If you want to fix multiwall polycarbonate glazing on to a roof without installing rafters then you need to use one of our structural glazing bar systems. Some of these systems can also be used for installing polycarbonate, both multiwall and solid, in vertical applications.
We have systems capable of spanning up to 4000mm between fixing points. Our P288, P280, P284 and P227 systems are also suitable for securing glass, although spans and centres would be greatly reduced.
The P280, P288 and P227 aluminium bar systems are supplied pre-packed in 3 metre and 4 metre lengths. Each pack contains a length of aluminium glazing bar cap, an aluminium base with glazing gasket pressed in and a screw fit end plate. The P284 and P288U systems have an additional uPVC thermal underclad fitted to a mill finish aluminium base. All our aluminium caps are fixed to their base bars with stainless steel screws in order to securely hold the polycarbonate glazing in place.
P280, P284, P288 and P227 systems can also be supplied in 6 metre lengths as loose items.
The P600 system is supplied in 2.5 metre, 3 metre, 3.5 metre and 4 metre pre-packed lengths only and consists of a mill finish aluminium base bar with white uPVC thermal underclad fitted, a white uPVC snap-fit cap and a screw fit end plate.
With the exception of the P600 system that is available in white only, our aluminium structural glazing bars are supplied in mill finish, white and brown. The mill finish bars can be powder coated to any specified RAL colour. However, please note that we can only supply the uPVC thermal underclads in white or brown.
