Window insulation

Don’t replace those drafty windows – insulate them, with WindowTherm.

WindowTherm insulation panels are not storm windows, nor are they replacement windows. Rather, they are affordable, custom-built and environmentally-friendly window insulation panels, specifically designed to increase your comfort level and save you money. And they install easily on the inside of existing windows.

Windows are a primary source of air loss, and therefore mainly responsible for high heating and cooling bills, and even noise transfer. And replacement windows, no matter what kind of building you have, are almost always expensive.

Instead of spending thousands of dollars on replacing your drafty windows, stabilize indoor temperatures and reduce sound and noise by up to 70% with help from WindowTherm.

Our powerfully effective and easy to use window insulation panel provides instantaneous comfort as well as substantial energy cost savings, every single day. 

We’ve helped people all over the United States improve the performance of their windows. Get a free no-obligation estimate, or contact us to learn more about how our talented staff can assist you.

Thank you for your patience while this site is under construction. 
WindowTherm window insulation panels were formerly Advanced Energy Panels (AEP).

A Change in Government.

 
 
“Advanced Energy Panels have made a dramatic positive impact for the city with regard to reducing future energy costs, and they provide a warm climate in the winter and a comfortable climate during the summer. We have projected a payback in four years and we are more than on track. On behalf of the taxpayers and all of us at City Hall, thanks AEP! We’re saving tens of thousands a year.”

City Hall Savings.

 
 
“I would like to take this opportunity to thank you and your staff in providing Amsterdam City Hall employees and constituents with such a warm environment in which to do business.
The quality of the insulated panels are resilient, durable and outstanding. The proof is in the savings, time, energy and oh yes – the money! This historical building can once again enjoy its integrity with the clean crisp look of each and every panel being perfectly fit.”

No More Ghosts in the (Political) Machine.

 
 
“Cohoes City Hall was established 135 years ago. It is a beautiful building, but when you deal with the day-to-days issues, it is a nightmare. When I took over in 2000, I thought I had a ghost in my office because even with the windows closed and no wind, I would see the blinds drifting back and forth. To put some kind of window energy efficiency in a historic building like this would cost $300,000 to $400,000. A lot of taxpayers would think that was crazy… We put in cellular shades and they definitely helped, but more importantly, we added WindowTherm’s window insulating panels and they made a dramatic positive impact for the city with regard to reducing future energy costs.
 
They provide a warm climate in the winter and a comfortable climate during the summer. From the outside you can’t tell the difference and inside they fit in perfectly. They look like they were part of the original intent of the building.
Before I put the window-insulating panels in city hall, I brought the Cohoes historic preservation people in and showed them test panels in place. They liked them. They thought they looked good. Anytime I can provide for future savings that will pay for itself in 2, 3, or 4 years it is definitely my responsibility to do so.
It’s a good use of taxpayers’ money, which is important. The WindowTherm panels were installed in 2002. We have projected a payback in four years and we are on track. If we had continued the way we were, it would still be cold, and it still would be a nightmare. I think WindowTherm’s window insulating panels are a sensible fit in a building that has a significant historical component to it.
