STRUCTURAL GLAZING OF REQUISITE TYPES

Structurally glazed systems create a greater transparency than traditional captured systems.

STRUCTURAL GLAZING OF REQUISITE TYPES

Structural glazing systems, in their simplest form, are types of curtain wall systems consisting of glass that is bonded or anchored back to a structure without the use of continuously gasketed aluminum pressure plates or caps. The glass can be comprised of monolithic, laminated, dual-glazed or even triple-glazed insulating glass units (IGUs). The back-up structure may use horizontal and/or vertical aluminum mullions or be a glass mullion, steel blade, cable or stainless steel rod. The interior and exterior may use extruded silicone/EPDM gaskets, or a wet sealed silicone depending on the system. This system creates a completely clean, flush exterior appearance while the interior members have many different options depending on design and budget.
So why would you want to go with a structural glazing system? Structurally glazed systems create a greater transparency than traditional captured systems. There are less visual interruptions due to the lack of metal on the exterior (and potentially the interior), creating a seamless, continuous glass look. Traditional captured curtain wall systems have pressure plates and caps that can conduct large amounts of heat in or out of the fa├žade depending on the season. Since there is little to no exposed exterior metal, there is also less thermal bridging with structural glazing, saving on energy consumption costs. Now, let's take a look at some of the different types of structural glazing systems in the market today.

Four Sided Framed Glazing:

In four sided framed glazing a frame is fabricated on all four sides of the glass to support it. During installation the horizontal and vertical support members are framed on the building. Glass is used as a transparent infill panel.

Two Sided Framed Glazing:

In a two sided framed glazing the support for glass is only on two sides. It is either fabricated in the horizontal or in the vertical direction. The glass is then fixed in the mullions.

Frameless Glazing:

The frameless glazing imparts a seamless look to the glass. The glass is fit together with different kinds of hardware like spider glass etc., which are used to tie the glass to the structure.

Glass Fin Glazing:

Glass fins are vertical glass sheets used to strengthen the glass facade. The glass sheet is placed in a perpendicular direction to the building facade. It is bonded to the building with special hardware and silicon sealants. The Sealants that are used in structural glazing have to be strong, durable and be resistant to ultra violet radiation. They should also be neutral to changing weather conditions since glass may get over-heated in summer and there might be heat loss in winters.

SINGLE & DOUBLE GLAZED UNITS

A single glazed window is constructed using a single pane of glass. This means that the only thing separating your home from the outside environment, is that pane of glass. Typical window glass ranges from 3mm to 10mm, which doesn't provide adequate insulation. A single glazed window can be up to 20 times less efficient than an insulated wall when it comes to energy loss or storage.

VISION & SPANDREL PANELS FITTED WITH REFLECTIVE/TINTED/CLEAR/INSULATED THERMAL

There are a wide range of glasses to choose from to meet the needs of any project. Spandrel glass is one such option.Unlike vision glass, which is meant to be transparent, spandrel glass is designed to be opaque in order to help hide features between the floors of a building, including vents, wires, slab ends and mechanical equipment.

FRAMELESS GLAZING VIZ., SPIDER AND PATCH FITTINGS

frameless glass concept, which evolved as modern interior and exterior design option for commercial and residential projects. Patch fittings concepts are a collaboration of toughened glass and glass architectural hardware. Patch fittings frameless concepts have various types like frameless glass doors, frameless fixed glass, Over panel glass with different design options like top and bottom patch fittings, top patch fittings bottom insert and top and bottom inserted to the floor and roof respectively.

Other glazing systems

  • Frameless glazing systems: In these systems silicon joint sealants play an important role in the protection of joints exposed to atmospheric effects, as well against moisture penetration and for insulation of glass panels.
  • Structural bracing of non-glass materials: Structural silicone joint sealant can be used not only for fastening glass materials. It can also be applied for fixing aluminium composites, metal panels, thin epoxy sealed panels of pebble gravel.
  • Shock resistant glazing : Structural silicone joint sealant strongly fixes the laminose glass in the frame during adverse environment conditions (explosion, storm, earthquake, natural cataclysms).
