Fittings
Using specially designed Planar fittings, insulated or laminated glass panels are fastened back to building structures by the use of highly engineered and tested bolts that are countersunk into the glass to allow a flush exterior surface. Only the most durable and highest specification components are used.

Planar fittings are made of austenitic stainless steel type 316. Lesser grade alloys may deteriorate under certain environmental conditions. Spring plates that transfer load between Planar fittings and structure may be aluminum alloy or other suitable metals such as stainless steel, galvanized mild steel or powder coated steel.

Star or Spider Type Castings

Four point and two point castings represent only some on the many types of stainless steel connectors designed to connect the glass fitting back to the back-up structure. The Star/Spider connectors shown here are 316 grade solid stainless steel lost wax investment castings. Other forms and shapes are available.

Planetarium Casting

The Planetarium Casting represents one of the most sophisticated stainless steel castings available. Designed to accommodate large lateral movements by the use of an adjustable arm, it maintains an extremely flat profile.

IBT-Segerstrom Casting

This unique stainless steel casting is designed with sliding arms to accommodate large racking displacement of the glass under severe seismic events. This fitting allows for movement of up to 1" in two directions at each glass joint.

Anti-buckling Fin Technology

Developed through extensive testing by Pilkington, anti-buckling fin technology was developed to allow designers to have longer fins, wider modules, and work with higher windloads. Anti-buckling rods are 1/4” diameter stainless steel tension rods bolted to the back edges of the glass fins to provide lateral support preventing the fin from buckling or flipping out of plane during load. Extensive testing for projects in Asia, where windloads were 250 psf, led to Pilkingtons innovation in this technology. This technology gives the architect the ability to design and Pilkington to provide soaring glass facades with minimal additional structural support over and above the glass fin itself.

905 and 905J Fittings

The 905 is the most popular fitting in the Planar range. The 905J fastens to glass fins while the 905 fastens to other types of structures. The 905 eliminates the need for spring plates and allows absorption of live loads and thermal expansion through rotation around a steel pin connected to the backup structure. The 905 is available in a design to accommodate Zone 4 seismic movement.

902 Fitting

The 902 fitting fixes directly to the secondary structure by means of Planar spring plate brackets. They can be fastened to a variety of support structures such as glasss fins, metal mullions, space frames, cable tension assemblies and rigging structures. The 902 can accommodate any angle of slope from vertical to horizontal, making it suitable for glass roofs and canopies.

Integrated Fitting Design

A fully tested and patented method of fixing laminated glass panels to a backup structure with no exterior bolts, caps or washers.

All fixings are concealed within the laminated glass. This fixing system allows for a much wider variety of glass types including art and textured glass to be used in a structural glass application.

The integral fitting allows us to horizontally glaze an entire roof or canopy with absolutely no visible exterior fasteners.
