By now, everyone knows the importance of insulation. Insulation provides protection from temperature variations, saves money on heating/cooling bills and can add value to homes. What people often miss is that some insulation is greener than others. Extruded Polystyrene is a versatile rigid insulation with high R-values and a lifespan that far outstrip those of its competitors.

The versatility of Foamular's rigid insulation board design means it can be used almost anywhere. It can be used as garage insulation, insulation for basements, roof insulation membranes and under slab insulation. The applications are unlimited.

Foamular is produced using an environmentally friendly HCFC blowing agent in complete accordance with United Nation Protocols regarding CFCs. By reducing CFCs Foamular is helping to preserve the Ozone Layer and protect the environment

The lightweight design of Foamular means it saves on transport costs. With a lighter load, transportation vehicles require less fuel and contribute less to greenhouse gasses.

Foamular has incredibly high R-values in comparison to other materials.

Foamular XPS 250 /50mm =R1.78

Expanded polystyrene 50mm, m grade = R1.20

Brickwork, 110mm = R0.18

Weather boards, 12 mm avg, pine = R0.08

Concrete slab, 2400kg/m3, 100mm = R0.069

Plaster board, 10mm = R0.059

Fibre cement sheet, 6mm = R0.019

This high R-value means that over the life of Foamular, it gives better thermal protection, reducing heating and cooling bills for its entire life. Foamular is guaranteed to maintain at least 90% of its R-value for its useful life.
