It’s award season in the entertainment calendar and The Favourite has come out on top. At Tufwell Glass we’re often asked which is our favourite, toughened glass or laminated glass? We’re here to help you make a first-class choice of glass product for your home or office, so roll the tape as we proudly introduce our stars…
Toughened, or tempered glass is one of the most versatile and durable glass products. Toughened glass is extremely hard to break, in fact it is up to five times as strong as ordinary glass and can endure greater impact or sudden changes in temperature. In the unlikely event that it does shatter, toughened glass crumbles into small rounded pieces which minimise the risk of injury. These features give toughened glass the qualities of a safety glass and explain its popularity in a range of commercial settings. The resilience of toughened glass also makes it a cost-effective choice, adding to its desirability for use in either the home or workplace.
Toughened glass can be transparent or coloured, frosted, printed or painted. It can be cut to any size, though this must occur prior to the tempering process. This process involves passing standard annealed glass through a temperature and time-controlled oven. This takes the glass almost to melting point before its surface is rapidly cooled whilst internally the glass remains hot. This process alters the physical properties of the glass and creates toughened glass. The uses of toughened glass are countless.
Toughened glass is commonly used in glass doors, glass balustrades and glass partitions. It can be used imaginatively to create glass furniture or practically in kitchen glass splashbacks. Just look around your home or workplace and the likelihood is that it has been subtly transformed by toughened glass.
Laminated glass is frequently mistaken for toughened glass (and vice versa), and they are often thought of as being one and the same. Despite both toughened glass and laminated glass being types of safety glass, they differ from in each other in significant ways. Unlike toughened glass, laminated glass has the same strength as ordinary glass; it gains its unique attributes from its double-layered design.
Laminated glass consists of two pieces of glass sandwiched around a plastic interlayer (polyvinyl butyral or PVB). The glass and the PVB are sealed by pressure rollers before being heated. This combination of pressure and heat bonds the PVB to the glass both mechanically – through the adhesiveness of the PVB; and chemically - through bonding of the PVB to the glass. The PVB layer is what allows laminated glass to withstand impact and resist penetration. Though it can break or be punctured, laminated glass will stay intact because of its PVB interlayer which holds together any loose shards of glass whilst preventing cracks from passing from one side of the laminate to the other. Laminated glass is thicker than other types of glass, included toughened glass, and acts as an effective barrier against adverse weather conditions whilst providing better heat insultation, higher levels of UV resistance, and greater sound reduction.
Laminated glass has countless applications and is especially popular for use in shop fronts, skylights, glass doors and windows. Laminated glass can be customised in design through colour applied to the PVB interlayer, making it an attractive and effective product for use in glass shower screens and glass partitions.
