Long term cost benefits of polystyrene insulation

 Polystyrene is a highly durable building and insulation material, designed to offer superior, constant insulation performance over their entire service life of more than 50 years.

The exceptional R Value of polystyrene used as insulation maximises your energy savings and level of comfort in your home. The higher the R value, the more effective the insulation is in reducing heat flow in or out of your home. Foamex polystyrene sheets and blocks will not deteriorate with age, delivering constant R values for the life of the building or home.

Using the right type of insulation will help maintain pleasant temperatures, meaning you don’t need to be constantly using heating or cooling devices in your home. The correct polystyrene insulation can save you thousands in reduced energy bills.

Implementing roof insulation, underfloor insulation and wall insulation will help you reduce costs for the lifetime of your home.
