Point Fixing Systems

SPIDER GLASS FIXING

The glazed elements are fixed to a reticulated bolt which via stainless steel spiders fixing directly to the structure. The spider fixing can be fixed directly to a steel structure or to a vertical glass fin. There is often no aluminum grid behind the glass with the only visible support being the flush fitting reticulated stainless steel glass bolts.

CABLE BASED SPIDER GLASS FIXING

Cable facades are, by far, the most artistic and delicate load-bearing constructions for building made of glass. They allow for maximum utilization of light and solar energy, while exhibition great stability spite of being lightweight. Glass, point-holder (spider), load bearing cables and tension ropes from the primary components of a cable-supported facade. The point holders are screwed together with glass panes, which are usually fitted at the glass pane interfaces. The special skills of facade engineers come to bear in connecting tension and load-bearing cables made of stainless steel wires with spreader bars, both easily and in a force-fit manner. At the same time, load-bearing cables hold the weight of the glass, whereas tension cables provide the necessary pull to hold the facade in stable position.

STRUCTURAL GLASS

The vast majority of low to mid-rise curtain walls are installed using Stick system. Long pieces of aluminium (hence the name stick) are inserted between floors vertically and horizontally between vertical members to support and transfer the load of the glass back to structure. Most of the erection and glazing for a stick-built system is done on site. One of the benefits of stick-built systems is it's economic frindliness for facades that have lower required volumes and many complicated conditions. The lead times for these types of systems are often much shorter for fabricated materials to be delivered to the site and allow forlessup front staging. This is shorteren comparison to a utized system, where six months to a year can be required for this process. However, the trade-off is that the installation takes longer to complete on-site. You also need a significant amount of space installation and storage of materials on the site, which can be difficult in many high-traffic cities with tight job sites.
