4 Sided Unitised Fully Capped Curtain Walling System

The system currently offers frames for two types of glazed units, a 28mm thick double glazed fixed light unit, and a 28mm double glazed top hung casement. Fixed double glazing incorporates flush edged double glazing units whilst the top hung windows utilise double glazing units that have stepped edges to enable clean and continuous sight lines whilst providing high levels of performance. All fixed double glazed units MUST be dual sealed with a P.I.B. primary seal and a secondary seal.

PRODUCT DETAILS

The Brital unitised 4 sided capped curtain walling system is designed to give an alternative to the structurally glazed and capped Brital curtain walling systems. The unitised curtain walling systems have been growing in popularity and have many advantages over the conventional stick system, particularly for tall building projects. Unitised systems are easy to erect on site and should give faster site programmes. The build quality is improved and the quality of factory manufactured units is easier to control. The glazing/vent frame is retained into the unitised frames by pressure plates fixed at 50mm from each end and at 300mm max centres around the frame using pan headed screws. These then push the glazing/vent frame back against the unitised frame inner gasket to seal the inner faces. The system currently offers frames for two types of glazed units, a 28mm thick double glazed fixed light unit, and a 28mm double glazed top hung casement. Used in conjunction with each other an almost limitless number of permutations can be achieved to suit most architectural requirements. Fixed double glazing incorporates flush edged double glazing units whilst the top hung windows utilise double glazing units that have stepped edges to enable clean and continuous sight lines whilst providing high levels of performance. All fixed double glazed units MUST be dual sealed with a P.I.B. primary seal and a secondary seal. All top hung double glazed units and units at SSG transom MUST be dual sealed with a P.I.B. primary seal and a structural silicone secondary seal suitable for units being placed in SSG applications.
