It Works in the Winter too!

As a company that sells and installs solar window films the winter usually is full of commercial,decorative and automotive projects, with the residential client only if they realize that you still get UV and fading in the winter and even when it is cloudy, but you also lose heat through the windows during the winter. Windows and doors contribute up to 30 percent of heat loss and gain in a home, by direct conduction through the glass and via air leakage through the window assembly.[2] The US Department of Energy (DOE) estimates that heat loss and gain through today’s windows account for approximately 4 percent of total domestic energy consumption.[3] Efficiency strategies vary widely based on regional climate considerations: windows can account for 25 percent of of a typical home’s heating energy load in cooler climates, and as much as 50 percent of the cooling load for homes in warmer climates.[4] Windows cover between 10 and 25 percent of the exterior surface area in new homes and selecting windows designed to either retain or repel heat is an important aspect of a whole-house energy efficiency plan. The DOE advocates reducing the environmental emissions from heating and cooling systems—some 150 million tons of CO2 alone annually—from 20-50 percent. Typical kwh saved per day with our Enerlogic $3.87-$4.18 so at 30-31 days on the energy bill that would save 115.00-130.00 per month!
