Homes in the United States are mostly insulated for little to no heat dissipation in the winter and for keeping cool in the summer. This principle is applied to other aspects of the home including windows and doors and there’s a good reason for doing so. Did you know that the average home loses up to 30% of heating and cooling energy through windows and doors alone? It’s for this reason that window manufacturers started numerous projects, launching energy-efficient windows into the market. That’s also one reason why homeowners opt for more energy efficient iterations when they get a window replacement.
