Spray foam insulation has several advantages to other forms of insulation but must be installed correctly to ensure that you produce those benefits. It is important that the chemical components of the expanding foam insulation are at the correct temperature and properly mixed before being sprayed. Adhering to chemical guidelines will improve the spray foam’s performance. If you mix the spray foam’s components at the wrong ratio or incorrect temperature, it may leave cracks or gaps. If installing insulation yourself, be sure to follow instructions precisely to avoid being left with a poorly-insulated home.
