External Wall

In the case of external walls, the proximity of a building to the relevant (facing) boundary determines the probability of it being a danger to other buildings on adjoining sites (if it is on fire) or it being at risk from a neighbouring building on fire. Requirements made in connection with building regulations therefore specify different performances for external walls depending upon their distance from the relevant boundary.

For fire rated external walls for Class 7b and 8 buildings refer to the Stramit Uniguard System

Note: FRL */*/* (Fire Resistance Limit – *Structural Adequacy / *Integrity / *Insulation)

Following are some of the factors to take into account when determining correct specifications that ensure an external wall provides required fire performance.

  • Distance from relevant boundary
  • External cladding
  • Structural steel
  • Single storey buildings
  • Cavity barriers
  • Thermal insulation
  • Impact resistance
  • Wind loading
