Spray Foam

Why Foam? - A Better Thermal Insulation

It is important to understand how your building or home wastes energy and what type of action can be taken to correct this problem. Generally heat is transferred from inside a building to the outside in all directions (side to side, up and down). Heat does not rise; hot air rises because of relative densities. Heat energy generally moves from hotter to colder; or more simply, heat follows cold. That means the building, as a system, must be insulated from all sides. Building contractors focus their efforts on insulating walls and ceilings, leaving floors and basement walls completely uninsulated.

R - value is the most common measure of the insulating qualities maintained by an insulation material; it is a measure of thermal resistance. A greater R value will result in more effective insulation. It is, however, important to note that a manufacturer’s R - value applies only to properly installed insulation. Improperly installed insulation is far less effective. Conventional fiberglass batt and blown-in insulation systems may actually perform at a much lower level than indicated by their R – value, depending on how well they have been installed.

The R - value of insulation is substantially diminished with the presence of air leakage. Often, over 40% of a home’s heat loss can be attributed to air leakage.

By using spray foam insulation, installed by a certified DOW styro foam SPF CA installer, the issue of air leakage is eliminated. Spray foam insulation seals your home completely, making it 100% airtight. Spray foam insulation is seamless, making it more efficient than any other material used to insulate a structure. The R – value of medium density spray foam insulation is well over two times that of conventional fiberglass batt insulation, provided the latter is operating under ideal conditions. Medium density spray foam insulation has the highest R - value per inch of any insulation available.

Spray foam insulation, installed by a certified Full Span professional, will maintain it’s stated R - value for the life of the Building, guaranteed!
