Insulation Board Fixing Washers provide a simple and secure solution for fixing insulation and tile backer boards to floors and walls, including Thermopanel, Marmox and Wedi-type boards.
Featuring a countersunk design, the washers allow the screw head to recess into the board while the outer rim remains flush with the surface, providing a neat and secure finish.
The perforated washer surface maximises board surface exposure, allowing adhesives and plasters to bond effectively to the board and helping to reduce the risk of surface delamination or damage.
