Why is Sprayed Polyurethane Foam Best?
Heat transfer resistance (“R” value) is a common standard of insulation performance. Polyurethane foam is far more effective than any other commercially-available insulation material in resisting heat transfer. This means that an inch of polyurethane will do the same insulating job as several inches of most other materials. But that’s only part of the story. Sprayed polyurethane foam has other characteristics that make it an even better insulator. • Sprayed polyurethane foam forms a seamless insulating barrier which prevents incursion of outside air, a major source of heat loss. • Properly protected polyurethane foam is relatively immune from water incursion, which can seriously degrade the effectiveness of insulation. • Polyurethane foam won’t sag, buckle, pack down or mat, conditions that reduce insulation effectiveness. • Sprayed polyurethane foam is light and strong. It actually supports itself! Polyurethane foam normally provides more heat transfer resistance with less weight than
