When weatherizing existing homes and new commercial construction, spray polyurethane foam insulation is one of the most effective ways to keep buildings warm in the winter and cool in the summer. Foam insulation is used to fill gaps, cracks, and other problem areas that lead to heat loss. It air seals and insulates, making it easy to fix these heat loss problems along with keeping unwanted bugs and animals out. Not only is foam insulation one of the most effective ways to weather-proof your home, but it’s also one of the most cost effective ways and helps save on energy bills. Insulating your home could qualify you for utility rebates, tax credits and green certification.
