Schlüter-KERDI-BOARD-N Niche set

Niches and storage surfaces for wall areas of all kinds are both convenient and stylish. Our pre-fabricated elements in KERDI-BOARD make installing such niches a simple task. They can even be integrated into the Schlüter-KERDI waterproofing system to act as bonded waterproofing.

And although these are ready-made sets, they offer plenty of design freedom – thanks to four different dimensions and the option of fitting rectangular formats and intermediate shelves as you wish.

Function

What this product does

Schlüter-KERDI-BOARD-N are pre-fabricated elements for creating niches and shelves in wall areas of all kinds, made from the multi-functional Schlüter-KERDI-BOARD tile substrate. They can be covered directly with tiles using the thin-bed method or with suitable rendered or plaster coverings.

Installation

How to install this product

Schlüter-KERDI-BOARD-N

Installation in Schlüter-KERDI-BOARD:

After positioning and precise marking of the outer niche dimensions, cut out the appropriate opening in the wall panelling.
Fix the inserted niche in place with wood or installation screws, depending on the substrate material. The maximum spacing of the screws is 250 mm. Use KERDI-BOARD-ZT retaining washers. Screws must be set into the abutting joints.

For additional fastening, the adhesive Schlüter-KERDI-FIX can be applied on the inside flange of the niche.

If the material is installed in a wetroom, the joints around the outer edge must be covered using Schlüter-KERDI-COLL-L and the supplied KERDI waterproofing collar.

Installation in plasterboard or other panelling:

After positioning and precise marking of the outer niche dimensions, cut out the appropriate opening in the wall panelling.
Fix the inserted niche in place with wood or installation screws, depending on the substrate material. The maximum spacing of screws is 250 mm. Place the screws through the niche flanges (spacing approx. 6 mm from the external edge).

For additional fastening, KERDI-FIX adhesive can be applied on the inside of the niche flange.

Walls in wetroom areas must be waterproofed with Schlüter-KERDI. Affix the KERDI waterproofing collar supplied onto the flanges of the niche with KERDI-COLL-L. A hydraulically setting thin-bed mortar can be used for the remainder of the wall area (see product data sheet 8.1 for installing Schlüter-KERDI). Finally, cut out the KERDI membrane in the area of the niche cavity.

Waterproofing with Schlüter-KERDI-BOARD-N

In conjunction with the materials KERDI or KERDI-BOARD and the matching KERDI-KEBA, installers can create certified bonded waterproofing assemblies.Schlüter waterproofing systems have been granted German technical approval (allgemeine bauaufsichtliche Prüfzeugnisse, abP) and European Technical Assessment (ETA). KERDI-BOARD-N is a component of these waterproofing systems and can be installed in accordance with the DIN 18534 waterproofing standard.Where work must be CE-compliant or in accordance with the certificate of technical approval (abP), only system-certified thin-bed mortar should be used.Please contact our Technical Department for further information on use and installation for the designation of system-certified thin-bed mortars or to request the corresponding test certificates and approvals (see also product data sheet 12.1 Schlüter-KERDI-BOARD).

Material

What this product is made from

Schlüter-KERDI-BOARD-N is a 12.5-mm thick panel of extruded rigid XPS foam, its two surfaces covered with a special, cement-free stiffening material and a fleece fabric for effective anchoring of thin-bed mortars or rendered covering materials. One surface of the board is printed with 10 x 10 mm gridlines.

Material properties and areas of application

KERDI-BOARD-N is waterproof and resistant to the chemical stresses that typically occur in conjunction with tiled coverings. Where required, certified bonded waterproofing can be created in conjunction with Schlüter-KERDI or KERDI-BOARD.

KERDI-BOARD-N is completely flat and even when exposed to temperature or moisture fluctuations on one side remains free of deformation, age-resistant and highly stable.

KERDI-BOARD-N is suitable for a wide variety of applications.

Substrates should be checked for sufficient stability and other project-related requirements.

Anodised aluminium: Thanks to the anodising, the aluminium features a refined finish that retains an unchanging appearance during normal use.

Aluminium is sensitive to alkaline media.

Cementitious materials, in conjunction with moisture, become alkaline. Depending on the concentration and length of exposure, this may result in corrosion (aluminium hydroxide formation).

For this reason, remove mortar or grouting material immediately from all visible areas and do not cover freshly laid coverings with foil.
