Looking for Expanded Polystyrene Insulation?

Expanded polystyrene insulation is typically used in flooring applications, below concrete slabs where thermal efficiency (U-value) requirement of the construction is with the limits of the product. Our best seller is currently 50 mm - 2400x1200mm, the depth and thickness of the insulation is there to satisfy the current building regulations and U-value requirements. Polystyrene is one of the most popular variants and can be used where a basic level of additional thermal insulation is required. As an insulator, polystyrene can withstand extremes in temperature and is even a noise reducer. 

Expanded polystyrene insulation is less dense and more affordable than many other forms of polystyrene insulation. It is formed out of pockets that air filled with air, making it a poor conductor of heat, but an outstanding convector. It traps the air in small pockets, blocking the flow of heat energy, this reduces both conduction and convection which makes it an ideal insulator. It doesn’t support mould or mildew growth and it is completely recyclable which assists with LEED points.
