“If you compare EPS side-by-side with some foam plastic insulation materials right after they are manufactured, the other materials may have a higher R-Value,” said de Campos. “But EPS is stable and does not experience any thermal drift and does not lose R-Value over its life. In the long run, the thermal performance of EPS insulation is constant, and when all cost and performance factors are considered, it typically provides the greatest insulating value available.”

ThermoBlok insulation is not only used in new construction. Because it is ideal for after-construction retrofitting, ThermoBlok Dealers can go after the even larger, almost unlimited, renovation market.
The vast majority of homes - estimated at over 90% - have inadequate insulation. This means the majority of owners are unnecessarily paying far too much for energy. ThermoBlok insulation is the solution to this waste.
