SanteQ Lightweight Walling

Features and benefits


Together with the permanent formwork and concrete infill, the cured weight of the entire system is between 550kg per m3 and 1350kg per m3 depending on non-loadbearing or loadbearing applications. This represents a weight reduction of up to than 75% 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 similar sound insulation to traditional brick and mortar.
