Twinfix 500-501 Rafter Glazing System

Installation Instructions

 

Cut rafter gasket and fix to structural rafter (50mm wide) at 300mm centres. If an eaves filler is being used, cut to length to fit between the installed bars and screw fix.

 

Place glazing sheets onto the gaskets. Sheet sizes to be 20mm narrower than glazing bar centres and 12mm shorter than the glazing bar length. Ensure flutes of the polycarbonate are blown free of any dust or swarf and seal each end with breather tape.

 

Secure the glazing cap to the base using the appropriate screws (using plastic cover caps if required) 50mm from each end and 300mm max centres, ensuring screws are not over tightened.

 

At the start and finish of a glazing area, a side trim profile can be used, clamped into the glazing bar. If fitting to a side wall turn the profile with the leg facing upwards, this must then be sealed or dressed with a flashing.

 

Cut ‘U’ profiles to fit between bars, at the top and bottom, and push into place. A bead of polycarbonate compatible silicone can be applied to the upper side of the sheet where it meets the U-profile. Once in place repeat 1 to 5 for other glazing bars.

 

Push fit the plastic end plate in place ensuring it is fully clipped into the correct position to complete the system.
