Delta Board is a multi-purpose lightweight construction board, designed for the application of all tile types, cement based screeds, synthetic renders.

They are manufactured using high density extruded polystyrene which provides excellent insulating properties.

The extruded polystyrene core has a factory applied reinforced cement coating which provided excellent impact strength, sound reduction and fire resistance making them ideal for construction.

Delta Board is easy to use and can be fixed using cement based tile adhesives solvent based or ready mixed adhesives must not be used.

Alternatively, Delta Board can be fixed using dowels and washers.

Delta Board enhances underfloor heating systems by reducing downward heat loss.

Delta Board is resistant to water making them ideal for use in areas subject to prolonged or permanent water immersion.
