A 15-pack of clear polycarbonate panels, each about 47.6 by 23.8 inches and 6 mm thick, meant for greenhouse walls and roofs, cold frames, pool covers and shed glazing. The twin-wall polycarbonate is light, tough and UV-treated, and it insulates better than single glass or thin acrylic. The panels ship with a protective film and striped cut guides, so you trim them to your frame. Against glass, they trade some clarity for impact resistance and warmth; against cheap single-sheet plastic, they are stiffer and hold heat better.

Buyers use these for greenhouse repairs and small builds and generally find them light, easy to cut and good at holding warmth. Complaints center on the hazy look and on film or edge sealing that takes extra work.
These polycarbonate panels are sold as a set of 15. They are made of clear, high-transparency polycarbonate with UV protection. They let in plenty of light, block UV rays, and support plant growth.
The panels can be used as roof panels in any season. They keep light transmission high to help keep greenhouse temperatures stable and reduce plant wilting from temperature swings or too little sunlight. They also provide insulation.
They can be installed on garden greenhouses, plant shelters, walkway roofs, garages, and indoor pool roofs. Striped guides on the panels help with precise cutting. Peel off the protective film before installation.
