If you want to fix multiwall polycarbonate glazing onto rafters then you need to use one of our rafter gasket glazing systems. These systems are also suitable for installing glass onto rafter based structures.
Our bar systems are supplied pre-packed in 3 metre and 4 metre lengths. Each pack contains a length of aluminium glazing bar cap with glazing gasket pressed in, the TPR rafter gasket and an end plate. On the P501 and P261 systems this is a simple push fit; on the P320 the end plate is an aluminium screw fit style.
The P261 and P320 systems can also be supplied in 6 metre lengths as loose items rather than as pre-packs.
To complete your roof, you will need side trims, U profile end closures, eaves fillers and screws. These can all be seen on the Fixing Accessories page on this website. The Bar Support Systems page shows our versatile aluminium eaves beam and wall plate, both of which can be used to accommodate a range of roof pitches.
