TREL KS stands for Korpu-System. It is a modular assembly kit system for the installation of alcoves in drywalls.

The different modular sizes of the TREL KS system make it possible to utilize all possible storage spaces. Thus individual furnishing dreams can be realized time saving and economically.

After the perfectly fitting installation of TREL KS elements, these can be styled creatively. Colourful accents, glass elements or indirect lightning provide individual designs. TREL KS is multiply applicable as high-quality storage or presentation space for example as cabinet or bookshelf but also as inset ceiling or design element. Typical fields of application are the top floor (jamb wall), bathroom and media walls, in which electrical installations can be covered stylishly.

TREL KS can be combined with the TREL RS system for fitted cupboards.

TREL KS clamp and screws

TREL KS is based on a gapless thought-out system, in which each element and working step are well coordinated. Thus it is possible to minimise time exposure and costs and guarantee high quality, precision and durability at the same time.

TREL KS consists of composite wood based elements (with pilot holes and milling grooves) and clamps. 

Times in which alcoves have been a real challenge and missing standards provided qualitative lacks andClose-up view TREL KS element calculative risks are over.

TREL KS upgrades simple drywalls quickly to alcoves, cabinets, wall endings or frameless bays. 

The TREL KS elements are available in different standard sizes and can be combined modularly. Thus there are multiple fields of application. In addition, there are the possibilities by using self shortened sizes.

Put TREL KS elements togetherInstall back of drywallFixate Korpu at the wall profiles and stabilise it

For the technically correct installation two packaging units, each consisting of two TREL KS elements, have to be screwed together. Afterwards a drywall back is cut out and assembled.

With the help of the clamps the put together Korpu is installed between two 75 mm C-profiles. Until the final fixation the Korpu stays steplessly adjustable. The horizontal side of the Korpu is stabilised by the clamps and pieces of C-profiles. The wall part is planked afterwards. As the Korpu is led by the grooves along the C-profiles there is automatically the ideal space for a simple planking with a 12,5 mm drywall. The professional blending from wood based element to drywall is done by a linking band. The band is put into the milling groove of the front edges and filled. Crack formation and warp is impossible when processed technically correct. Sufficient hard material makes edge protection unnecessary. Clean and stable edges, precise blending and smooth surfaces, are easily and quickly accomplished.

After the installation the TREL KS elements can be styled creatively.

TREL KS standard sizes

TREL KS is available in two standard installation depths (180 mm and 350 mm). The different installation lengths are 200 mm, 400 mm, 600 mm, 800 mm, 1000 mm, 1200 mm, 1400 mm and 2000 mm.

The vertical internal dimensions are each reduced by twice the material thickness of 19 mm. The horizontal internal dimension stays the same.

Example: vertical element 1000 mm, horizontal element 1000 mm, internal dimension Korpu 962 mm high, 1000 mm wide.

As a standard it is possible to process TREL KS alcoves to cabinets by glass shelves and glass doors.

Glass shelves are available for 200 mm, 400 mm, 600 mm, 800 mm and 1000 mm wide Korpu alcoves of 180 mm and 350 mm standard depths. 

Corresponding to this there are six different glass doors for TREL KS alcoves available.

The single doors for of 400 mm, 600 mm, 800 mm and 1000 mm high alcoves fit into a Korpu of 400 mm width. 

For 800 mm wide Korpu alcoves there have to be ordered two glass doors. TREL Korpu with glass elements

Two additional glass doors are applicable for 800 mm high and 200 mm wide and 600 mm high and 600 mm wide alcoves.

A compatible two-door cabinet lock is available. 

Paintable wood-based and décor doors (standard nut tree, beech, white) are available for 400 mm, 600 mm and 800 mm high and 400 mm or 600 mm wide TREL KS elements. For 800 mm and 1200 mm alcoves two doors have to be ordered.
