Structural Glazed Curtain Wall
As of late, this system has gained popularity as viable replacement to the traditional silicone facade system. Glass is safely secured in place by virtue of a specialised clips inserted into the glazing slats called tougle both vertically and horizontally to the underlying profile structure. The grout between the glazing is then filled and sealed with silicone. This method was developed as a more economical alternative to the structural silicone system, as the costs associated with frames and bonding processes are hereby eliminated.
Fully Capped Curtain Wall
With this system the glass is fastened to vertical and horizontal profiles with pressure strips. As all sides are linearly supported this is a more statically sound alternative for the glass panels. Servicing and replacement of the individual glass panels is done by removing and subsequently re-fastening of the relevant pressure strips and capping materials. Special architecural effects can be attained by using alternately sized profiles.
Semi-capped curtain walls
The glass is only visibly fastened to the external building structure with pressure strips on one axis only. The other remaining axis is fastened in accordance with project’s desired cladding profile with clips. Mostly, this system is used to lend to the structure either vertical or horizontal accents. Many capping alternatives are available to be used in these solutions; like almond shaped, box cut, classic caps, etc.
Structural Silicone – Framed Systems
Structural silicone framed systems These are the first silicone glass facade systems applied to buildings. The glass panels are bonded to pre-prepared aluminium frame structures using specialised constructive silicones. After observing the necessary curing period, panels are moved on site and “hung/suspended” in place off of the horizontal profiles. The grout has EPDM tampons.
Panel Cladding
This system is different in that it involves the hanging of prefabricated (in a factory) glass panels onto special anchorage system directly attached to the concrete substructure of the building. in comparison to capped wall system, this method necessitates the employment of considerably fewer assembly staff and is usually completed in shorter time. However, the fabrication process does incur greater costs and prerequisite system details, as well as some limitations. generally some measure of custom design profiles are required for the implementation of this solution. This method is especially valued for larger scale projects with considerable time constraints. When decided upon at the project phase, the assembly of the superstructure can be synchronised with the erection of the concrete substructure. These panel systems also provide added seismic resilience.
Transparent Curtain Wall Systems
These systems are preferred when a “grid effect” on the facade is specifically not desired. Heat insulated or single laminated glazing is fastened to the substructure through a combination of spider holders and either ball joints through pre-cut holes in the glass or special stainless claps extended through the grouting. The points where the panels join with the substructure are fabricated with moving joints, thus allowing for the stresses on the glass to be effortlessly transferred to the substructure. After the initial install, the grout is filled with silicone thus achieving waterproofing. The substructure can be chosen out of a multitude of materials and shapes; like stainless or plain steel profiles, stainless rod or spans, glass column, special stainless consoles, etc
