Last year we bought a greenhouse to extend our growing season from the company http://www.deltacanopy.com
Almost 1 year later we are removing the greenhouse.
According to the website the film is now UVA and UVB protected, I don’t remember it that way before.
This Polyethylene film was not UV protected. The plastic was brittle, cracking, shrinking, and ripping with the press of your finger. If you buy a hot house like this make sure the skin is UV protected.
On a side note, the 1.34 inch steel welded frame is holding strong and can easily be skinned with another plastic.
