Schlüter-KERDI-BOARD offers versatile, lightweight and waterproof tile backerboard option

As one of the most versatile and widely specified products from Schlüter-Systems, Schluter-KERDI-BOARD finds applications for both retrofit and new-build installations, with different thicknesses of the extruded polystyrene (XPS) panel providing a stable and waterproof substrate for natural stone and ceramic tiling.

The panels are available in thicknesses of 5, 9, 12.5, 19, 28, 38 and 50mm and are easily installed across existing masonry, concrete, timber stud frames or lightweight metal framing, with panels featuring parallel grooves also available for creating rounded surfaces, such as for seating or curved walls.  With all thicknesses available in 1.25 m or 2.6 m lengths, both by 62.5 cm wide, KERDI-BOARD is frequently used to create work-surfaces, breakfast bars, islands and vanities. 

A handy guide can be downloaded from the Schlüter-Systems website which can assist both specifiers and tradespeople in picking the right panel for an application. For instance, 12.5 mm is the minimum thickness recommended for use where a stud frame is constructed to 400 mm centres.  The largest three thicknesses should be considered for construction purposes, while there are also special L-shaped and U-shaped panels for use as pipe boxing, and prefabricated niches in different sizes – with or without lighting – to create storage within walls. 

Both sides of the KERDI-BOARD panels have a waterproof, cement-free reinforcement layer, which offers an ideal surface for standard tile adhesive, either fully embedded or using the dot and dab method. Printed lines aid accurate cutting using a utility knife or power tools.
