Want to add glass balustrades to a project over 11 metres?

If you have a construction project for a residential building with one or more dwelling that is over 11 metres in height, you must comply with all fire safety regulations set out in the construction industry’s Approved Document B.

Approved Document B addresses fire safety precautions and lays out building regulations which were updated in 2022. The regulations refer to the ban on combustible materials used on external surfaces of buildings over 11 metres.

Glass balustrading is now a dominant feature of the exterior of tall residential buildings, giving residents access to the outdoors and maximising the amount of daylight that is brought into the internal space. In line with Approved Document B, all glass balustrading must comply with the specified fire regulations.

OnLevel’s Flameless fire rated glass balustrades comply with Approved Document B, providing the ideal glass balustrading solution for projects over 11 metres in height.

Which Approved Document B fire safety standards must glass balustrading comply to?

The fire safety standards of Approved Document B that concern glass balustrading include:

  • means of escape
  • the internal isolation of a blaze to prevent it from spreading
  • external fire spread
  • access to the building for firefighters
  • the internal spread of a fire due to the structure of a building or materials used in its lining.
