Spray wall insulation is one of the several home insulation options available to you. That is if you have been giving serious considerations to keeping your home warm and at same time considering how to reduce your energy bills. The insulation is often used primarily on residential walls and ceiling cavities.

This insulation is better known as spray foam insulation and as the name suggests it makes use of foam. This foam is liquid, which contains modified urethane or polyurethane (polymers) and foaming substance, which makes it swell to nearly a hundred times its initial volume. This makes it to fill air gaps, removing spaces and cracks that standard fiberglass will not prevent.

This mixture is then sprayed with the help of a device known as spray gun to floor cavities, ceilings or on walls after which it will expand to close up spaces. Then you may have to remove excess foam when the wall has dried.

Spray wall insulation (using foam) can act as air and wind barrier removing the requirement for detailing of individual air tightness which could boost energy efficiency, thereby reducing the number of cooling and heating system equipment that is needed in your home. Moreover, insulation resulting from sprayed foam does not sag, shrink or settle.

Two kinds of foam are used for insulation. That is open cell and closed cell. The open cell allows water and vapor, while the closed cell (polyurethane), which has higher R-Value (this refers to term used in knowing thermal resistance) does not. Therefore, closed cell foam prevents mold formation, which could occur due to high moisture build-up.

Though applying spray wall to your home is considered relatively easy, it still does require someone with skills and knowledge about this. Therefore, to carry this out, it will be good for you to get in touch with companies that offer insulation services. You can do this online by typing "home insulation contractors" on the space provided on the search engine.

This will give you a result made up of business directories, etc. In this result you will have directories that offer you information about different companies in various industries, while you should also come across other directories that only offer information on companies which render only insulation services.

Spray wall insulation is considered to be one of the best ways to prevent heat loss, but also know that this type of insulation has a down side, which is in the hazardous chemicals that may sometimes be used in making the foam. Therefore, it may be better to get a company that offers insulation services to handle this task for you in order to prevent exposure to this type of chemicals.
