Literally a lifetime of experience installing impact windows and doors gives us the right to say when it comes to Storm Windows, we know what we are talking about. Our window replacements are installed by our people who have been trained by the best. We have seen the horrors left by other installers. So many others would agree, you wont ever regret using us to handle your windows and doors. Some of the brand names we use are Jeld-Win, PGT, Eastern Architectural, Therma-Tru to name a few.
Most of todays window frames are either vinyl, or aluminum. Aluminum normally can withstand more pressure than the vinyl. The glass comes in different thicknesses to accommodate the needs of the areas you are in. We try and push Low-e with our window replacements. It is a treatment that allows light through the glass, but protects from the heat. (a must here in SW Florida) Impact windows and non impact windows still have to meet thermal codes.
