Polycarbonate Glazing Bar Systems - An Overview

Take a look at our brief overview into the main Polycarbonate Glazing Bar Systems and their respective features & benefits.

Rafter Supported Glazing Bars

A cost effective roof glazing bar, ideal for lean-tos, shelters etc. Easily fitted – a heavy duty aluminium base section is fitted to a continuous rafter (timber or metal). Polycarbonate is then laid between the bars and the Top cap (UV stable) is clicked down into position to suit the glazing thickness. Suitable for polycarbonate 10, 16 & 25mm thick. Includes gasket.

Screw Down Glazing Bars

A superior roof glazing bar, typically used for timber conservatories and other timber glazed structures, canopies and lean-tos. Easily fitted – a rubber gasket is laid on a continuous rafter (timber or metal). Glazing is then laid on the rafters and the aluminium glazing bar is fixed down, clamping the glazing between the bar and the rafter. Suitable for any thickness glazing. All bars (and other components) include gasket.

Self-Support Glazing Bars

A self supporting glazing bar, typically used for lean-tos, conservatory roofs, canopies and carports. Easily fitted – a wall plate is fixed to the wall and an eavesbeam fixed at the front of the roof (on windows, posts etc). Glazing bars (max unsupported projection of 4m) are then fixed between the two, set at the correct centres. Polycarbonate or glass is then placed between the bars and the PVC top cap clicked down into position. Suitable for 16, 25, 32 & 35mm thick glazing. Includes co-extruded gasket.

Snapa Lean-To Bars

An easy-to-install glazing bar featuring click-connection points that allow it to be connected to a variety of sheet thicknesses. Polycarbonate sheets are clipped in on either side and kept secure by the high quality extruded walls of the bar. This bar is compatible with 10mm, 16mm, 25mm, 32mm & 35mm Axiome polycarbonate sheets.

Snapa Gable Bars

Featuring all of the qualities of the Snapa lean-to bar, the gable bar is designed for finishing off the final rafter on a polycarbonate roof. Historically it has always been difficult to complete this task, and even more difficult to make it look good. This is no longer an issue with the Snapa gable bar, which provides a fast and easy method of installing the last glazing bar with a snap fix connection as well as a waterproof seal. This bar is compatible with 10mm, 16mm, 25mm, 32mm & 35mm Axiome polycarbonate sheets.

Snapa End Cap

A simple screw on end cap for Snapa lean-to and gable bars to provide a most aesthetically pleasing finish. Lean-to and gable bars are supplied with a free end cap.

Snapa H Section

These trims are used to create a strong connection between polycarbonate sheets on timber rafters at the top and bottom and ensure a long-lasting glazing project and are compatible with Axiome 6mm, 10mm and 16mm polycarbonate sheets.

Snapa C Section

Snapa C sections are used for sealing and protecting the ends of 10mm & 16mm Axiome polycarbonate sheets. This trim should be used in conjunction with a low modulus silicone sealant (applied to the inner surfaces of the trim) in order to create a weatherproof seal.

Drip Trim

Snapa PVC drip trims are used to clip along the width of a polycarbonate sheet and create a waterproof fitting. They are compatible with Axiome polycarbonate sheets of 10mm, 16mm, 25mm & 35mm thicknesses. drip trims are perfect for DIY projects such as carports, canopies, and conservatory roofs. All Snapa PVC drip trims are supplied in a 2100mm length.
