What is Spray Foam?
Polyurethane the most common type of spray foam insulation was developed and used by the military in the 1940s and applied to airplanes. It wasn’t until the 1970s that it started to be used as foam insulation. Various systems are used to apply the spray foam. The two-component high-pressure system is generally used in new home construction. It is a quick expanding type of spray foam. The two-component low-pressure spray foam is another system that is used primarily for remodel jobs where there are existing walls with drywall already in place. This is also known as a slow rise formula and often referred to as injection foam.
Why is it so good (Benefits)?
Spray foam insulation saves on energy costs and lowers utility bills. Studies by government agencies show that 40% of a home's energy is lost as the result of air infiltration through walls, windows, and doorways. Buildings treated with spray foam insulation typically insulate as much as 50% better than traditional insulation products. Insulation that is sprayed in buildings protects against moisture, which provides the benefit of reducing the chance of harmful mold and mildew addition to building temperature and moisture control, spray foam insulation is often used to reduce noise Foam insulation serves as a barrier to airborne sounds and reduces airborne sound transfer through a building's roof, floor, and walls.
With spray foam, you can lower construction costs, meet or exceed today’s stringent building code requirements, and provide your customers with the benefits of spray foam...

What is R-Value?
R-value is the term given to thermal resistance to heat flow. The higher the R-value of an insulation product, the more effective the insulation properties. 1.8-2 pound polyurethane foam has the highest R-value of readily available insulation used in homes and buildings. Polyurethane is a closed-cell foam insulation material that contains a low-conductivity gas in its cells. As a result of the high thermal resistance of the gas, spray polyurethane insulation typically has an R-value around R-6 to R-7 per inch. Source: Wikipedia.
