Diffuse Glass for greenhouse
Glass has been used as a greenhouse glazing material for many decades primarily because of its high transmission of light and longevity. Although glass transmits a high percentage of sunlight, most of that light penetrates through the glazing in a directional manner; very little is diffused.
Diffused glass is usually created by treating the surface of the low-iron glass to create patterns that scatter the light. Compared with clear glass, diffused glass can:
- Increase the uniformity of the greenhouse climate, especially temperature and light conditions
- Increase fruit production (by 5 to 10 percent) of high-wire tomato and cucumber crops
- Increase flowering and reduce the production time of potted crops such as chrysanthemum and anthurium.
Diffused glass is divided into:
Clear Matt Tempered Glass
Low Iron Matt Tempered Glass
Clear Matt Tempered
Low Iron Prismatic glass
Low Iron patterned glass formed with a matt pattern on one face and a matt pattern on the other face.This ensures the highest energy transmission over the whole solar spectrum.
Low Iron Prismatic glass formed with a matt pattern on one face and the other side is smooth.
Tempered Glass conforms to EN12150,meanwhile, we can make Anti-reflection coating on the glass.
