What are the fire regulations for soffit insulation in Scotland?

The mandatory standard states that:

“Every building must be designed and constructed in such a way that in the event of an outbreak of fire within the building, the development of fire and smoke from the surfaces of walls and ceilings within the area of origin is inhibited.”

The Technical Handbooks provide guidance on achieving the standards set in the Building Regulations.

Note that following the guidance in full should be accepted as compliance with the Regulations. However, there may also be other ways to comply with the requirements than those described. The project Principal Designer (during design stages), Principal Contractor (during construction) and relevant consultants (such as Fire Engineers) should be consulted to ensure compliance with the Building Regulations.

Domestic buildings

The Building Standards Technical Handbook for domestic buildings says the following:

  • A protected zone should have ceiling surfaces which achieve Euroclass A1, A2 or B.
  • A room, unprotected zone or protected enclosure should have ceiling surfaces with a Euroclass no worse than C.

Note that a protected zone is defined as part of an escape route which is within a building, but not within a room, and to which access is only by way of a protected door and from which there is an exit directly to a place of safety.

Non-domestic buildings

The Building Standards Technical Handbook for non-domestic buildings states that every room, fire-fighting shaft, protected zone or unprotected zone, should at least meet the guidance in the table below.
