The above diagram is in reference to ‘BS 6262’ (Critical locations) that determines where safety glass needs to be installed.
These locations are 800mm from floor level, 300mm from any door that is also 1500mm from floor level.
Any units in this area (in the green section) must comply to ‘BS EN 12150 or BS EN 14449’.
These are units 2, 3, 5, 6, 7, 9, 10, 11 and 12.
Safety glass is categorized as A, B or C, with A being the highest grade. Please see below for details.
|Toughened BS EN 12150||A||Toughened or tempered glass has been heat treated to cause the inside and surface forces to act on each other strengthening the glass. When broken, pressure is released turning the glass into small particles.|
|Laminated BS EN 14449||A, B & C||Laminated glass consists of two sheets of ordinary float glass adhered together by a plastic interlayer. When broken, any shards will remain attached to the plastic interlayer reducing the risk of injury.|
|Wired||C||Wired glass is a form of laminated that also has a wire mesh embedded in to it. This glass can also give a level of fire resistance over normal laminated glasses.|
