9.4 kg/m²

All-glass sliding doors:
GLASS collection: 20 kg/m² (8 mm glass thickness), 25 kg/m² (10 mm glass thickness)

Honeycomb panel sliding doors:
DECOR, FUNCTION, WOOD collection: 19.8 kg/m²
Collection LACQUER: 22,8 kg/m²
STONE collection: 26.4 kg/m²

We will be happy to check. Our customer service will usually always find a solution. All we need is the fully completed measurement sheet. Please send this to our customer service department by e-mail. We recommend the following aids for determining the dimensions: Meter stick or tape measure (alternatively length laser), spirit level
.
Tip: For your smartphones, there are now also very good and free apps such as Magicplan Download: iOS | Google Play

We will gladly send you free samples of our profiles and surfaces. The samples as well as shipping and return shipping are completely free of charge for you. As a rule, you may keep the samples for 6 weeks for viewing. If you want to keep the samples longer than 6 weeks or even permanently, this is of course also possible. Simply note this in the additional field when ordering. We will then contact you about your request.

If none of the filling materials we offer appeals to you, or if you are looking for a special filling material, please feel free to contact us via e-mail or phone.

Width: Measure the finished plastered opening from wall or reveal left to right in 3 places (top/middle/bottom) and enter the smallest dimension in the configurator.

Height: Measure from the finished plastered ceiling or lintel to the top of the finished floor (OKFF) in 3 places (left/center/right) and enter the least dimension in the configurator.

Caution: If you find dimensional deviations of more than 5 mm, we need further information from you. To tell us these, please use our measurement sheet.
.
We will then calculate the exact dimension and adjust the rail lengths according to your specifications. For arrangements between Two walls, we recommend to adjust the rail lengths according to the determined dimensions above and below. In order to place the rails between the walls without any problems, we also recommend to order them 3 mm shorter. You can adjust the exact dimension of the rail in the configuration process. If this is too uncertain for you, you can also order the rails 100 mm longer and shorten them on site.

We will be happy to arrange a consultation appointment with you.

Each product in our system family was developed for a specific application. Therefore, it is also possible to use different systems in one project without any problems. We never leave our innovative basic design. We therefore always have the right system for your application.

A complete overview of all systems can be found in the respective section on our website:
Aluminum-frames-sliding-doors | Honeycomb-panel-sliding-doors | All-glass sliding doors.

This is handled by our algorithm in the Configurator.

Very many. Almost everything is possible and almost nothing is impossible. To plan with our products, you should already have an idea of what is important to you or what features your new sliding door solution should fulfill. If you are still completely unsure and you feel "overwhelmed" by the possibilities with our products, we understand.

Direction and wrong do not exist here either. However, our experience has formed a clear opinion. Everything that has more than 2 rails should be designed as a bottom-running system.

Why do we recommend this? This is mainly because bottom-running systems basically run without play in the rail.

Top-running systems must already be equipped with an accompanying paddle driver in the case of 2-running arrangements. This then ensures that the 1st wing is carried along in the 2nd wing. Works first so far but depending on the wing width and number of wings, the sliding door system then gets relatively much play.

Achtung: A suction in the building (eg by opening a door) can then lead to the fact that the sliding door wings swing stronger or weaker.

This works very well. Our modular rail system can be used for the following installation variants:

Wall mounting
ceiling mounting
integrated ceiling mounting

Our rail system has a height of 60 mm. The width is based on the respective rail combination. The reasonable combinable variants can be found in the respective sections.

Tip: If you are not yet sure whether you want to use a bottom-running or top-running system, you can also install in advance only the base profile in the intended ceiling recess.

You can then decide at a later date which variant you would like to use. Also, whether you want to use an aluminum frame, all-glass or honeycomb panel sliding door system, you can decide at a later time after installing the base rail. The entire system is based on each other and can be combined with each other. This offers you a maximum of planning security and design variety.

Yes, this works. The following possibilities show up:

You have the option of a top-running system without the base profile. The height of the running rail is then only 32 mm. An overview of the possibilities can be found in the technology compendium.

You use a bottom-running system with 48 mm rail height. This is our Eco system. A high-quality system which but price offers the entry into our product world.

You still use the base rail with 60 mm and let this protrude slightly from the suspended ceiling.

