Structural glazing is a now the latest trend which all most all the big multinational has taken over to improve the performance of the building. With structural glazing we have better day light and climate control system in the buildings. The material generally used to make structural glazing includes glass, aluminium, silicone sealant and ethylene propylene Di amine monomer. Some of the commonly used glazing system includes curtain walling, structural glazing, bolted glazing, fin supported glazing, cable stayed glazing and suspended glazing.
When we are using glass as curtain wall in the building it can be made up of lightweight material reducing construction coat and allowing natural lights that can penetrate much deeper. Actually structural glazing is the system of bonding to an aluminium frame utilizing a high strengthens high performance silicone sealant. This technique can be used with almost all types of glasses including insulating glass units. Some of the basic accessories required for structural glazing include mullions or vertical members provided basically to transfer the dead load of curtain wall. Transoms or vertical members include aluminium section which is provided between the mullions. Another very important accessory includes the silicone sealant which is used to prevent the passage of moisture, air dust and heat through all the joints. Finally there are setting block and location blocks which provide support in relation to the glass, glazing techniques and condition of use. The location blocks prevent the movement of the glass within the frame.
Bolted glazing is a technique which is less obstructive in nature. This traditional system consists of attaching the glass panels and the structure with rigid bolts. The modern system uses knuckled bolt for fixing of the glass instead of the common fixed bolt. Another type which has a great hype in the market includes glass fin supported glazing which allows greater visibility and increases the natural light in the interiors.
