Glass: Critical Component of Our Sliding Patio Doors

Many of Renewal by Andersen®’s choices of patio doors come equipped with special glass that contributes to the overall energy efficiency of the home. This is important especially for our sliding patio doors, which are known for their expansive glass areas.


High-Quality Glass

Some sliding doors do have glass, though they only consist of only a single panel. Such fixtures tend to transfer heat more than the traditional French patio doors. When this happens, the indoor heating and cooling requirements increase, leading to increased energy consumption and higher bills every month.

This is why Renewal by Andersen’s sliding and French doors are equipped with high-performance glass with low-emissivity properties. Special coatings are applied to block ultraviolet rays and allow visible light to enter the home. Double glazing is used, with argon blend filling the airspace between the two glass panels for better thermal performance. This creates a more comfortable home during the summer and winter.

Glass Packages from Renewal by Andersen

Every home is unique when it comes to energy efficiency, which is why the company offers glass packages with various qualities of UV protection, visible light transfer and heating and cooling performance. Here’s a look at three of them:

  • High-Performance™ Low-E4® glass – This is the standard glass for all Renewal by Andersen window and door offerings. They have been known to effectively cut energy costs up to 25%.
  • High-Performance™ Low-E4® SmartSun™ glass – This glass option blocks as much as 95% of harmful UV rays while filling up your room with natural light.
  • High-Performance™ Low-E4® Sun™ glass – This glass option has an exterior tint for the right amount of sunlight to enter your home. It also has the highest rating against solar heat gain, keeping your home cooler during hot weather.
