We manufacture Advanced Energy Panels (AEPs). AEPs are a retrofit for historic windows or any window people can't afford or don’t wish to replace. AEPs are interior window insulating panels and can be installed in any building –office, home or industrial. AEPs have a higher insulation and air sealing rating and provide greater comfort than most replacement windows, yet they are a fraction of the cost. AEPs are custom made to fit over existing openings, protecting, preserving and improving your existing windows.

Egress Windows questions, answered by experts

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old windows.

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

When you need new windows depends on a variety of factors, including the age of your windows, the age of your home, and the climate you live in. If you’re dealing with budget constraints, you don’t need to replace all your windows simultaneously. 

When buying new windows, you should consider energy efficiency, safety, and aesthetics to choose the right window for you.
