Spray Foam On Attic Floor

The attic is much warmer than outdoors in winter but significantly cooler than the living space if you leave the old insulation in the attic floor.
Spray foam on attic floor. That gives you the chance to maximize your energy bill savings. But now the attic isn t vented to outdoors. Spray foam insulation is a great product. I ve been in plenty of these homes and can tell you that when spray foam is installed properly they outperform 99 of fiberglass batt insulated stick built homes.
This means installing spray foam to a depth of at least 2 on the entire attic floor to completely seal everything up. A cost effective way to use foam insulation is to foam the lid of the house then use loose fill insulation on top. Homes insulated with it can be some of the most efficient and comfortable homes built. After the foam is cured loose fill fiberglass or cellulose insulation gets installed on top of the foam.
I can also tell you that 73 of all statistics are made up on the spot so please don t ask for. The best part of using foam it green spray foam on an attic floor is you only need 1 inch cured thickness to seal the living spaces you use from the attic. Install the spray foam to meet or exceed code required r values or add additional loose fill or batt fibrous insulation over the 1 inch of spray foam insulation to levels that meet or exceed the current adopted building energy codes. That makes the surface of the spray foam cooler possibly even below the dew point.
Spray foam can prove something of double edged sword where costs are concerned according to rlc engineering. Install a minimum of 1 inch of spray foam insulation over the attic floor to provide a continuous air control layer.
