Schlüter-KERDI-BOARD-N  Niche set

Niches and storage surfaces for wall areas of all kinds are both convenient and stylish. Our prefabricated elements made of KERDI-BOARD make it a simple task to install such niches. They can even be integrated into the Schlüter-KERDI waterproofing system as a bonded waterproofing assembly.

What's more, you are getting pre-fabricated sets, but they offer enormous freedom of design – thanks to four different dimensions and the option to variably integrate rectangular formats and intermediate shelves.

General product information

What this product does

Schlüter-KERDI-BOARD-N are prefabricated installation components for creating niches and shelves for wall areas of all kinds, made from the multi-functional tile underlayment Schlüter-KERDI-BOARD. They can be covered directly with tiles or with suitable rendered/plaster covering materials.

How to install this product

Schlüter-KERDI-BOARD-N

Installation in Schlüter-KERDI-BOARD:

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

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

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

Installation in plasterboard or other panelling:

  1. After positioning and precise marking of the outer niche dimensions, cut the corresponding opening in the wall covering.
  2. Attach the inserted niche with wood or installation screws, depending on the material of the substructure. The maximum spacing of screws is 250 mm. Set the screws through the niche flanges (spacing approx. 6 mm from the outer edge).

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

  3. Wall areas located in high-moisture areas must be waterproofed with Schlüter-KERDI. Adhere the supplied KERDI waterproofing collar on the flanges of the niche with KERDI-COLL-L. A suitable tile adhesive can be used for the remainder of the wall area (see product data sheet 8.1 for notes on installing Schlüter-KERDI). Then cut the KERDI membrane in the area of the niche insert.

Important:

The following installation notes must be observed when using niches with additional adjustable shelves:

Start by marking the desired position along the lower edge of the adjustable shelf.

Fully embed the tiles in the front and lateral areas of the niche with tile adhesive. To install the adjustable shelf, apply tile adhesive on the sides and rear of the shelf and fit them into the niche so they are supported by the previously installed tiles.

Recommendation: For installations in wetrooms, install the adjustable shelf with a slight slope toward the front. As an alternative, you can install the tiles at a slight slope. This ensures that no water can accumulate in the niche during use.

Waterproofing with Schlüter-KERDI-BOARD-N

In accordance with the German waterproofing standard DIN 18534, Schlüter-KERDI-BOARD-N can be used in water exposure classes W0-I bis W3-I*. Furthermore, Schlüter-KERDI-BOARD-N features the national technical approval (abP) required in Germany.

Moisture load class according to ZDB: 0 to B0, as well as A and C.

KERDI-BOARD-N features European Technical Approval (ETA) pursuant to ETAG 022 (watertight covering kits) and bears a CE mark.

* With abP and/or based on ETA according to ETAG 022.

System-certified tile adhesives must be used in areas that require CE-compliance or assemblies according to abP (certificate of technical approval).

Please contact our Technical Department for further information on the use and installation of system-certified tile adhesives or to request the corresponding test certificates and approvals (see also product data sheet 12.1 Schlüter-KERDI-BOARD).

What this product is made from

Schlüter-KERDI-BOARD-N is a panel made of extruded rigid XPS foam with a thickness of 12.5 mm, which is laminated with a special, cement-free reinforcement material and a fleece fabric on both sides for effective anchoring of cementitious tile adhesives or rendered covering materials. The upper face of the board is imprinted with 10 x 10 mm gridlines.

Material properties and areas of application

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

KERDI-BOARD-N is completely level and will not warp in response to temperature and moisture fluctuations on one side. The material is age-resistant and highly durable.

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

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

How to look after this product

Store KERDI-BOARD on a flat surface or in another suitable form. When stored outside, the product must be protected against direct sun exposure and weather.
