Clear Patterned Greenhouse GlassThickness: 3.2mm, 4.0mmApplications: Roofs and side walls of Greenhouse projectsPatterned greenhouse glass is a kind of diffuse glass which generates the best possible light transmission by scattering the direct sunlight that enters the greenhouse. Diffusion of the light ensures that the light penetrates deeper into the interior and in between the crops, illuminating a larger leaf surface area and allowing more photosynthesis to take place. This benefits the growth and quality of the crops. ●MIGO Clear Patterned Greenhouse Glass is a 3.2mm or 4.0mm Normal-iron Mistlite Tempered Glass. It is featured with a prismatic pattern on one side and a matt pattern on the other side.●Clear patterned glass is toughened under high temperature in a furnace. Toughening  (tempering) treatment makes the glass four to five times stronger and safer than original glass.  ●MIGO Clear Patterned Greenhouse Glass is fully tempered as per CCC and EN12150. ●MIGO Clear Patterned Greenhouse Glass fits for all kinds of greenhouses: Venlo greenhouse, Cabrio greenhouse, Wide Span greenhouse, and etc.TECHNICAL SPECIFICATIONSLight Transmittance3.2mm (1/8"): 90%;  4.0mm ( 5/32"): 88%Thickness tolerance   ±0.2mmDimension tolerance           ±1.0mmDiagonal difference            ≤0.1-0.2%Iron content (Fe2O3)                  3.2mm (1/8"): 498ppm;  4.0mm ( 5/32"): 594ppmOverall Bow/warp             ﹤0.2%Local warp                   ≤ 0.3mm / 300mmFragmentation Test   ≥79 particles within 50x50mmMECHANICAL & THERMAL CHARACTERISTICSScratch hardness 4~5 Poisson's Ratio 0.2 Density 2.5×10³ kg/m³ Tensile Strength 42N/mm2 Pressure resistance 700-900N/mm² Four Point Bending Test ≥146.7N/mm² Coefficient of thermal conduction ≤ 1.36 W/(m*K)
