We live in Dallas. Our large front windows face west. Is there any new window product that will make the rooms shady and keep out the heat in summer? We have sun screens but all the manufactures say if we reattached the screens to their replacement windows it voids the warranty. We are looking at about $13,000 to replace the front windows and want the best we can get to block the sun and heat. Winters are not a problem here. -Janette
Windows have come a long way in recent years and are now able to deflect much of the sunlight in the summer while at the same time retaining the heat inside your home during the winter. One of the biggest advancements has been in low-E coatings, which can be ordered on many windows these days. These almost invisible films of metallic oxide are applied to one or more surfaces of the glass during manufacture and can markedly reduce the amount of sunlight and heat that enters or leaves your home.
For even more protection, you can combine a low-E coating with tinted glass. Be sure to discuss your options with the window manufacturer in advance so they can make specific recommendations to fit your situation.
