Review on 🔒 Pearwow Insulating Foam Panels for Window Air Conditioners - Effective Summer and Winter AC Side Insulation for Energy Efficiency by Flip Shaw

This piece of styrofoam is a waste of money. The goal is to keep your block by the window while keeping the draft out. Don't count on it. You'll have to cut the styrofoam to fit the block with the block in your window, easier said than done. You can get a piece of styrofoam a lot cheaper anywhere and do the same thing. My window is 1 of 2 side by side so there is nothing to tape. They don't bother to say it's for a window. Waste of money and more importantly, waste of time.
