Polyurethane Spray Foam
The US Department of Energy (DOE) studies show that 40% of your home’s energy is lost due to air infiltration.
Without the proper insulation people are just paying to heat or cool the outdoors which is highly inefficient and less environmentally safe.
One particular Insulation product that works extremely well for energy efficiency would be Polyurethane Spray foam. This is a product that is applied through a hose with a spray nozzle that allows the applicator to coat the building envelope.
PSF has an R-value of 6.0 per 1 inch of material applied. This makes it easy to achieve minimum R-values or higher if preferred.
