Lexan is a polycarbonate sheet
with UV protection used for greenhouse coverings. Lexan is also used in
skylights and covered walkways. It is inexpensive and transmits up to 90 per
cent of available light throughout the greenhouse. It is impact resistant and
durable, with more than 20 times the resistance of fibreglass and 40 times that
of glass, protecting from hail, wind and other flying objects with 109 Kilogram
of impact. Sheets of Lexan can be purchased in grey, bronze and opal to reduce
the brightness and heat inside greenhouses. Lexan can be installed easily with
woodworking tools and come in sheets that are 8 to 40 feet long by 27 to 51
inches wide.
