Does Drew Foam EPS require large amounts of resources to be produced?
No, studies have shown that EPS foam and insulation production uses one-third the energy to produce than paperboard, half the atmospheric emissions and 42% of the water wastes, compared with paperboard products. Also, total EPS rigid insulation production uses less than 0.1% of this country’s petroleum, making it both low cost and environmentally friendly.
How effective is EPS insulation?
EPS insulation and EPS rigid foam insulation have been proven to be extremely effective as insulators. Thermal performance is measured in terms of resistance to the flow of heat. This thermal resistance is expressed in R-values, the higher the number, the better the insulation. The R-value of the most commonly used Class (Class SL) is 1.13 for every 50mm thickness. Thus, 44mm of this Class of EPS delivers an R-value of + 1.0.
Does age affect the thermal performance of EPS?
No. EPS consists of 98% air and 2% polystyrene. Because of its cellular structure EPS is stable, and installed correctly does not deteriorate over time and is able to deliver constant R-values for the life of the building.
Does EPS contain CFCs?
No. EPS is chlorofluorocarbon (CFC) and hydro chlorofluorocarbon (HCFC) free. At no point during the manufacture or application of EPS is the use of CFCs or HCFCs, or other compounds which are said to contribute to the degradation of the ozone layer, needed.
