SUNTEX works with local window manufacturers in the area to help you update your windows with the best quality materials available. If your home is more than 10 years old, itâs likely that your windows are a single-pane or double-pane of glass, with little to no solar UV protection. While this will seal your home, youâre missing out on tons of cost savings in terms of modern window technology which could help you keep your home cooler in the summer, and trap heat inside during the winter â saving you money on your energy bill overall.
