Colthurst Farm is fully wrapped in open cell foam insulation! We think it is important for our clients to understand what goes in behind the walls because a well insulated home will provide the highest level of comfort as well as lower energy bills for the owners. We spray open cell foam throughout the entire home, including the attic rafters. Spray foam insulation is a leading high performance insulation material, offering one of the highest R-value per inch of any of the major insulation materials on the market. Specifically, open cell foam expands to 5 times its original size filling in all the crevices and crannies between studs minimizing energy loss. It is often the parts of the home you will not see every day that provides comfort you will feel every day.
