My experience seemed clunky with the correspondence process but we got through it. The measuring process I did twice because I thought we were off a little. Ultimately upon receiving the product that piece was/is off. And the door and vent panels aren’t as air tight as expected. I was also shocked at the cost of of the door panel, vent panel and shipping was ridiculous. However my wife wanted to make our porch more livable in the cooler months so here I am. Thank you and I’d to make sure we address the panel that has gaps.
