Features
- High Weather Resistance: UMIG polycarbonate panels are made of high-strength polycarbonate material with a density of 1.2 kg/m2. Its impact strength is 200x that of glass and 30x that of acrylic. The 0.32in thick panels can withstand hurricanes, snow and hail, making them suitable for harsh climate regions such as the northeast U.S. zones
- Double-sided UV Coating: The plastic greenhouse panels are coated with a uv coating on both sides, so there is no need to distinguish between the front and back during installation. Compared to panels with a single-sided coating, this design reduces yellowing and cracking of the panels while also saving installation time. It creates an ideal environment for plant, lower indoor temperatures in summe and providing warmth in winter to ward off frost while reducing heating costs
- Ideal for Professional Gardeners: The plastic roofing sheets measurs 4 ft 2 ft (47.2in x 23.6in), single layer thickness of 0.32 inch (8 mm). This means it's lightweight and easy to transport. Unlike bulky traditional greenhouse panels, it doesn't require heavy equipment and can be easily installed by one person. Compared to our 0.24in thick panels, the 0.32in thick panel performance in resisting hurricanes and blizzards, making it ideal for gardeners who prioritize long-term planning

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!

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

light wt but seem sturdy. I used them for parts of my home built scrap wood green house. Easy to handle and with a hand saw easy to cut. I'll know better by this time next year what I think but for now I'm quite happy.

These are awesome. I didn’t even use the snap-in brackets. We just finished installing these as a very unconventional thin and lightweight roof for my greenhouse with a lot of time final constraints. I used the greenhouse repair tape to seal the joints and covered it with the sheet roll Of polycarbonate/fiberglass and anchored it to the joists with prescribed screws. It underwent a hellacious hard rain with no leaks so far. The materials are great and the channels seem to allow for a lot of light to come through without any significant amount of heat gain! I would definitely buy again.

This is one of those things where you get what you pay for. Compared to the more expensive polycarbonate greenhouse panels that I get from the hardware store, these are pretty flimsy and I doubt they will last very many seasons out in the weather. There not bad per say, but since I have the knowledge of what good panels are, I was more neutral in my enthusiasm for these. Nonetheless, I've learned my lesson and will splurg for the nicer more hefty greenhouse panels in the future for my greenhouse projects. Overall this product was packaged well and arrived undamaged. This product would still work for someone who is on a budget, wants to experiment with greenhouses, cold frames, temporary greenhouses over frost-intolerant plants. However, if you can afford it, I would recommend going with more expensive and more durable panels from the hardware store. Happy planting!
