subject: Spray Wall Insulation For A Warmer Home [print this page] 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.
Also known as spray foam insulation, this type of insulation works by making use of foam. The foam; a liquid actually contains polymer such as polyurethane or modified urethane, and a foaming substance that makes it swell to almost a 100 times its original volume once this is applied. Consequently, as it swells it very well fill air gaps, getting rid of spaces and cracks, which standard fiberglass insulation cannot prevent.
The mixture of polymer with the foaming substance is sprayed making use of a spray gun on floor cavities, walls or ceilings, where it will swell to seal spaces. After which you might need to cut off excess foam after the wall has dried.
Spray wall insulation with foam might also act as air and wind barrier, getting rid of the need for detailing of individual air tightness that may boost energy efficiency, thereby reducing the number of devices required in the home. Spray foam insulation also does not shrink, settle or sag.
Two types of foam are primarily used to carry out the insulation, which is closed cell foam and open cell foam. The closed cell foam (polyurethane) has R-Value (term for thermal resistance) that is higher than that of open cell and is non-porous, while the other is not. Closed cell is good for preventing formation of mold that may occur from the build-up of excessive moisture.
The application of spray wall insulation is not a task that is difficult, but requires the knowledge of someone who is skilled in doing this. Consequently, to get it done, you should visit search engines to check out companies that offer insulation services. You can do this by typing "home insulation contractors" on the space provided by the search engine to begin your search.
The result that you will end up with will most likely be some business directories and others that are related. Some directories have a database for general businesses including installation companies; while others will specifically have a database for companies that offer only insulation services.
Although spray wall insulation may be considered good in preventing heat loss, it is necessary to inform you that some hazardous chemicals are sometimes used in making foam. That is why it may be better to engage a company that offers insulation services.
