Glass Fins Walls
The glass fin (mullion) is the original backup structure first introduced by Pilkington over 40 years ago. Today, it is still the most widely specified support member in structural glass design.
These fin supported systems exploit the full potential of glass as a structural material while providing support for the Pilkington Planar™ glass facades and fin walls for maximum transparency.
The glass fin wall system uses monolithic or laminated fully tempered glass fins as a means of support to transfer wind loading to structure. Various "moment" and "pin" type connections can be used to transfer loads to the structure in different ways.
Most structural glass fin supported structures are suspended from the structure above. Pilkington Planar™ glass panels are fastened to the glass fins by the use of Pilkington Planar™ fittings. In this arrangement, the total weight of the facade panels and fins is carried by the connection at the head. This design allows for very high facades to be designed without large in-plane loads on the Pilkington Planar™ panels. While some systems can be floor loaded or "stacked", we will ONLY floor load up to a height of 32 feet (10 meters). This configuration is due to the possible buckling of the glass fins. In high seismic areas, glass is always suspended. All glass fin back-up structures are available as a completely engineered sole source Pilkington Planar™ system package for guaranteed performance of the complete assembly.
There are many variations and options for structural glass fin wall designs available depending on the design intent and structure available. Please consult a W&W Glass architectural design specialist for specific application recommendations.
Laminated Pilkington Planar™ structural glass is ideally suited for horizontal applications such as glass canopies. Glass panels are typically bonded together with "SentryGlas®" ionoplast interlayer from Kuraray* laminate, which allows the architect to have completely exposed edges without worrying about long-term edge stability concerns from exposure to moisture like with PVB interlayers. The glass panels can be silk-screened in any Pilkington standard or custom pattern before being laminated. Virtually any design can be accommodated with digital-printing technology now available for Pilkington Planar™ glass. For more information on SentryGlas® ionoplast interlayer from Kuraray*.
The inherent design flexibility of Pilkington Planar makes it an excellent system for structural glass canopy and roof applications. Exterior framing, that can become a maintenance problem or possibly cause future leaks, is not required. The backup glass canopy structure is required to carry self-weight, snow loads (where applicable), and to resist negative wind pressures through fixing locations. Large spans are possible if underlying purlins are reinforced with cable or tension rod rigging. Laminated glass beam purlins are also an options for ultimate transparency. In some cases, Pilkington Planar™ glass canopies can even be supported by laminated structural glass fin vertical walls. Pilkington Planar™ canopies require a minimum slope of 3 degrees to eliminate ponding on the glass.
W&W Glass are the only authorized glass canopy system suppliers who also make all backup canopy structures available as a completely engineered, sole source package for guaranteed performance of the complete Pilkington Planar canopy system.

Glass On Steel Substructures
Architects and owners are increasingly interested in incorporating new glass designs in steel as a backup structure to Pilkington Planar™.
Pilkington Planar™ structural glass can be coordinated with all types of steel structures, ranging from simple pipe columns to complex truss systems. Steel structures with Pilkington Planar™ can be used either vertically or in roofs and skylights. These structures can be internal or external to the glass plane.
W&W Glass can supply the entire backup structure in addition to the Pilkington Planar™ System as part of a sole source design/build package, or we will happy to coordinate with steel contractors to insure the correct end product. Contact our team of design consultants to help with your project.
Cable Nets and Tension Trusses
When architects and engineers are looking to create long spans of structural glass in a building design, the use of cable net and tension trusses allows for greater design flexibility and creativity. W&W Glass has extensive experience working with these methods to execute complex structural glass designs.
The cable net wall offers the thinnest, most transparent solution for minimally supported glass applications. For almost 20 years, the cable net has offered architects and engineers the ability to span great distances without the need for large, heavy-structured elements within the glazed area.
Cable nets can be one-way or two-way nets – spanning either vertical only or vertical and horizontal. Structural Glass panels of almost any configuration can be used to enclose the space. They are mounted by the use of countersunk Pilkington Planar™ bolt assemblies or custom patch fitting clamps made of steel, stainless steel, or aluminum.
Various forms of cable-stayed tension structures can be used to support a Pilkington Planar™ facade. They can take the form of simple strong back steel trusses, bow-string trusses, or lighter weight, more filigree cable trusses. Designers have complete freedom and flexibility when designing these trusses. These structures can be internal or external to the glass plane. They are often used to keep the structure as transparent as possible, while requiring lower tension loads on the boundary support structure than a cable net wall. Tension trusses can be supplied by W&W Glass as part of a single source Pilkington Planar™ solution with glass and fittings.
There are many variations and options for cable nets and tensions trusses available depending on the design intent and structure available. Please consult a W&W Glass architectural design specialist for specific application recommendations.
Hybrid Tension Rod/Steel Beam Facades
A tension rod/steel beam system is a hybrid design between a cable net wall and a full steel substructure. This type of glass configuration allows horizontal steel plate beams or tubes to span across an opening (often pinned back to structural steel columns 20-40 feet on center) to act as a wind load brace. They are often pinned back to structural steel columns 20-40 feet on center. For this configuration, vertical tension rods or cables (connected to the front of the horizontal beams) support the dead load of the glass with Pilkington Planar™ countersunk fittings or custom patch fittings. The vertical rods/cables with fittings connect to the horizontal steel to pick up the sag between column supports as well.
This system couples a minimal support structure, designed for a high level of transparency, with a low tension loading impact on the boundary structure. Various types of glass structures can be created incorporating tension rods, cables, simple tubes, or pipes designed in numerous configurations to support the Pilkington Planar™ façade.
W&W Glass can supply the backup structure along with the Pilkington Planar™ system as a complete design/build product.

Glass Roofs and Skylights
The inherent design flexibility of Pilkington Planar™ is ideally suited to roof applications. Framing, that can become a maintenance problem or possibly cause future leaks, is not required. Pilkington Planar™ glass carries self-weight, snow loads, accommodates seismic movements, and resists wind pressures through the use of Pilkington Planar™ fittings.
Large structural glass spans are possible if underlying purlins are reinforced with cable or tension rod rigging. Pilkington Planar™ glass can also be supported by tension trusses, laminated glass beam purlins, space frames, and many other types of structures. The structure can be located above or below the glass. Pilkington Planar™ roofs require a minimum slope of 3 degrees to eliminate ponding on the glass.
Various glass types can be incorporated into the roof or skylight for superior performance. All glass is laminated, generally using SentryGlas® ionoplast interlayer from Kuraray* laminate. For more information on SentryGlas® ionoplast interlayer from Kuraray*.
All backup structures are available as a completely engineered sole source package for guaranteed performance of the glass roofs and skylights.
