The fire insulation comes in the form of rock wool insulation or different types of cladding boards, such as plaster or calcium silicate. Täby BrandskyddsTeknik performs fire insulation of load-bearing structures that are at risk of collapsing in the event of a fire.

Fire-rated insulation and dimensioning of fire protection materials

Fire technical dimensioning of fire protection material depends on the same parameters as when dimensioning fire protection paint. That is, type of building, static utilization and F / A.

Fire protection of surface layers is divided according to the following classifications:

  • Europe Standard B-s1,
  • dO (former surface layer class 1),
  • anti-ignition clothing.

The fact that the fire protection of surface layers within a fire cell is optimized is crucial for the development of smoke and the spread of fire during the initial stage of the fire to be limited.
