Surpasses Energy Star Standards
Energy costs continue to rise, and it may seem there's nothing you can do about it. But there is: Reduce energy consumption in your home to lower your energy bills. Replacing older or less efficient windows and doors with Energy Star® compliant Envirosealed windows and doors can reduce up to 15 percent of your heating and cooling costs.

Part of you wants to save your planet. And part of you wants to save your pocketbook. Buying products that are Energy Star® compliant satisfies both those wants. By installing the highest performance windows and doors, you can turn energy loss into saving cost, recouping up to 15 percent on your home energy bills, with potential savings of up to $200 a year. That's a significant chunk of change.

And the U.S. government is with you, encouraging you to buy products that make a difference. With its thermal efficient, patented air pocket design and the lowest U–value available, the Duralite® insulating glass spacer in Envirosealed window and doors is making that difference, meeting or exceeding Energy Star requirements for high–performance windows and doors. Our windows will reduce your heating and cooling costs while protecting the environment with lower carbon emissions. It's a win–win.
