Large industrial projects usually use commercial grade Polyethylene. Another way to reduce heat loss is to double- layer the plastic creating an air pocket for insulation. The films high translucency ensures good light diffusion and reduces shadows. Available in both acrylic and polycarbonate, these are double skinned (for insulation) or corrugated. Too much shading, on the other hand, can cause plants to deteriorate from a shortage of energy. By removing the condensation drops that block the sun's rays, this new type of film plastic allows more light into the greenhouse. And while polycarbonate is much more durable than both glass and polyethylene, it is far costlier than both. In this case, polycarbonate greenhouse covering is the best option because it is the most transparent. Choosing polycarbonate will still provide some longevity, typically lasting about 15 years. The air pockets between polycarbonate sheets stand up well to extreme weather conditions, since they retain heat in cold temperatures and stay cool during warm months. Polycarbonate, typically the most expensive greenhouse covering, has a warranty period anywhere from three to ten years, depending on the manufacturer (quality can vary greatly). Shatterproof, they resist hailstone damage to varying degrees polycarbonate being the strongest.

It is because Polyvinyl can last for five years or more if kept in optimum condition. What glazing material should I use to cover a hobby greenhouse?
exposure. Plants respond best to diffused light. Use a material that will let in the maximum amount of light while allowing the least amount of heat to escape. Other greenhouse coverings provide little to no light diffusion, which increases chances for burning and can cause the greenhouse to overheat. capacity to reduce the amount of dust sticking to the film. For those who need a woven greenhouse cover, plant production is more than just a hobby.

According to researchers Giacomelli and Roberts of Rutgers, glass is the ideal material for greenhouse glazing because it provides the best light transmission out of all the various coverings and has a higher comparable thermal rating. Therefore, the higher the strength, the lower the probability of breakage and the resulting costs associated with replacing the glazing. It diffuses a soft shiny glaze that is good for any type of plant. What is difference between ETFE and SolaWrap? Many growers consider this safety issue a good reason not to use fiberglass.
