How They Work

Sealing & Insulation Products

Air leaks and under-insulated areas in a home can lead to wasted energy and higher heating and cooling costs. Weatherization is the process of protecting a home from outside elements like moisture, cold air in winter and hot, humid air in summer and is most often accomplished by air sealing and insulation upgrades that can result in energy savings up to 45%. Air sealing, the process of locating and closing off the gaps, cracks and open seams in homes and is one of the best ways to improve a home’s comfort, health and energy efficiency.
