What Is Structural Glazing? Everything You Need To Know
Nowadays, structural glazing of facade is increasingly used for cladding the facades of private houses, as well as in the construction and reconstruction of public buildings, shopping malls, shops, business centers.
Structural glazing of facades is the latest technology for fastening double-glazed windows, which allows you to create a single surface of glass without any visible clamping elements.

This technology allows architects to realize their most refined projects. With this modern facade, any building looks elegant and stylish.

Thanks to the structural glazing, the edge of the enclosing structure is erased, allowing large amounts of sunlight to penetrate inside. Due to the lack of visible fasteners, the facade of the building looks monolithic without gaps and gaps, which makes it less polluted and clogged with dust.
Structural facades are as good as ordinary facades in terms of their soundproofing properties, thermal conductivity characteristics, water-resistance and durability.
As a bearing structure in the structural glazing of facades silicone sealant is used. It protects the facade elements from atmospheric and mechanical influences and makes the structure airtight.

When properly installed and properly designed, the silicone sealant prevents glass from shifting, chipping, as well as opposing wind, rain and other atmospheric precipitation.

Silicone sealant is used for bonding glass and the frame of the building. In addition to glass sealant can be glued metal, stone, ceramic or composite panels. The sealant can be in facade color or colorless.

Silicone sealants for structural glazing are produced by Dow Corning, Tremco illbruck, UltraGlaze, Sikasil and many others. Silicone sealants of these brands have excellent performance and can easily withstand temperature fluctuations from -30 to +40 C.

The device of structural glazing
For structural glazing, double-glazed windows are attached to the silicone sealant in two ways: double-sided and quadrupled.

Double-sided fixing is carried out in the following way: vertical and horizontal fixing elements are attached to the supporting structure.

The structural silicone sealant is subjected to a mobile load that is distributed on two sides. Mechanical fasteners accept the load on the other two sides.

With the four-sided method of fastening, all sides of the glazing unit are glued together using the sealant. Depending on the project, the dead weight of the structure can be absorbed either by the supporting ribs or by a silicone layer.

Special requirements are placed on the structural glazing of the facade, which must ensure the absolute rigidity of the frame. Prior to the start of work, the structure is processed so that there are minimum joints between the glasses of size 1-2 cm, which are necessary to compensate for temperature fluctuations. Deflections of the floor slabs are not permitted.
    The main feature of structural glazing is the absence of mechanical fasteners, as the supporting structure is silicone sealant. The distance between the glazing units does not exceed two centimeters and thanks to the uniform colour, the impression of a monolithic facade made of solid glass is created.

    An important feature of structural glazing is the special glass units, which have glass of different sizes. Thus, the outer glass in them is longer than the inner glass, so that both glasses are simultaneously glued to the support frame, thus increasing the strength of the structure.

    Typically, tempered glass is used on the outside and triplex on the inside.

    Advantages of structural glazing
    Thanks to the transparent design of the structural facade, more natural light penetrate into the room and the building acquires a light modern appearance.

    The structural glazing has high safety performance and is resistant to UV rays, precipitation, and mechanical influences.

    Operation of the structural facade is simple and convenient. Thanks to the seamless connection between the glasses, no dirt accumulates and the facade is always clean.
