Great sheets thanks

We wanted to winterize our chicken coop. These worked perfectly! They are lightweight and durable. They let lots of sun in but not when nor cold. We are thrilled with them and so are the chickens.

My greenhouse came with 2 foot wide panels. These panels are about 23 inches wide so I'll have to splice the panels. You can still purchase 2 foot panels from home improvement centers but they are around $40 per panel. My option is to try using greenhouse tape and silicone caulk. Maybe I can make these $130 panels do the job, instead of spending $500. Time will tell if it works or if it leaks. I expect to lose some sunlight but the old panels had deteriorated significantly in the 5 years since the green room went up. They got brittle due to sunlight and a minor hail storm punched holes in the surface, plus etching on the surface. I'm hoping these panels have a longer life. I expect the tape to yellow in 3 or 4 years.

Great product to help keep our screened in porch warm for our cats during the winter. It has made a big difference. I did leave a corner area without the panels to allow ventilation during the day time and am using curtains and have a thermal panel ordered to put up in the corner to really help when it gets really cold. We bought the H strips to link them together and he dust proof tape to put on top and used duct tape in the bottom. They are screwed in so we can remove them in the summer time.

I had to replace panels that got blown out in high winds, I didn’t have the door secured so the winds were really swirling. So far the replacements are holding up great and we had a couple of more high wind days and they held. 2 panels needed to be cut down they cut very nicely without splintering.

These worked perfectly for our new deck. Wanted something lightweight but transparent for sunshine. We copied the greenhouse effect & can't be happier. We've had a few snowfalls & it is holding up. We use a roof rake to pull off the snow.

Not a bad product, but not a good product. Just ok. It is a little flimsy. I can't return the product because I already cut the product for my project. Going to Low's to buy some higher quality panels. I don't think this would be a very good product for a roof structure as what I am using it for unless you have a lot of support.