We generally recommend installing the upper guide rail straight and finishing the gap between the rail and ceiling/ lintel with acrylic. Glazing blocks are very helpful for leveling the ceiling rail. However, these are not part of the scope of delivery.

If the course of the ceiling deviates very much from left to right, you can also use one of our stick-on glazing bar profiles to cover the gap.

Each of our frame systems has been developed for a specific application. Goods have profiles that not only provide a visual finish to the filling material, but also offer added functional value in the application.

Basically, it can be said that frame profiles with integrated stop seal are very suitable for use between two walls and in front of and against a wall.

The sash then forms a clean and almost tight closure to the wall by means of integrated stop seal.

In addition, the continuous handle strip forms a high ease of use. The opposite is the case when we place doors running in front of the wall. The handle strip is then covered by the wall on one side. We do not recommend frame systems with integrated handle strip then for this application.

Frameless systems but also systems with a narrow aluminum frame, where then additionally in the surface a handle is placed, are much better suited for this application.

We can write and explain a lot here, we have already prepared good content on our website in the section Alurahmen-Schiebetüren.

Possible handle options can be found on our website under the heading handles.

We distinguish between the Eco series 48 mm view and Pro series 60 mm view. Our Eco series is an entry-level product from our product world in terms of price.

Our series Pro can simply depict almost everything and is the absolute professional range in our portfolio.

Many of our market competitors have successively expanded their range over time and usually created individual "island solutions". We have a fully modular system, which in itself forms a self-contained unit.

Everything is possible, everything can be combined with each other in a meaningful way. This makes our Pro series not only flexible to use, but also particularly sustainable.

Like Tetris. But with no losers!

At KUHN, we are pursuing a new holistic approach to solutions and for the first time are uniting the application areas of ìbuilding and furniture sliding door hardwareî in terms of both design and system technology. Our concept envisages that despite the numerous installation situations, hardware connections and profile geometries, the innovative basic design is never abandoned.

We offer our rail profiles in 2 different heights. Here we distinguish as follows:

Series Eco = 48 mm / Series Pro = 60 mm

The width of the rails is determined by the exact system configuration.

An overview of all useful rail combinations can be found in our Technology Compendium (PDF)

For more information: Lower System Assemblies (PDF) | Upper System Assemblies (PDF)

Please check in advance whether the room in which the sliding door system is to be installed has underfloor heating. In this case, we recommend that the bottom track (whether surface-mounted or recessed) is simply glued to the floor covering or screed. Our recessed tracks are fixed to the screed surface and our surface mounted tracks are fixed to the finished floor. However, dimensions always refer to the upper edge of the finished floor (OKFF). What exactly does OKFF mean? Upper edge of finished floor.

Achtung! Please never give us the dimension without finished floor.
.
In principle, however, our running rails are suitable for almost all types of flooring.

The following options are available for selection:

Unclip skirting and allow door leaf to ride up to wall/leaf. Use one of our 3 different plinth leveling profiles. Alternatively, we also offer an adjustable wall leveler. The complete overview of these profiles can be found at the following link:

For more information: Data Sheet Additional Profiles (PDF)

Attention! When measuring, please make sure that despite the skirting board on the floor, the dimension is measured from wall/leaf left to wall/leaf right. The configurator automatically adjusts the sash width when using a base or wall compensation profile.
.
It is important that you adjust the bottom rail length according to the smaller width (between the skirting boards) in the configuration process.

Some of our systems do not require additional handles.

This applies to the following systems AR20, AR30, AR30B, AR30F and WP30. For all other systems, they are in the configuration process corresponding handles to choose from. It is also possible to deselect the handles.

We then manufacture the sliding doors without handles and recesses. Our handles are basically available in the corresponding profile colors silver, platinum white, black and alpine white. Special colors and finishes are basically available upon request.

For aluminum frame and all-glass sliding doors, we also offer polished hole drilling in the glass on request. You can determine the diameter and arrangement yourself.

If none of our handle variants appeals to you and you would like to use a specific handle, please send us an inquiry with a picture of the desired handle variant. If technically possible, we will then be happy to offer you the desired variant.

A complete overview of our handle variants can be found on our website under the heading handles.

