Approved document B, Fire Safety, Volume 1 Dwelling houses, suggests that for the purpose of the performance of wall linings, a wall includes:

  • The surface of glazing (except glazing in doors).
  • Any part of a ceiling which slopes at an angle of more than 70º to the horizontal.

But a wall does not include:

  • Doors and door frames.
  • Window frames and frames in which glazing is fitted.
  • Architraves, cover moulds, picture rails, skirtings and similar narrow members.
  • Fireplace surrounds, mantle shelves and fitted furniture.

However, Approved document C, Site preparation and resistance to contaminants and moisture, suggests that a wall is:

Any opaque part of the external envelope of a building that is at an angle of 70° or more to the horizontal.

[edit] Cavity wall

A wall constructed from two skins of masonry, the outer skin of which can be brickwork or blockwork and the inner skin of which is generally of blockwork, separated by a cavity to prevent the penetration of moisture and to allow for the installation of thermal insulation.
