Tilemaster Adhesives Delta Flexi Heat Insulating & Waterproof Construction Board Thickness 20 mm - Short Cut Direction

Tilemaster Adhesives Delta Flexi Heat Insulating & Waterproof Construction Board

Thermal Construction Boards, often referred to as tilebacker boards are manufactured from high density extruded polystyrene. The rigid insulating core is coated with a specially formulated reinforced cementitious coating that provides a hard wearing robust surface perfect for the application of tiles/plaster and synthetic render.

The foam core has excellent thermal insulation properties whilst also providing high compressive strength with very low weight. The cement coating enhances the fire resistant properties of the board and creates a tile ready surface. The cement based coating also gives the product excellent impact resistance, ensuring that the boards stand up to the rigour of the site environment.

Available in: Thickness 20 mm - Long cut direction & Thickness 20 mm - Short cut direction
