Be Cool Solutions Polycarbonate Panel, Twin Layer 4mm Sheet, 5 Pack, 2' (W) X 6' (L)- Cold-Flexible, Clear, Strong Impact and Shatterproof - All-Weather Outdoor Garden and Greenhouse Covering

Used to cover basement well window.

High winds ripped away one roof panel and took it to who knows where. This panel was easy to cut to size and fit in the support slots like a glove.

This was my second go-round for the panels, they're good replacements for the original Harbor Freight aluminum greenhouses, Unfortunately, here in the southwest, they have a rather limited lifespan - heat, wind, and ultraviolet kills them in a few years. Luckily, they're not prohibitively expensive. I was rather appalled at the shipping container however - I'm sure that no one instructed the person packaging the sheets to reinforce the box as the copious amount of packing tape was loose and bordered on worthless, and why not put the two sheets I ordered in one box, why two? Some packing paper thrown in and a roll of tape on the outside...tsk, tsk. Well, I can use the excess cardboard for target backing on my shooting stand. Product was as advertised however.

I used these as replacement panels in my greenhouse. The old ones had turned yellow and became brittle. New panels are clear and flexible. My greenhouse looks new again.

The material was so flimsy it could not be cut without shattering even though a special blade, indicated for poly carbonate, was used. This poly also needs to be sealed with a "permeable tape" which is impossible to find. A total wasted of time, money, and energy.

Replacing 25 year old sheets

Main advantage; shipping thru Amazon was included. Corners were slightly damaged. Cut with circular saw with a 140 tooth blade and a stright edge track.

Worked very good. Very expensive.