Caution: We do not offer handle cutouts to customer specifications for individual sliding door installations. We also do not pre-assemble handles provided by the customer at the factory. If it is a project with several sliding door systems, there is the possibility to realize customer-specific wishes..

Unless otherwise specified, our handles are arranged at a height of 1050 mm. This dimension refers to the upper edge of the finished floor (OKFF) to the center of the handle. Unless otherwise specified, the edge distance is 70 mm from the outer edge of the sash to the center of the handle.

This dimension is based on the sash projection of 30 mm on the wall surface. If you want a larger sash projection, you should also place the handle accordingly further on the surface.

Ex. The sash has a sash projection of 30 mm on the wall in the standard configuration process. The handle is arranged by the configurator with 70 mm distance. However, you now want a sash projection of 80 mm. In this case, the handle should be adjusted to 120 mm distance.

You should provide us with this information when making an inquiry or placing an order.

The height of the handle can be freely selected on request and thus placed higher or lower. The lateral arrangement can be larger 70 mm but not smaller.

This is mainly related to the fact that the handle must not be placed too close to the edge area due to a risk of glass breakage.

A complete overview of our handle variants can be found on our website under the heading handles.

This depends entirely on which floor covering is present. Our surface-mounted running rails are already delivered with a corresponding (strongly adhesive) tape. In addition, this can then be fixed with a mounting adhesive approved for the floor covering, depending on the substrate. Our recessed running rails are usually glued in place with the appropriate adhesive for the floor covering. This can be, for example, a tile, parquet, carpet or vinyl flooring adhesive.

Basically, you should make sure that the adhesive shows good compatibility with the materials used and is solvent-free.

Caution: Please make sure that the substrate is free of dust and grease.
.
We assume no liability for the compatibility of the adhesive with the corresponding materials!

Some of our systems do not require additional handles. For all other systems, you have the option to deselect them in the configuration process under the menu item Equipment - Handles. We then manufacture the sliding doors without handles and recesses.

Caution: For individual sliding door systems, we do not offer handle cutouts according to customer specifications. We also do not pre-assemble handles provided by the customer at the factory. If it is a project with several sliding door systems, there is the possibility to realize customer-specific wishes..

This option is available only with our aluminum frame sliding doors. We offer infill dividing muntins in horizontal arrangement. The fields can then be equipped with different materials and thicknesses. The following material thicknesses can be used: 4, 6, 8 and 10 mm
.
If you also want to divide the sliding door panels vertically, this is also possible on request.

Our collections include over 200 different filling materials. Here we distinguish between different materials such as wood and glass materials. These materials are divided into the following collections:

DECOR
FUNCTION
GLASS
WOOD
PAINT
STONE
CONSTRUCTION

Not all filling materials are also available for all systems. For better classification, we have prepared a corresponding overview. If none of the filling materials we recommend appeals to you, or if you would like a special filling material, please feel free to contact us.

The filling dimension is automatically calculated in the configurator and listed in the summary. In addition, we also transmit the filling dimension in the order confirmation which is sent to you approx. 48 hours after receipt of the order receipt mail. The calculation of the filling dimension can also be determined on the respective technical data sheet of the system.

Caution: There are different formulas for calculating the filling dimensions. Therefore, choose the appropriate data sheet for your system in the technical compendium before..

Aluminum frame sliding doors can be divided with muntin profiles. Basically, we distinguish between surface-mounted and infill-dividing muntins. Depending on the selection of the corresponding frame system, we offer different muntin widths. These usually correspond to the face width of the upright frame profiles. Such as AR30 (30 mm profile view, 30 mm muntin width. Glazing bars can be arranged both horizontally and vertically. However, the configurator currently allows only a horizontal one. If you want a vertical muntin arrangement, please feel free to contact us.

The following combinations are possible:

Rung attached 10 mm:
AR10, AR10S

Rung attached and fill-splitting 25 mm:
AR20 Eco

Rung attached and fill-splitting 30 mm:
AR30, AR30B

No glazing bars are available for the systems listed here:
AR02F, AR30F, GG00, WP00, WP02, WP30

The selection options of the muntin variants are automatically filtered in the configurator. Only what is technically possible can be selected.

