Structural Glazing

Structural glazing systems incorporating spacers and adhesives are now a widely accepted glazing option and are used in a growing share of curtain wall, window and storefront installations.

In fact, many people have come to regard structural glazing as the superior method of glazing. When properly installed, the structural sealant forms a continuous, waterproof seal against leakage and air infiltration. The sealant and spacer transmit wind load movement to the structure and withstand flexure, tension, compression and differential thermal shear stresses. Silicone resists UV, ozone and other environmental exposures and does not take on a compression set or lose resiliency. While structural sealants generally carry a 20-year of exposure still demonstrate elasticity, adhesion and strength.

The major issues that govern the design of structural glazing systems are sealant performance air and water infiltration, structural design requirements, and the use of right type of glass. These requirements directly affect aluminium profile sizes, sealant widths and join sizes.
