Breeze Stop Surround Window AC Insulation is composed of three panels that connect around a window AC to provide both insulation and a clean built-in look. The side panels can be cut to size with a scissors and have an adhesive flap that connects the panels to AC. The top panel form fits the top of the AC to provide insulation in areas that no other foam panels currently available on the market do. Although all the panels have adhesive flaps to connect to each other and the window AC the panels should stay in place without applying the adhesive as well. This allows for super easy removal without leaving over any residue on the AC from the adhesive. At BreezeStop we are committed to finding new and innovative ways to improve home insulation and help conserve energy. Our products are patented.
