It’s the zipper. Bought and installed a new attic ladder and the handyman installer did not center it properly. He left a hairline opening that I initially didn’t notice along one side. Hallway where ladder is located became drafty. I ordered new insulation and the insulation installer told me I needed an attic ladder cover – “the kind with the zipper.” I installed the ThermoClimb Adjustable Attic Stairway Insulator cover with the zipper myself and noticed the different almost immediately. Air movement in that hall is gone. The ThermoClimb Insulator cover comes with two zippers, either of which will zip all the way around. However the zippers are cheap and lightweight. One pulled apart within days of installation. Product does work but it could be even better.
Performs Well, Easy to Install
Easy to install and you can immediately feel the difference in the temperature as it is being stapled in! Hot air was pouring in around the attic stairway closure and I'm certain the the AC cool air was escaping. Once installed, I used a laser thermometer and saw a 6 degree drop in temperature. I wish that I would have purchased the TermoClimb long ago. Don't hesitate. Buy this now.

This product came without a frame, and without one it is a flop. I built a frame with PVC, which was an a additional cost. It is effective, but should come with a fame. I would not recommend this to someone who isn't a handyman and has a few necessary tools.
