When building, or even remodeling a home, deciding on what type of insulation to use can be difficult. There are so many choices of insulation to choose from.

One type is called closed cell foam insulation. This is a widely used spray-on formula. Many professional builders use it and it is sprayed on by companies who specialize in using closed cell foam. Some people do decide to spray on closed cell foam on their own as well.

There are numerous advantages to using closed cell foam as an insulator, instead of open-cell foam insulation. Due to the closed cell nature, it allows for a thinner layer of insulation to be used.

Despite the thinness, it has R-values of 5 to 8 per inch. An R-value is the measure of thermal resistance found in a structure. The higher the number, the more effective the insulating material is.

A 1 inch layer of closed cell foam provides the same amount of insulation as 2 inches of open cell foam. The superior insulating capability of closed cell foam reduces heating and cooling costs by up to 50 percent.

This will lengthen the life of heaters and air conditioners, due to them not having to work so hard. The heating and cooling efficiency of closed cell foam insulation has a rating in the 90s as opposed to other insulation types which have ratings in the 30s and 40s.

Closed cell foam insulation is non-porous so a vapor barrier is formed by using it. These barriers are usually required by building codes, not matter what type of insulation is used.

Not only is this polyurethane resistant to water vapor, but also to water wicking. This vapor barrier will not promote growth of mold or mildew; it also meets and exceeds all building codes.

This extremely strong foam insulation actually reinforces the surface it insulates, making the structural strength doubly strong. There isn't any trimming required after the insulation is placed, so there is little or no waste.

Excellent sound control is another feature of closed cell foam, plus it can be used in combination with fiber glass. Some mortgage companies actually offer a discount for using closed cell foam insulation when building or remodeling.

It is important to consider foam insulation cost and see if do it yourself foam insulation is a better alternative for you.
