What glass do I need for my frameless glass balustrade?
Installation scenarios are all different and there are a range of different glass options for you to choose from. Luckily the glass thickness are straight forward depending on the installation i.e. internal or external, residential or commercial. These are: 12mm, 15mm, 17.5mm, 19mm and 21.5mm. 25.5mm is also used for heavy commercial installations when a 3kN loading is needed.
The main element to remember is that what ever installation you have you need to form a ‘double barrier’ or ‘secondary barrier’. This means if you don’t want a handrail on you glass balustrade you need to go for a laminate glass. If you choose a mono glass you’ll need a handrail on the glass.
Installation scenarios all require different loadings and require different glass thicknesses depending on where they are. Here is a brief guide;
Stairs & landings in domestic installation (internal) = 12mm toughened or 17.5mm toughened laminate
Balconies in domestic installation (external) = 15mm toughened or 21.5mm toughened laminate
Light commercial (small offices) = 15mm toughened or 21.5mm toughened laminate
Restaurants & bars (places where higher volume of people) = 19mm toughened or 21.5mm toughened laminate (sentry glass)
