4Edge Pro

The 4Edge Pro glazing system is our latest, highly efficient roof glazing solution, known for its thermal efficiency, weatherability and modern design.

This proprietary system secures infill materials on all four sides using dry-sealed transom mullions, offering enhanced weatherability, slim sightlines and concealed fixings, similar to patent glazing, while also providing the strength and span capabilities of curtain walling. Unlike other systems requiring additional weathering tapes or silicone sealants, the 4Edge Pro features a unique transom connection that fully drains into the glazing bars, eliminating secondary seals and reducing the risk of seal compromise. Additionally, the in-line transom cap’s slender design effectively reduces unsightly tide water marks, unlike competitor alternatives that hold water.

Available in single, double and triple glazing applications, it is compatible with various glazing bars, ensuring superior performance and extended lifespan. Its aesthetic appeal is further enhanced by the choice of plain or ornate snap-on cappings that conceal fixing screws, providing a robust and fully drained glazing solution.

Heritage

Our Heritage lead covered steel patent glazing bars embody the essence of the patent glazing tradition, dating back to Victorian innovation. The glazing bar features a galvanised steel core encased in a seamless lead extrusion covering, incorporating a twin wing weathering system and glass seatings. Ends are hermetically sealed, completed with cast brass fixing plates and glass stops.

While some competitors market their modern aluminium systems as heritage alternatives, our Heritage patent glazing system is the only true heritage product on the market, unaltered since the Victorian era.

This system is perfect for replacing, refurbishing and upgrading Grade 1 & 2 listed buildings, historic buildings and other prestigious projects. No other products on the market match the original lead covered steel patent glazing bar.
