Stairs are a standard part of modern constructions with the emphasis on storeyed buildings. They are however not the same age-old stairs from times past. Stair balustrades are not just a safety feature anymore but also a focus of interior décor.
A frameless glass balustrade is an ideal choice for interior décor enthusiasts. So as not to compromise the safety of your balustrade, use of glazed glass is required. The standard type of glazed glass used for balustrades is laminated glass. This consists of two bonded glass panes with an interlayer which holds glass shards in case of impact. Here are some of the common interlayers used in laminated glass.
Polyvinyl Butyral (PVB)
This is the most common interlayer used for glass balustrades. It is relatively cheap, durable, has excellent detail and comes in various colours, tints, and patterns. Some companies have PVB hybrid glass which includes a polyethene terephthalate layer to enhance its performance.
Cast In Place (CIP)
Rather than an interlayer sheet, CIP is a poured resin. It is poured between two panes then left to cure. Though cheaper than other interlayers for laminated glass, it does not offer high performance. CIP is also not very durable and its finish at times looks messy necessitating the need for concealing tape on its edges.
Ethylene Vinyl Acetate (EVA)
This is not a common interlayer option. It is quite expensive but offers the highest aesthetic value. You can use EVA interlayers to encapsulate other décor components like LED lights into your balustrade. Laminate glass with EVA interlayer is also water resistant.
With the above interlayer options for laminated glass, you are sure to find one that fits your budget and intended look. Glass balustrades have clean lines and a high reflectivity which lights up your interiors naturally. The extra natural light will also lower your daytime lighting costs. There is hence no reason to opt for any other material for your balustrade.
