Structural glazing sealants must conform to the strictest strength, durability, and weatherability standards. Structural glazing techniques are based on highly demanding specifications and application methods.
Each distinct application of structural glazing requires great attention to detail in the design and manufacturing of the glazing system, as each building differs in terms of the characteristics of its environment, the particular weather conditions that apply in its vicinity, as well as its exposure to daylight and wind.
VASGLASS, adheres to this philosophy and through its resident team of architects and engineers is prepared to design and implement special glazing solutions for highly demanding applications of any scope (thermal insulation, solar control, etc.).
The term “structural glazing” denotes the use of glass as a component of the building envelope by bonding glass to a building’s structural framing members, whereby the glass supporting structure is hidden or is slightly visible. It comprises of a vertical lightweight outer structure designed to bear its own load and the loads typically resulting from wind forces.
The four main structural glazing systems:
Conventional Structural Glazing (using pressure plates)
The most widely and the longer applied type of structural glazing. The architectural glass panes are held in position by means of pressure plate framing. The glass panes are mechanically fastened on the outer part of the frame while they are sealed together using a polysulfide polymer sealant.
Semi-conventional Structural Glazing (without use of pressure plates)
Structural support of glass is achieved through a specially designed aluminum profile which is attached to the frame of the building. The thinly designed aluminum profile allows for a minimal visual footprint of the supporting structure, which substantially differentiates it from the conventional structural glazing system.
Structural Spacer Glazing
In this method, the aluminum profile is fully concealed from the outside of the building. The safety glass pane is mechanically fastened on the specially designed aluminum profile using structural silicone.
Structural Silicone Glazing
Structural support of glass is not provided by mechanical means, but rather by using structural silicone as sealant on all four sides of the metal curtain wall framing system. Glass is the only material visible on the outside of the building.
