Capping Glazing Bar
Capping Bars are used to fix glazing sheet to wooden rafters. The manufacturing guidelines for fixing Marlon Multi-wall Sheet states that rafters should be at least 700mm apart.
RAG gasket is fixed to the rafter using pins/small nails and then the edges of two sheets meet on top. The gap between sheets should be at least 10-15mm apart to allow for thermal expansion. The capping bar sits over the join of the two sheets and is screwed down from above, fixing the capping bar to the rafter and clamping both sheets in the process.
The same capping bars are used in the installation of Multi-wall sheet are also used in the installation of flat sheet polycarbonate.
Capex bars are available in WHITE or BROWN, in widths of 40mm or 60mm and in lengths of 3.0, 4.8 and 6.0mtrs.
