The use of structural glazing in commercial buildings has increased in line with architects’ and clients’ vision and desire for ever more creative and eye-catching building facades. The most popular method of manufacturing these units is to bond the glazing to the frame using structural silicone Structural glazing is a system of bonding glass to an aluminum frame of curtain wall utilizing a high-strength, high-performance silicone sealant. These silicone sealants are specifically designed and tested for structural glazing. In this dynamic wind loads are transferred from the glass, by the structural silicone sealant, to the perimeter structural support.
In this system there will not be any aluminum member visible from outside. You will see a groove running horizontally & vertically. In this system the glass is held with the help of structural sealant.
It increases the thermal efficiency of buildings because the exterior exposure of metal framing is either reduced or eliminated, It reduces or eliminates water and air infiltration,
It reduces the potential for thermal breakage of glass.
