According to the Energy Information Administration, the windows and doors in the average residence are responsible for up to one third of its total heating and cooling losses. In commercial buildings, the numbers are even worse. Up to 40 percent of your heating and cooling energy escapes through the windows in a commercial facility. This increased loss is often due to the abundance of windows installed in businesses including storefronts, restaurants and offices.
If possible, replacing all of your windows with energy-efficient insulated windows will certainly help reduce your overall HVAC expenses due to heating and cooling loss. However, if your home- or building-improvement budget is stretched thin, there’s a more cost-effective solution to curb your structure’s window-related energy losses.
Consider having low-emissivity (low-e) window film installed on the windows of your house, condo or commercial facility. Insulated window film will increase your interior comfort while lowering your overall energy costs. Read on to learn more about the installation and performance of low-e window films.
