Guide to Energy Ratings for Windows & Doors

You know your home needs better quality windows and exterior doors, but just exactly what should you be looking for when trying to choose the highest efficiency options?

What Do Energy Ratings for Windows & Doors Mean?

In order to gauge how energy efficient a certain window or door is, there are two factors you have to pay attention to. These include the U-factor and the solar heat gain coefficient (SHGC).

  • U-Factor

The U-factor indicates the window’s resistance to heat. The values for the U-factor range from 0.20 to 1.20, with a lower number indicating a higher resistance to heat and better insulation, resulting in greater energy efficiency.

  • SHGC

The solar heat gain coefficient (SHGC) is the fraction of solar radiant heat a window admits. It’s expressed as a number between 0 and 1, and as with the case of the U-factor — the lower the number, the less heat is transmitted signifying higher efficiency.

Benefits of Energy Efficient Windows & Doors

Apart from increasing your home’s energy efficiency, new windows and doors can also increase curb appeal and boost the value of your home. It’s important to select the most energy efficient options to ensure you get the most out of your investment while also qualifying for PACE financing.

Financing Your New, High-Performance Windows & Doors with PACE

PACE or property assessed clean energy financing allows you to borrow up to a set percentage of your home’s value to use for energy efficiency improvements. Projects like windows and doors qualify if the selected options are energy efficient. With PACE solutions from CaliforniaFIRST, HERO, and Ygrene, you’ll be able to increase the energy efficiency of your home easily while repaying your financing over time on your home’s property tax bills.