Further information: Technikkompendium Einzelteile (PDF)

No problem, many of our customers install the filling material themselves. We then deliver the sashes disassembled. However, all components are already precisely cut and pre-drilled. We also pre-assemble the majority of the fittings. This means little effort on the part of the customer.

To order this version, simply configure your sliding door system completely and then select the appropriate material thickness under the menu item "Fillings" in the collection "BAUSATZ". We will then deliver the wings pre-prepared according to your desired material thickness.

You will receive the filling dimension in the summary of your configuration and additionally after technical inspection by our customer service with receipt of the order confirmation.

The following material thicknesses are possible:

Aluminum frame sliding doors
4 mm, 6 mm, 8 mm, 10 mm (10 mm, only with wood materials)

All-glass sliding doors
8 mm, 10 mm

Honeycomb panel sliding doors
21-38 mm (means you choose within this thickness itself).

This option is only available on request and for larger quantities.

Attention: We assume no liability for filling material provided by the customer.

The possibilities are dependent on the selection of the system.

The following material thicknesses are possible:

Aluminum frame sliding doors
4 mm, 6 mm, 8 mm, 10 mm (10 mm, only with wood materials)

All-glass sliding doors
8 mm, 10 mm

Honeycomb panel sliding doors
21 - 38 mm (means you choose within this thickness itself)

There is no right or wrong here. However, our experience has formed a clear opinion. Everything that has more than 2 rails should be designed as a bottom-running system.

Why do we recommend this?

This is mainly because bottom-running systems basically run without play in the rail. Top-running systems must already be equipped with an accompanying sash driver in the case of 2-track arrangements. This then ensures that the 1st sash is carried along in the 2nd sash. Works first so far but depending on the wing width and number of wings the sliding door system then gets relatively much play.

Caution: A suction in the building (eg by opening a door) can then lead to the fact that the sliding door wings swing stronger or weaker.

We asked ourselves: What can we do without? Our system can be adapted in function and form to any individual requirement, whether as a carcass unattached furniture application, passage door, room divider, partition or as a complete room-in-room solution. Our systems are therefore durable, functional, timeless, stable and maintenance-free.

Aluminum frame sliding doors are particularly light and can be used for large sash dimensions. In combination with infill dividing transoms, aluminum frame sliding doors can be equipped with different infill materials. The circumferential frame forms a practical closure to the filling material and usually takes over not only the sealing to the wall, but also the operation of the wing. Overall, it can be said that aluminum frame sliding doors are suitable for almost any application.

Which different aluminum frame systems we offer and what advantages are associated with them, you can find on our website under the heading Alurahmen-Schiebetüren.

All-glass sliding doors are made of a full-surface pane and usually do not have a surrounding frame. We process both single-pane and laminated safety glass in a wide range of designs and properties. Since the edge of the glass is visible, it is polished and given a small phase.

For more information, please visit our website at All-glass-sliding-doors.

Honeycomb panel sliding doors are made of 38 mm thick wooden material construction. The outer layers are each 8 mm thick. The inner core is constructed from a 22 mm thick, very stable honeycomb. In the edge area we process an approx. 50 mm wide bar made of multi-layer birch wood all around. In addition, depending on the width, several aluminum rectangular tubes are inserted in the inner part of the honeycomb and connected to the outer cover layers. Due to this technical structure, our honeycomb panel sliding doors, in conjunction with appropriate additional equipment, have good sound insulation properties, high stability and a sash weight that, despite its good properties, has a balanced weight.

You can find out which different frame systems we offer and the advantages associated with them on our website under the heading Honeycomb-panel-sliding-doors.

It depends on the size and material selection. We will automatically provide you with the exact weight of the sliding door system upon receipt of the order confirmation. To obtain this information in advance, the following rule of thumb can be used:

Aluminum frame sliding doors:
DECOR, FUNCTION, WOOD collection: 5.6 kg/m²
GLASS collection: 15 kg/m² (6 mm glass thickness), 20 kg/m² (8 mm glass thickness)
Collection LACK: 7.2 kg/m²
STONE collection: 9.4 kg/m²

All-glass sliding doors:
GLASS collection: 20 kg/m² (8 mm glass thickness), 25 kg/m² (10 mm glass thickness)

