Glazing Bars

Alukap-XR, Alukap-SS & Snapa Glazing Bar Systems

Glazing bars (sometimes called joiner bars) are used to fix and join roofing sheets onto substructures, such as roofs, canopies and covered areas, providing a waterproof seal between glazing sheets. For almost any type of roof glazing, whether it’s glazed with polycarbonate sheets such as Axiome® multiwall polycarbonate or Axgard® solid polycarbonate, or even single or double-glazed glass units, our manufacturing teams produce a glazing bar system to suit.

Frequently Asked Questions

Snapa Snap Fix Glazing Bar FAQs

Snapa Snap Fix Glazing Bars can be used with a wide range of Axiome Polycarbonate thicknesses including 10mm, 16mm, 25mm and 35mm!

However, when using the bigger thicknesses, especially 35mm, we would recommend using our Alukap-XR system as it is stronger and will secure the thicker, and therefore heavier, sheets better.

Snapa Glazing Bars can be cut to length very easily using any fine tooth saw, such as a hacksaw, jigsaw or circular saw. For best results, care should be taken to ensure a high cutting speed and slow cutting entry speed with a fine tooth blade.

Alukap-XR Rafter Glazing Bar FAQs

Both our Alukap Glazing Bars ranges, XR and SS, are designed to work with any thickness of glass or glazing. Popular glazing types include our Axgard® Glazing Sheets, Axiome Multiwall Sheets, double glazing units.
