The 4Edge Pro glazing system, the company's most advanced and thermally-efficient solution, secures infill materials on all four sides using unique dry-sealed transom mullions. This cutting-edge technology ensures unmatched weatherability, sleek sightlines and hidden fixings, seamlessly combining the best features of patent glazing with the strength and span capabilities of curtain walling. 

The 4Edge Pro glazing system eliminates the need for additional weathering tapes or silicone sealants, significantly reducing the risk of compromised seals. This innovative design extends the system’s lifespan considerably, especially when compared with sloping curtain walling alternatives. 

Available for single, double and triple glazing applications, the system is versatile and adaptable. 

It is fully compatible with Skyline Box, Skyline, Rafter and Traditional glazing bars, making it an ideal choice for a wide range of architectural designs and requirements.
