Spray foam is made from polyurethane. Spray foam prevents air leakage, and it is better than any other foam of insulation in the market. Most buildings have cavities especially buildings that are unusually shaped, and spray foam is used to cover up the building. The general contractor is in a position to provide professional services as far as spray foam and roofing are concerned.

Types of spray foam insulation

gffgfggfgfgffgggfThe market has two types of spray foam insulation; open-cell spray foam and closed-cell spray foam. The denser the spray foam, the greater the R-Value of the insulation. Closed cell spray foam has the upper density of the two spray foam insulators.

Ingredients

The ingredients used to make spray foam are mixed using a particular equipment that is attached to a trailer or truck. A mixing gun sprays the substances on the area that needs to be insulated. Heated hoses are used to transport the chemicals to the mixing gun. A chemical reaction (exothermic) starts once the chemicals are mixed; the liquid mixture then foams thus expanding and eventually hardening.

Disposable cans

For a small job or a small part of a building, one can buy the disposable cans of the foam spray and use it at the particular place that is needed. The little boxes are sold in various sizes and have a broad range of prices that suit ones need and requirements.

Open-cell spray foam

The open cell spray foam has a low density and is vapor porous. It is used to create a conditioned attic that is un-vented in a cold climate. A vapor retarder covers the interior face of the foam. Thus, the cured foam is sprayed with the vapor retreading paint. The blowing agent of an of open cell spray foam is carbon dioxide or water. Bio-based raw materials like soybean oils are used in the foam of open cell spray foam; the bio based products are used in place of petrochemicals. The open cell spray foam builds an air barrier that is very effective. Free spray foam has a lower R-value compared to the closed cell spray foam. Open cell spray foam also holds water and is vapor permeable.
