Things to note


When rafters are at 1000 mm centres no purlins are required (except in high wind areas), giving the most aesthetically pleasing and cost effective structure.


Silicones are not recommended for Polycarbonate sheeting.


Sheets can be cut to length free of charge before dispatch; otherwise a fine tooth circular saw can be used.
