Laminated Glass


Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. SPG can laminate using PVB, EVA, TPU, POLY and SentryGlas® ionaplast Interlayers in any thickness or combination.

Our Laminating Line


Laminated glass is created through heat and pressure. The heat and pressure can be applied to the glass in several different ways. The most common method for large-scale production is the autoclave method. This method uses an autoclave (a giant pressurized oven) to apply heat and pressure. Autoclaves are extremely costly and complex, and should only be used in large-scale laminating facilities that produce large quantities of the same type of laminate. The alternative, and the future of glass lamination, is the autoclave-free method. 


Always ahead of the curve, SPG has once again proven their industry dominance with the purchase of a Hoaf Autoclave-Free Laminating Line. Having watched autoclave-free systems take Europe by storm over last 3 years, SPG realised there was a huge opportunity to bring a diverse scalable laminated product to Queensland.

Autoclave-free lamination offers three main advantages over an autoclave system that immediately benefit the consumer:


  • Batch-style processing translates to an effortless transition between different laminating interlayers and glass types. Make the laminate work for you by selecting the right laminate for the job. With over a hundred different combinations of glass and laminates, SPG will work with you to make sure you get the right look without compromising safety or durability. SPG can run multiple sizes and types of glass at once for a one-stop shop that covers all your laminate needs.


  • Go green! Large autoclaves require large amounts of steam and electricity to achieve adequate heat and pressure, and divide the laminating process into two energy-consuming steps: de-airing and heating. By contrast, the Hoaf autoclave-free system uses low volumes of natural gas for heat and a small electric vacuum pump to de-air and apply pressure all in one step. Hoaf also incorporates the Smart Blanket System (SBS) which uses reusable silicone vacuum blankets instead of disposable, petroleum-based, vacuum-bagging material.


  • The entire system can be scaled to meet the growing demands of our customers. As customers begin to fully realise the wonderful applications of laminated glass in terms of both safety and decoration, SPG can easily grow to meet the needs of the customer without any down-time in production.
