Home Efficiency in Alameda, Contra Costa & San Francisco

Windows help make our homes enjoyable by providing light, views of the outdoors and ventilation. But they can also be a culprit in your home's energy loss and air leakage. Finding the right kind of replacement windows is essential to improving your home's comfort and energy conservation.

Energy Efficient Window Replacement in Alameda & Contra Costa Counties

When Mason BPP conducts an energy efficiency audit, we often find that windows are allowing outside air to infiltrate and are letting your expensive indoor heated or cooled air leak out of your home. Sometimes these cracks and leaks can be solved with simple caulking and sealing. However, in many cases, the window itself is not providing the protection you need.

The good news is that replacement windows qualify for both California PACE financing and Energy Upgrade rebates and incentives. Window replacement with Energy Star rated windows can cut 7-10% of your home's energy costs, according to the Environmental Protection Agency (EPA).

Replacement Windows for Energy Efficiency

There are many types and grades of replacement windows available in our area. What are the elements that can affect a window's energy efficiency? We're glad you asked. Here are some of key factors:

U-Factor Rating

Each window should be labeled with information about its rate of heat loss, measured in U-factor. Unlike insulation R-factors, where a higher number is better, with U-factors, a lower number means the window provides better resistance to energy transfer.

Window Frames

Replacement windows are also available with different frame materials, including wood, aluminum, fiberglass and vinyl. Each of these materials conduct energy differently, so look for a U-factor rating that includes the entire window, not just center glass. Again, a lower number is better!

Retrofitted or Constructed Installation

How the new window is installed can also make a huge difference in energy efficiency. Retrofitted replacement windows remove the old window and place the new window into the existing opening. This can carry over many of the leakage and structural problems that caused the original window to fail. As many as 10% of retrofitted replacement windows fail because of poor installation techniques.

Mason BPP recommends a construction replacement window, where the old window is taken out, and the structure around the window is reconstructed, if necessary, with new framing, flashing, water sealing and caulking.

High Efficiency & Sustainable Windows

As a LEED Approved Professional, Mason BPP has designed and constructed many of these high-efficiency and environmentally sustainable homes.
