PCS Delta Tile Backer Thermal Construction Board

DeltaBoard thermal construction boards, often referred to as tilebacker boards are manufactured using high density rigid extruded polystyrene as its insulation core. The rigid lightweight core has a factory applied reinforced cementitious coating which provides a hard wearing robust surface that is perfect for the application of tiles/plaster and synthetic render. DeltaBoards are produce in a wide range of thickness and sizes. They are used extensively within the construction industry for a wide range of applications such as insulating beneath electrical underfloor heating, as waterproof wall and floor boards for the creation of wetrooms and steamrooms, and for external or damp environments such as basements, garages and conservatories.
