These 4mm structured polycarbonate sheets are perfect for greenhouse glass replacements. Polycarbonate is up to 200 X stronger than the equivalent in glass and does not shatter so provides a safe environment for your children. The panels are 1220 x 610mm (4' x 2') and can be easily trimmed to fit where required using simple fine tooth saws, hacksaws or trimming knifes.
Sold in packs of 10 these make the perfect low cost alternative to glass.
