Product Details

Common Names: Polyblock 

Material Pros: 0% light transmission, high thermal insulation 

Popular applications: Artificially lit greenhouses 

BlockOut sheets are a multiwall polycarbonate designed as an alternative to corrugated metal for artificially lit greenhouses. The material is lightweight, yet still durable enough to withstand wind and snow loads with less structural support. Blockout allows 0% light transmission while still offering high thermal insulation. It creates a steady temperature range by reducing heat penetration during the day and insulating against cold at night. The material offers full environmental control for plants like cannibas, that grow better with a light – dark cycle and steady temperatures.  

BlockOut sheets are lightweight, easy to install, and compatible with other multiwall sheets. This allows growers to use BlockOut as a roofing solution and standard sheets as wall panels. If your greenhouse project requires light transmission, check out Polymatte. It offers high light transmission with 100% light diffusion. Have questions?
