SanteQ Lightweight Walling

Features and benefits


Together with the prefabricated cellulose-fibre formwork and the high impact, moulded inserts that make up the entire system, the cured weight is between 550 and 600kg per m3 including skim plaster and paint. This represents a weight reduction of more than 70% when compared to traditional masonry materials, offering distinct design and engineering benefits.


We use non-flammable boards and all components are tested to withstand fire for 2 hours. The system does not give off toxic gases.

Thermal insulation and energy savings

The infill material is comprised of recycled polystyrene which acts as insulation that reduces heat transfer through the walls. When one considers that 25% of the energy loss is through the walls, the savings on heating and cooling are obvious.


Sound insulation

Due to the air trapped in the lightweight infill, the SanteQ walling system offers 2 to 3 times the sound insulation of a traditional wall.
