Structural Glazing Mastic Sealants

Sealing & bonding on glass structures without mechanical fixings 

Structural glazing mastic sealants play a crucial role in the construction and installation of modern structural glazing systems used in construction. Whether it be at factory production stage or in-situ on an existing structure, all structural glazing involves the use of glass or other transparent sheet materials held in frameworks in the fenstration (opening) of a building to allow light in from the outside. Used extensively in both interior frames and exterior facades of various types of buildings, structural glazing mastic sealants are specifically ...

Sealing & bonding on glass structures without mechanical fixings 

Structural glazing mastic sealants play a crucial role in the construction and installation of modern structural glazing systems used in construction. Whether it be at factory production stage or in-situ on an existing structure, all structural glazing involves the use of glass or other transparent sheet materials held in frameworks in the fenstration (opening) of a building to allow light in from the outside. Used extensively in both interior frames and exterior facades of various types of buildings, structural glazing mastic sealants are specifically designed, tested and certified to provide and ensure a very strong bond between the glass (or other) panels and the supporting frame or structure in the system as well as helping to weatherproof the connection joints from light to extreme weather conditions through the different seasons.

The movement capability and high degree of elasticity of structural glazing mastic sealants is specifically formulated to accommodate structural movements, thermal expansion and contraction, and other dynamic forces that may affect the building. This flexibility helps prevent common sealing & bonding failures such as cracking and splitting, ensuring the bond and/or seal maintains its integrity over time. With maintenance, cosmetic repairs and general lifespan being a major consideration of a structural glazing system, (especially when the structure is particularly tall) it's crucial that the correct structural glazing mastic sealants are specified and utilised wisely for longevity, cost-effectiveness and most importantly to adhere to the governing standards and certification.
