Energy-Efficient Windows

Quality windows let in the light—and that’s all they should let in! At Progressive Insulation & Windows, we offer top-quality windows and expert window installation to make sure that air, drafts, dirt, and solar heat gain are not able to use your windows as a path into your home. Some of the most important energy-efficient features we’ll help you look for in your windows include:

  • Low E Glass: With the strong California sun beating down on your windows, certain rooms can get quite hot. Installing windows with Low E glass helps prevent this by blocking up to 80 percent of solar heat passage through the window.
  • Low Conductivity: Metal window frames can also heat up in direct sun and end up transferring heat into your home. By installing windows that have frames made from materials like vinyl and wood (which have low thermal conductivity) you can prevent this problem and support the energy-efficiency of your home.
  • Draft-Minimizing Design: Today’s windows are designed to be much more airtight than older windows. This helps reduce drafts so you have less conditioned air leaving the home and less outside air coming in.

Why Choose Progressive

If you want to improve your energy efficiency, buying high-quality windows is just half of the job. You also need to make sure these windows are installed correctly with proper insulation by a qualified contractor. At Progressive, we have a specialty C-17 license marking us as an expert in window installation and window insulation, as well as decades of experience. You can rely on us to get the job done right the first time, and your satisfaction is guaranteed with our one-call warranty.
