Glass Panels

Glass Panels

H&G are suppliers of SentryGlas by Kuraray, a superior laminated glass option originally developed in the 1990s to withstand hurricane windborne debris. SentryGlas is up to 100 times stiffer and five times more tear-resistant than traditional PVB (polyvinyl butyral) interlayers, making it an exceptional choice for structural glass applications. 

Available in ultra-clear and translucent white, SentryGlas offers excellent exposed-edge performance and post-breakage durability. It also filters up to 99% of UV radiation below 380 nm, making it the preferred interlayer for high-performance glass solutions.

Heat Soaking Process

Heat soaking is an essential post-processing step for toughened glass.

In this process, glass panels are placed in special racks within a heat soak oven. The panels are heated to a specific temperature, held at that temperature for several hours and then slowly cooled back to room temperature.

This procedure aims to induce breakage of any panels with nickel sulfide inclusions, thereby reducing the risk of unexpected breakages once the glass is installed.

Heat Strengthening

Heat strengthening involves processing ordinary annealed float glass in a furnace to enhance its strength.

While heat-strengthened glass is about twice as strong as standard annealed glass, it is not classified as Grade A safety glass like toughened glass. Unlike toughened glass, which shatters into small pieces, heat-strengthened glass breaks into larger, less hazardous shards, making it a safer option compared to standard glass.
