Spray foam insulation, sometimes known as polyurethane foam or "foam rubber," is a kind of thermal resistant material that helps to insulate buildings and improve air quality. In order to create an even layer of protection over large areas quickly and easily, polyurethane foam insulation is applied using a spray system.
Spray foam may help you save up to 70% on your heating and cooling expenses when used in conjunction with other insulation strategies such as wallpaper and blown-in insulation. Spray foam insulation pages explain the different types, including open-cell spray foam and closed-cell spray foam, with a higher r-value.
Spray foam insulation became available in the early 1970s. It uses less energy and water than traditional building insulation methods, such as fiberglass and batt insulation. Spray foam insulation is a two-part system. The first part is the thermal core, which contains polyurethane and expands to fill any cavities. The second part is the polyurethane expansionant, which causes the foam to rise and create an airtight seal. Spray foam insulation can be used in conjunction with an air sealing and weatherization system. By reducing the infiltration of wind and rain water into your structure, you may be able to reduce your energy bills. A spray foam installation will also help protect your property from moisture damage that can occur as a result of extreme weather conditions.
Spray foam insulation is less expensive and more energy effective than other types of insulation. For example, batt and roll insulation typically uses fiberglass batts that can be as large as 4' x 8'. These batt insulation can weigh 100 pounds each and take up a lot of space. In comparison, a 2" depth of spray foam using the proper ratio will weight only about 40 pounds per cubic foot and will occupy less than half the volume of traditional batt insulation.
Another alternative is loose-fill insulation, which is made up of small balls of insulation that are typically filled with a polyurethane foam. This type of insulation is less expensive than spray foam, but it can be more difficult to install and may not provide the same level of protection from moisture and heat.
Then there is radiant barrier insulation, which is a type of insulation that uses an aluminum or polyethylene panel to reflect heat back into the room. This type of insulation is usually installed in the attic or roof space and can be more expensive than other types of insulation.
There is no one-size-fits-all answer to this question. The best advice would depend on the climate in your area, the size and type of structure being insulated, and other factors. However, spray foam insulation generally provides an effective way to reduce energy bills and protect against moisture damage in climates that are typically hot and humid. Dallas is extremely hot in summer and can get very cold in winter, so it is important to choose an insulation product that will work well in these conditions.
