Would recommend to everyone fast service great product
I used this for a divider between a old and new garage addition in my house.
Installation was simple and even thou no instructions where included, it was simple to assemble and install.
Even the county inspector loved it and requested the information for himself so he can install one.
The cut out at the top allows the plastic to over lap each other creating a great seal. I live in Florida and I am planning on putting in a mini split on the new garage addition side and this will prevent the cool temperature from the one side to escape to the other side.
This product was easy to install and provides a perfect climate barrier. Will recommend this product to others and would definitely purchase several more.
