For starters, many windows are built with single-strength glass. Our manufacturer’s windows are built with double-strength glass, which means that each pane is 3 mm thick instead of the industry standard of 2 mm. The glass is stronger, more protective and won’t crack or break as easily. Windows are about 80% glass, so it’s important to select a glass package that will help shield your home from absorbing outside heat in the summer and losing indoor heat in the winter. For optimum energy savings consider our manufacturer’s windows with the ClimaTech® insulated glass package. ClimaTech combines Low-E glass with argon gas† and the Intercept® Warm-Edge Spacer System to achieve optimal energy efficiency. Because our manufacturer offers a variety of ClimaTech glass packages, your window professional can help you choose the best one for your home and area of the country.
