ENERGY STAR® was created to help consumers easily identify products, homes, and buildings that save energy and money, and help protect the environment. As the government-backed, trusted symbol for energy efficiency, the ENERGY STAR label identifies highly efficient products and designates superior energy performance in homes and buildings.
Pella is proud to offer our customers windows and doors with the ENERGY STAR label because they:

Look for the ENERGY STAR label. Pella Corporation is a proud volunteer partner in the Department of Energy’s ENERGY STAR program to promote the use of high-efficiency products.
Most Pella® products with Low-E insulating glass meet or exceed ENERGY STAR guidelines in all 50 states.* In fact, we have some products that have U-Factors that significantly exceed U.S. ENERGY STAR guidelines.
Some Pella products may not meet ENERGY STAR guidelines in Canada. For more information, contact your local Pella sales representative or go to energystar.gc.ca.

It’s easy – just look for the labels.
What to look for in energy performance. This is the most reliable way to determine a window’s or door’s energy performance.
1. 1. NFRC-Certified products. Reputable window manufacturers rate and certify products according to National Fenestration Rating Council requirements.
2. 2. U-Factor. The lower the U-Factor, the better the window insulates.
3. 3. Solar Heat Gain Coefficient. This number tells how effective the product is at blocking the sun’s radiant heat. The lower the solar heat gain coefficient, the less solar heat the window allows into your home.
4. 4. Manufacturer reports “whole product energy performance” – the best way to know how your window will perform – versus only reporting performance of just the glass.
The National Fenestration Rating Council (NFRC) is a non-profit organization that developed an energy rating program based on whole product performance – not just the glass.
