Polyurethane spray foam insulation is a popular choice for homeowners because of how easy it is to use. Traditional insulation is usually made of fibreglass particles which can be very difficult to apply because of the necessary safety precautions to make sure you don't inhale or touch the fibreglass particles. Polyurethane spray foam insulation goes on as a foam and dries as a solid insulation; however, this form of insulation can be hazardous to your health.
