10 Pieces 4' x 2' x 0.24'' Polycarbonate Greenhouse Panels,Twin-Wall Polycarbonate Panels Waterproof UV Protected Impact Resistance Reinforced Clear Roofing Panels

The ease of cutting without special tools is huge!!! Unless you need cubes then a Sabre saw would be very helpful. The 4mm thickness was sufficient for my greenhouse. The clarity is as advertised. The Maine winter will be the test of strength and durability however. Be sure to read up on installation procedures regarding drilling holes for screws, type of screws, vertical vs horizontal, which side facing out for UV benefit, etc!! I will say that if using the H channels to connect 2 panels it is not easy for the full 48”. The trick is to start at the end and slide the panel along from bottom to top. It can be hard to do and would help if two could work together. I don’t recommend a windy day to do your project.

We are having to replace the panels in our Greenhouse and are very pleased with these. They have made a tremendous difference in the light able to come in. Very durable and easily cut to size. Recommend.

Easy to use, cut and apply; we shall see how it stands against time and weather

I used this for doing aquarium lid on a 40B, and I somehow was expecting this to be more strong. It serves the purpose of my cats stopping to drink in it, but I am worried that if the cat jumps on it, it would bend and the cat falls into the tank.I wanted to convert all my tanks to this, but may just switch to doing small green houses for plants instead.

These sheets were a bit thinner than I thought they would be, but very flexible as I needed to bend them for corners. They are crystal clear. Built a wooden frame around them for wind and weather support.

Our hobby greenhouse is around 20 years old and was in serious need of new roof panels. Each panel had to be custom cut, which was no problem with a sharp utility knife. Even the original J channel used to seal off the cut sides fit these new panels. The panels were delivered at 4 pm, the finished pic was taken at 7:40 pm, easy job!

Possibly the issue are all specific to this one set but the bottom line is that it's been nothing but issues.With all of the complications wasting hours of my time I'm simply unwilling to give it another shot.

They are sturdy, super transparent, and exactly as described. I was able to use 8 on my 16ft side of green house and still have about 5 panels left over. Will DEFINITELY be ordering more.
