Replacement Window Installations in Danbury

There are MANY reasons why a homeowner would want new windows and doors, but the most obvious ones are fairly self-evident. A set of new doors provides a cost-effective way to update your home’s exteriors, thereby increasing value and adding curb appeal.

It’s also energy-efficient, as new windows and doors will keep your conditioned air from seeping outdoors and making it easier for your HVAC to keep your indoor temperatures consistent. In Danbury, All-Pro Windows is the company to call when you want to breathe new life into your Connecticut home.

We also offer the following products designed to improve your quality of life as well as the energy efficiency of your home:

  • Heat Mirror™ by Southwall Technologies  - This revolutionary product by Southwall Technologies employs nanoscale coatings of metal that reflect heat back to its source, hence the name “Heat Mirror”. This results in superior insulating performance that lowers your energy costs while increasing comfort, superior shading in the summer from the sun’s rays which offsets your cooling costs, protection from ultraviolet rays, and overall noise reduction. Heat Mirror was used in the Empire State Building retrofit, replacing 6,514 windows with high-performance glass; in the Museum of Flight in Seattle, WA; in the Princess Elisabeth Antarctica, a Belgian scientific polar research station; and in many modern houses. 
  • Quantum2 Windows by KensingtonGlass™ - Quantum2 windows utilize suspended film technology in order to boost thermal performance; this means it helps your home stay warmer in the winters and cooler in the summer months. 99.5% protection from UV rays ensures that fading is markedly reduced, while fusion-welded frames and sashes keep the windows virtually air-tight, reducing losses.
  • Energy Efficient Windows – Our energy efficient window offerings are provided by Kensington High-Performance products that have the optimum combination of energy efficiency and aesthetic appeal. They are made with glass chambers filled with an insulating krypton gas before being sealed with foam-filled insulation so that there is a minimal amount of heat loss in the cold months and cold air doesn’t seep out when it’s warm.

There windows are top notch. If you do your research you will no doubt decide on them. Our new windows look fantastic and we saved on energy costs this past winter. The install went smoothly and they surprised me by being so neat. I had Anderson and Pella quote. They are brand names that come with a price. When you compare ratings and quality I decked to go with All Pro.
