Energy-Efficient Glass Options for Every Climate
Designed to work for your specific climate, Pella’s ingenious insulating glass options will help to significantly increase the comfort and thermal performance of your home. Our windows and doors are crafted with two or three panels of glass that provide more layers of protection from the weather, and have colorless nontoxic argon gas, which is denser than air, inserted between the glass panels for optimal insulation.
Our windows and doors also have a low-emissivity (Low-E) glass coating that reflects heat back into or away from the home to keep it warmer in the winter and cooler in the summer. This will help to prevent your home’s HVAC system from working overtime to maintain a comfortable indoor temperature, potentially leading to lower energy costs.
Pella’s energy-efficient features don’t stop there, however. We also offer different combinations of glass, and thermal barriers to provide even more protection against heat and cold conduction. Thanks to all of these features, Pella windows and doors are certified by ENERGY STAR® – the most widely recognized symbol for energy efficiency in the world – so you can feel confident about the energy-saving benefits you’ll receive from our products long into the future.
