15 Pack Polycarbonate Greenhouse Panels, 4' x 2' x 0.24'' Twin-Wall Polycarbonate Sheets, Greenhouse Replacement Panels All Weather Clear Roof Panels

This is as advertised and a great deal.Our existing panels were 4mm but our greenhouse would accept thicker so we went with these 6mm. We needed to cut these down to fit our need which was easy. Always remember to put your saw blade in backwards when cutting material like this. Very pleased with its quality and value.

Used these to enclose an area off our shed for my son’s outdoor toys.Super easy to use, great size, easy to cut. Would use again

Sturdy, these are well-crafted and slide into the routed slots with ZERO issues. These are white opaque and need to be sealed at the edges to prevent water seeping into the panels. GE Silicone is a good choice.

I have yet to install. Package arrived very fast and in good condition. 8 pieces 4x8 for under $300. Lowes sells one piece for $99. Lowes are a little stiffer but, in my application, I need flexibility. Replacing skin on a 20-year-old aluminum double wall greenhouse. These panels should withstand tree branches falling on greenhouse. Satisfied so far.

Quality product

This worked for my project. Bermudan windows for my lanai. The edges are sharp and I need to find something to make the edges smoother. I thought they were going to be white but they are clear. I kept the white plastic on them for now. Will paint them white soon.

No structural integrityWarp when hot, lifting off roof.Don’t recommend for greenhouse roof!

Was as advertised,ordered more to replace my greenhouse panels. Fast shipper
