Building contractors will find our method ideal for providing the latest Thermal Storage†homes and commercial buildings such as schools or hospitals. Self-builders can live their dream by building with WARMERWALL blocks to enjoy a highly insulated home with year round cosy draught free comfort with whisper quiet interior that will continually reward you with some of the lowest heating costs around. The WARMERWALL blocks made of a building grade flame retardant type of expanded polystyrene are quick and easy to construct, fitting together with a simple tongue and groove design. The blocks interlock to form the walls into which special strong mix of concrete is poured. Once the concrete has cured the wall will have a strength typically four times stronger than a wall built of high density concrete blocks or bricks. There is no need for additional insulation in most cases and the blocks also have unique steel fixing strips embedded into the insulation every 150mm vertically as a fixing method for interior and exterior cladding, cupboards, radiators etc.
