Things to note

When rafters are at 1070 mm centres no purlins are required (except in high wind areas), giving the most aesthetically pleasing and cost effective structure.  These sheets can be trimmed down to any width to suite existing rafter centers.  Laserlite Multiwall sheets should have a minimum fall of 5 degrees  – this is important to keep your sheets looking good for many years to come.

Silicons are not recommended for Polycarbonate sheeting – the aluminium glazing system is designed so that silicons are not required to be used on the polycarbonate.

Sheets can be cut to length free of charge before dispatch, otherwise a fine tooth circular saw can be used to trim sheets on site.
