If there’s one thing that symbolises Christmas shopping, it’s the Christmas window display. From Selfridges in London to Fenwick’s in Newcastle, shoppers delight at the festive fronts created for their viewing pleasure. For most, it’s what’s behind the glass that is the focus, but for those of us with a professional interest the unsung star of the show is the glass itself. And so, we pay seasonal homage to laminated glass.
Laminated glass is a type of safety glass. It consists of two pieces of glass sandwiched around a plastic interlayer of polyvinyl butyral or PVB. In the glass manufacturing process, the glass and PVB are sealed by pressure rollers before being heated. Laminated glass has countless applications including skylights, car windscreens and glass doors. It is especially popular for use in shop fronts for the following reasons.
Glass transmits light. This is usually regarded as one of its attributes, but when that light is ultra violet (UV) it can fade interiors – undesirable for retail stock. The PVB layer within laminated glass can block almost all UV rays that try to pass through the glazing – 99% in fact; meaning that products on the other side of laminated glass will experience minimum fading and retain retail value.
The PVB membrane in laminated glass also serves to block sound waves and reduce vibration – particularly useful for noisy urban settings where retail outlets are often situated. Different glazing thicknesses and membrane combinations can be utilised depending on the prominence of nuisance noise, so that the finished laminated glass product serves to enhance the retail environment.
In the same way that laminated glass can block out noise, it can act as an effective barrier against adverse weather conditions. Laminated glass is thicker than other varieties of glass, such as toughened glass, and acts as a protective barrier against strong winds and heavy rain. Laminated glass also offers great thermal insulation properties which can lead to potential savings in heating and cooling costs. This benefit can be enhanced further with the use of tinted glass.
Laminated glass can withstand impact and resist penetration – an important consideration for any business with valuable stock. Though it be punctured or break, laminated glass will stay intact because of its PVB interlayer. The PVB holds together any loose shards of glass whilst preventing cracks from passing from one side of the laminate to the other. This creates a high level of security as well as safety.
So, as you marvel at shop window displays this festive season, take a moment to appreciate the laminated glass through which you view them, and contact Tufwell Glass on 01293 533 533 or at email@example.com to find out more about our laminated glass range.
