UMIG 12 PCS 4' x 2' x 0.32'' Polycarbonate Greenhouse Panels, Twin-Wall Waterproof UV Protected Corrugated Plastic Roof Panels Sheets, Clear Replacement Panels for Greenhouse, Outdoor, Plant

I have a whole new greenhouse. Very good quality and came packed with care and they cut and slide n easily. I would and probably will repurchase after another windstorm.

Easy to trim. I've had these for about a year now and they are still going strong..

On time & works well . Used them as a wind break on a carport.

Absolutely loved this. I wasn't sure at first when I bought them if I was going to like the thickness but they are sturdy enough without being overly thick. These were actually purchased. Put around a chicken coop for winter. I love that they almost interlock on the edges due to the edge design. It has increased the temperature in my run by several degrees just by decreasing the wind and on sunny days. It does warm up much quicker in there. I'm sure these would work wonderfully for a homemade greenhouse as well

We installed them in our greenhouses good product easy to install them

Double sided uv a plus. Can't get them mixed up. First shipment was damaged from shipping, but was replaced with no hassle immediately.

We had to cut for length but a good box cutter worked just fine

I used this to make 10 aquarium lids and even though I have many sheets left over, it has saved me so much money. Aquarium lids are expensive and I don't have a garage where I can use power tools. So being able to cut this material with a utility blade and save hundreds of dollars has been amazing. I appreciate that these sheets were very well packaged with plastic corners on all sides to preserve them from getting any damage too. They came in excellent condition and are very strong panels!

MY outsunny greenhouse panels lasted a whole 2 seasons before they became so brittle that small hail punctured holes all over the roof, now the windstorm the other day blew the roof panels into pieces even though i had reinforced them to not flex in wind. Luckily I was able to order these panels and get them the very next day. Cut them to size and installed right away. I got the panels a bit thicker than what my greenhouse came with and just pinched the edges to fit into the slots. overall this feels much more durable then the original. So far very happy. hopefully they will last more then 2 years.

Perfect for the greenhouse. Easy to install!

I have finally gotten around to working with these. I taped up the ends. I first did a 1 inch copper tape I had. Then 2 inch gorilla crystal clear over that. Hopefully it holds up. I did the copper for looks. I am building a wooden greenhouse and the copper looks great with the stain color I chose. That all said you do get what you pay for. These compared to the ones from home Depots (made in the USA) are night a day difference in price and quality. The inner walls on these panels are about the same size as the hardware store brand. But the outer walls are very thin. Like plastic bag thin in the middle. And I can see imperfections like holes or air bubbles in the panels here and there. I plan on addressing those spots as I install them with a splash of epoxy or silicone. I am using these as roof panels. So they need to be strong and sealed. I noticed a video online where a owner of a habour freight greenhouse shows a update video after years of ownership. She is puzzled over the tiny holes in her panels over time. She blames her neighbors fires. Hail.... But I figure they were always there. Like the bubbles or holes that appear in my new panels. That all said you can't really complain much as these are so cheap in comparison. Just know what you are getting. I figured it was worth the gamble. But this one sheet I have left over from another project is way better quality. One it's just perfect. Two it's actually 2 feet wide. 3 the sides are closed with a rounded over. And 4 all these things just makes them stronger. I may regret using these in the long run. I will just replace them as nessasary as they fail with the better ones. I think these are great wall panels and good to get this greenhouse going on the cheap. But for a roof I don't see them lasting. I think a pine cone or stick falling from a tree or hail will kill these on a roof. They just don't look up to the task. I am considering putting 6 mill greenhouse poly over them to add some strength and longevity. I also question their claim of UV protection. The other panel I have has a this side towards the sun label on it. That side has the UV protection. These you can use any side towards the sun. Seems strange. Hopefully this review helps others looking to make a informed decision. I know this information would of swayed myself.

Great product, good quality.
