Patent Glazing Bar System Technical Summary

Specification

Glazing Bars, Cappings, Beads and Fittings are extruded aluminium alloy 6063-T6 to BS 1474. Fasteners provided are either stainless steel to BS EN ISO 3506 Grade A2 or mild steel bright zinc plated. Gaskets are extruded Thermo Plastic Rubber quality to BS 7412.

Performance

All systems are designed to conform with the requirements of BS5516, 1991 when installed within the manufacturer's recommendations. A guide to maximum spans is published in our technical design guide and should be referred to prior to installation.

Fixing

Fixing to timber is directly through the channels at the top of the glazing bars with the two No. 10 x 1 1/2" bright zinc plated wood screws and a sliding shoe with wood screws at the bottom end. Fixing to metal is with M8 Single Hole Fixing Shoes positively fixed at the top and sliding at the bottom end. Dissimilar metals should be isolated to avoid bi-metallic corrosion.

Appearance

Materials are supplied Mill Finish as standard. A range of architectural finishes is available including polyester powder coating to BS 6496 in standard RAL, Syntha Pulvin or BS colour ranges.

Ventilation

May be achieved either through GlazaVent, our top hung roof ventilator, or by casement vents in vertical applications. Various factory fitted opening mechanisms are available including manual, pole or cord operated, electrical, thermostatic or smoke activated controls.

Infill

All popular specifications can be accommodated including 6/7mm Single Glazing, 24mm Double Glazed Sealed Units or 10mm and 16mm Polycarbonate Sheeting. Other infills should be discussed with our technical department. Double Glazed combinations should feature a suitable 'step' to the bottom edge to avoid thermal breaking.
