Review on Premium Energy Insulation Stairway Opening by John Hashman

A wonderful insulting sleeve. I'll be honest when I say it came folded more often than a pack of cocktail napkins. ONCE I read the instructions, unpacked it and put it outside to relax. In the sun it became very easy to control it and see how it would work. . The zips are a good size and don't look like a cheap zip from a bread box. As soon as I zipped it up, I immediately felt the temperature change from the cool air inside the closet to the fire-breathing dragon breathing through the draft. Cover at the top of the stairs. The closet is no longer a heat source for our air conditioner. It's amazing how this cover keeps our HVAC unit from cycling. The only problem is that this is not a slow climate gradation. You slide down the stairs without noticing the real heat, open the lid and feel the heat. Instant swamp ass and sweat dripping down your crack. This is probably one of the best thermal products I've bought.
