Spray Foam Insulation Blows Energy Loss Away

Spray foam insulation goes a long way in making one’s dwelling an energy efficient space. Having an energy efficient home will make it more comfortable to live in and less costly to maintain. There are a variety of methods for insulating a home in order to achieve this.
In order to keep costs down and proper temperatures within the walls, there are four considerations to ponder. They are 1) the insulation, 2) ventilation, 3) moisture control and 4) air sealing. It is important to have the proper balance between these four.

Insulation creates a barrier or envelope to keep inside temperatures at a certain level. It provides a level of resistance to energy loss from a house. The amount of efficiency is rated in terms of R-values, which means resistance to heat flow. The material, its density, thickness and number of layers will all determine its R-value. Spray foam insulation is a product that is made from a polyurethane composition, which is blown into attic and wall spaces via a specialized reverse vacuum machine. Other types of insulation include blankets, which are often made of fiberglass or rock wool, loose fill, which is usually comprised of fiber or pellets and rigid formed sheets.

Ventilation refers to movement of air through the home and attic. It’s very important to have ventilation within a building so that the temperatures are distributed uniformly. Fans can help with this. Not only will the temperatures be more balanced with proper ventilation, but it will alleviate concentration of pollutants in the environment, as well.

Moisture control is important, too, because the amount of moisture affects temperature regulation. Air sealing refers to closing and caulking up leaks and gaps in windows, around doorways and electrical plates. Heat slipping through the cracks can play a large part in big bills and fuel inefficiency.

If it’s a very small job, a Do-it-yourselfer might try insulating with spray foam by him or herself. The best method would be to shoot it into the spaces in walls and attics between framing studs. The material typically expands way beyond its original volume so easily fills in all gaps and cracks. It even gets more effective over time because as the house contracts and expands, the foam will follow suit. It’s always a good idea to try out the technique in a very small space in order to master the concept of its expansion. Once it’s been sprayed in the area evenly, it should be allowed to settle; then leveled so that it’s even with the woodwork. If the job is large, however, it would probably be wise to hire a professional.
