Requirements for fire resistance - Switzerland

Requirements in Switzerland for fire compartment floors in housing, commercial and educational buildings are shown in the illustration on the right.

  1. detached single house
  2. building of low height (up to 11 m overall height)
  3. building of medium height (up to 30 m overall height), REI30 with extinguishing systems concept
  4. high-rise building with extinguishing systems concept (up to 100 m overall height)

Requirements for fire resistance - Germany

Germany (DE) settles the fire protection regulations in the state building regulations. Further specific regulations for highly fire resistant components used in multi-storey timber constructions are stated in their design guidelines (M-HFHHolzR). An application of timber and wood-based panel products in building class 5 is not provided for in planning law, but is often achieved through building object-specific fire protection concepts in implementation of means of compensation. The table shows building classes (GK) defined in Germany.

  • GK1 detached building, floor level of highest level (OKF) ≤ 7 m, building unit (NE) ≤ 400 m2
  • GK2 non-detached building, OKF ≤ 7 m, NE ≤ 400 m2
  • GK3 other buildings with OKF ≤ 7 m
  • GK4 OKF ≤ 13 m, NE ≤ 400 m2