Honeycomb panel sliding doors:
DECOR, FUNCTION, WOOD collection: 19.8 kg/m²
Collection LACQUER: 22,8 kg/m²
STONE collection: 26.4 kg/m²

All sliding doors with infill material we deliver pre-assembled. So if you order a sliding door with 2 wings from us, you will receive a total of 3 packages. 2 packages for the respective wings and 1 package for running and guide rails. Accessories that cannot be pre-assembled by us, such as loose brush seals, fastening material, etc., are placed in the upper guide rail. Therefore, there is usually no separate box for accessories
.
Sliding doors ordered without filling material (BAUSATZ collection) are delivered disassembled. But even here, all profiles are already precisely cut and provided with the necessary holes / punching. Accessories, which can already be pre-assembled by us in the factory, we also mount.

This works only with aluminum frame sliding doors and filling dividing muntins. But then almost everything is possible here. Not only can different materials be used, but also different material thicknesses such as 4, 6, 8 and 10 mm. However, not all filling materials are available for all systems. We have therefore prepared a corresponding material overview. These filling materials are also assigned to the systems in the configurator according to this overview.

Our collection includes over 200 different materials, colors and surfaces. Depending on the system, these can be used both fully but also combined with each other.

Yes, there are. However, not all filling materials are available for all systems. We have therefore prepared a corresponding overview. These filling materials are also assigned to the systems in the configurator according to this overview.

If none of the filling materials we recommend appeals to you, or if you would like a special filling material, please feel free to contact us.

Either you order the sliding door system without filling, pre-prepared for your material thickness or you tell us the desired material.

Due to the variety of different configuration options and systems, we offer this additional equipment only on request.

Please send us a picture or a sketch of the installation situation here in LiveChat or by e-mail with the relevant details such as the design of the locking mechanism (WC, PZ etc.) and whether the locking mechanism is to be designed on both sides (inside and outside).

We offer our soft stop automatic (also called softclose or damping) as additional equipment. A minimum sash width of 760 mm is required for this. If the sash has a smaller width, it is still possible to use an automatic soft stop under certain conditions.

That's difficult to answer across the board. We have a real bestseller with our AR30 aluminum frame sliding door system that actually always fits, but it may well be that another frame profile is better suited specifically for your application.

Each of our frame systems has been developed for a specific application. Our range includes frame profiles that not only provide a visual finish to the filling material, but also offer added functional value in the application.

Basically, it can be said that frame profiles with integrated stop seal are very suitable for use between two walls as well as in front of and against a wall.

The sash then forms a clean and almost tight seal to the wall by means of integrated stop seal.

In addition, the continuous handle strip forms a high ease of use. The opposite is the case when we place doors running in front of the wall. The handle strip is then covered by the wall on one side and this makes these systems largely unusable for this application.

For these applications, we have within the system family frameless systems but also systems with a narrow aluminum frame, where then additionally a handle is placed on the surface in the range.

The number of packages depends on the quantity of door leaves and designs of your sliding door system. We deliver all sliding doors with infill material pre-assembled. So if you order a sliding door with 2 leaves from us, you will receive a total of 3 packages. 2 packages for the respective wings and 1 package for running and guide rails. Accessories that cannot be pre-assembled by us, such as loose brush seals, fastening material, etc., are placed in the upper guide rail. Therefore, there is usually no separate box for accessories. Sliding doors ordered without filling material (BAUSATZ collection) are delivered disassembled. But even here, all profiles are already precisely cut and provided with the necessary holes/punches. Accessories that can already be pre-assembled by us at the factory, we also assemble.

For more information, please visit our website under the heading Shipping.

Please document the damage with a picture and contact us immediately via email or by phone.

There is an order label on the package with all the information we need for further assignment and processing.

We will then check the extent of the damage and will promptly come to you with a solution proposal. Please do not assemble the damaged item and leave it in its original packaging.

Please check in advance whether the item has already been preassembled or whether it is a loose accessory in the upper guide rail. As a rule, we pre-assemble almost all accessory components, e.g. soft-stop automatic, carriage, stopper, etc. In the case of bottom-running systems, the running and guide rails are packed together. This is not visible at first sight. In many cases, we already deliver top tracks and guide rails as well as the corresponding accessories in advance. Therefore, check whether the accessories have already been received in advance.
