Materials used for walls and ceilings must adequately resist the spread of flame over the surface and if ignited, have a rate of heat release or rate of growth which is reasonable.
B3 Internal Fore Spread (Structure)
A Building must be constructed so that in the case of a fire its stability will be maintained for a reasonable period of time and party walls will adequately resist the spread of fire.
Concealed spaces and cavities will restrict unseen spread of fire and smoke by subdivision if necessary.
Fire Spread will be restricted by compartmentation.
