Why do you use spray foam insulation?
The basics on the open cell foam are the product itself is used to create an envelope in the home. It has a reduced air flow and heat reduction aspect that tightens up the house for efficiency. Because the attic itself is included in the envelope, the attic air is circulated with the conditioned air and, therefore, the attic space tends to be about 10 degrees higher or lower in temperature than the living space. This allows the A/C system and duct work that is stored in the attic to also remain cooler. Because of that, the A/C system tends to be smaller as well,” said Sarah Day-Voight with USI Inc.
