Static electricity develops on PVC and tends to attract dust. Rigid panels of PVC are inexpensive, easy to apply, and, when new, have high light transmittance. PVCs' light stability is affected by heat build-up in the panel. If they are carefully applied and partially shaded during hot weather to prevent heat buildup, they will provide good service. Corrugated panels are in sizes up to 24 feet long with widths of 4 feet.
Panels are flexible enough for use with various types of structure.
Life expectancy of FRP is 5 to 10 years, depending on quality. The fibers collect dust and fray, causing the panel to darken. Clear FRP is recommended as a greenhouse covering. To save energy, consider covering your greenhouse with two layers of polyethylene, inflated and separated by a layer of air. This technique reduces heat loss and the amount of fuel used.
