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

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

If improperly installed, an egress window can compromise your foundation’s structural integrity, so it’s important to work with a pro to ensure your foundation remains in good shape. Any money you may save on a DIY egress window installation may cost you in the long run if your foundation is damaged in the process.

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.
