Use polycarbonate sheets to construct the most rugged greenhouses and enclosed patios in areas known for severe weather or vandalism.Our 6mm and 8mm twin-wall polycarbonate panels offer high impact resistance, excellent heat retention and 80% light transmission. These panels block ultraviolet rays that burn plants and living tissues, only transmitting beneficial radiation. Avoid expensive shipping and crate charges by ordering Easy Ship 2-Feet Wide Twin-wall Polycarbonate Panels that ship via Standard Ground Service.

This double-wall polycarbonate is designed and engineered specifically for commercial greenhouse use and offers 99.5% UV protection. The two-wall design and light weight of the sheet means a reduced cost for the supporting structure since it doesn't need to support as much. Shatterproof polycarbonate coupled with integrated UV resistant co-extruded layer yields long service periods backed up by a 10-year limited warranty against yellowing from UV rays. The cellular multi-layer structure reduces heating costs in winter while minimizing excessive heat in summer. A special coating on the bottom side eliminates condensation dripping.

Whether you need clear twin-wall polycarbonate panels for a greenhouse, shed, pergola or outdoor pool, our Easy Ship sheets provide DIY usability with professional results. We offer lengths from 4 to 8 feet, letting you build all sorts of structures as-is or by cutting them to the right size and shape.

I am installing the Twinwall polycarbonate sheets now on my greenhouse and I am quite pleased with these panels. They are strong and very easy to cut. Glad I found them on the internet.

Twinwall Polycarbonate

Have had a small greenhouse covered with Twinwall for over twenty years, needed to reglaze a couple of years ago due to weathering. A significant hailstorm forced me to do it this year. This stuff has staying power at 8,300 feet of elevation.
The Megastore shipped a 10 pack and it arrived in good shape and quicker than expected. I would certainly use them again.

Stevan Strieck

material arrived in good order and was clearly marked as to how to install. These panels seem to be of good quality and the only problem I had was due to the measurements of my greenhouse which required me to trim 1/8 inch off each piece because they were slightly to wide to fit my greenhouse. very pleased with the end result.

Legacy Review
Better than the last one, but room for improvement

I bought 2'x6' Twinwall Polycarbonate (TP) sheets from Greenhouse Megastore to replace some much cheaper panels that came as part of a 6'x8' greenhouse kit I bought from another store. These TP panels are not 2' wide - they are about 1/2 inch wider. That's not giving me more product. That's giving me more work because I had to cut 1/2" off the entire length to get them to fit. The inside of the TP is coated with a white, translucent film to filter a bit more sunlight and UV. Great concept - but in less than a year, the white film starts to peel off and has to be glued back on with silicone. These TPs are better than the panels I'm replacing, but that's all. GM says "...they come from the mfgr that way..." so they're no help either. Buyer beware.

Great replacement panels

I found these a few years ago and I have been replacing the 4mm panels in our greenhouse with these. They clear and strong. I have used a plywood blade on a table saw to cut them. nice clean cuts.
