A Deep Look At Spray Foam Insulation

The most popular kind of spray foam insulation is polyurethane. The development and usage of polyurethane is accredited to the military during the 1940s. During those earlier years it was mostly applied to aircrafts. Polyurethane had to wait until 1970 for it to be utilized as effective foam insulation in households. A variety of systems are deployed in application of spray foam. The “2 part high pressure system” is normally used when it comes to construction of new homes. It is a fast expanding brand of spray foam. The other system is the “2 part low pressure”. This one is normally used in existing walls where remodeling jobs need to be undertaken.

Spray foam insulation is categorized into 2 major categories as explained below;

spray-foam-insulation-open-vs-closedOpen cell:

This is a foam type whereby the tiny cells aren’t closed completely. The cost of open cell foam is less prohibitive due to the fact that it does not contain a lot of chemical ingredients. Although it is very good as an air barrier, it seldom provides any kind of moisture barrier. You’ll also discover that it is more or less like a sponge in physical appearance. Open cell foam is mainly used to insulate interior walls and experts do not recommend it for outdoor application purposes.

Closed cell:

This is a type of spray insulation foam that is pretty dense as compared to the open cell foam. Its cell structure tends to be smaller and more compact. It is a fantastic air as well as moisture barrier. Generally, closed cell foam can be used anywhere but It is normally ideal for roofing projects as well as other outdoor projects.

Spray foam insulation has saved energy costs as well as lowered utility bills in most house holds. The energy department of the United States has carried out a survey which indicates that about 40 percent of a household’s energy gets lost as a result of infiltration of air through the windows, walls and doorways. However, the same cannot be said of homes that have been fixed with spray foam insulation.

Closed cell foam protects buildings from unwanted moisture that can cause growth of mold &mildew. Mold and mildew can cause the wooden frames supporting your house to rot and ultimately collapse. Mold can also be a nuisance to your health as your body can experience allergic reactions courtesy of harmful mold spores.

On top of moisture and temperature controls in many house holds, spray foam insulation can be used to lower noise levels. This is because it acts as a barrier to sounds that are airborne and which are transferred through the floor, walls and roof of a building.

There are federal as well as state tax incentives for home owners who have insulated their homes with spray foam insulation. These incentives are in form of tax deductions. These wonderful tax incentives have encouraged many people to adopt usage of spray foam insulation to treat their buildings.
