Fiberglass Sheet- One of the Best Materials for Greenhouse Roof

Fiberglass Reinforced Panels are made of a durable polyester resin and reinforced with fiberglass. They are ideal wall covering, for interior use in restaurants,fiberglass chopped strand mat kitchens, restrooms, break rooms, carwashes and any locations that require low-maintenance, washable walls. 

A greenhouse roof is not one size fits all, and effective greenhouse roofing can be achieved through a number of different materials. The most common materials used as greenhouse roofs include glass, polyethylene film, double-layered panels of polycarbonate or acrylic, and fiberglass panels or sheeting. Each of these materials has benefits and drawbacks, and one may be more suited to a particular type of greenhouse than another. Each greenhouse roof material has one very important characteristic in common: It is a clear or semi-clear, light-permeable material that will allow the plants inside the greenhouse to receive the light and heat they need to grow.

Glass roofing does have its drawbacks, though. It generally requires the highest up front cost, not only due to the cost of the glass, but also because it requires strong, sturdy framing materials to support it. Care must be taken to carefully construct and seal glass greenhouse roofs, as those not sealed properly have a high probability of leaking. Glass also carries a higher risk of breakability than some other materials, and it is not the best insulator.

Fiberglass sheets or panels are a long-lasting, less expensive alternative to glass and may be used in permanent greenhouse structures for 15 years or more. This material is much lighter than glass, so it does not require heavy-duty framing the same way that glass roofing does. Fiberglass is durable enough to withstand many types of weather and other outside elements. Over time, however, the light penetration of this material will be reduced; it does require maintenance in order to maintain the best possible light permeability. Fiberglass is also not as flexible as some other types of greenhouse roofing.
