Functionality: Space-saving elegance for every room

The fundamental advantage of sliding doors lies in their space-saving function. In contrast to conventional doors, which require a swivelling range, sliding doors glide elegantly along a track, regardless of whether they run in front of or inside the wall. This makes them ideal for rooms with limited space, such as small flats or narrow corridors. This practical functionality not only enables efficient utilisation of space, but also gives the room a modern and minimalist appearance.

Sliding door in the wall or in front of the wall?

When it comes to choosing the right sliding door, you have to decide between a sliding door in the wall or in front of the wall. Both options offer a modern and space-saving design, but there are some key differences that should be considered before making a purchase.

The in-wall sliding door is an elegant solution where the door slides into the wall pocket, integrating seamlessly into the wall. This not only creates an aesthetically pleasing look, but also maximises the available space. This option is particularly suitable for small rooms where a minimalist aesthetic and a harmonious sense of space are desired.

If flexibility and ease of installation are preferred, the sliding door in front of the wall could be the right choice. These doors are mounted on the wall and can therefore be installed without extensive structural measures. They also offer the option of integrating lockable mechanisms to ensure privacy and security. Perfectly suited for rooms where additional privacy is required, such as bedrooms or bathrooms.

Material and design: individuality in interior design

The choice of material plays a central role in the design of sliding doors. Wood decors radiate warmth and naturalness, while glass lends a modern and transparent touch. The use of plain decors, on the other hand, enables contemporary designs and individuality. The design options range from classic to contemporary, allowing harmonious integration or targeted accentuation depending on individual taste and furnishing style.

Installation, maintenance and areas of application

Practical considerations are decisive when deciding in favour of sliding doors. They are usually fitted using a sliding mechanism, which makes installation easier. Regular maintenance is uncomplicated and sliding doors are durable. Their diverse areas of application range from room partitioning and the design of passageways to space-saving solutions for walk-in storerooms or pantries.

Detailed instructions on maintenance and installation can be found in our installation instructions.
