Fire Resisting Materials

Fire-resisting materials are required by the London Building Acts; see a very full list of them in Sched. I. of the London Building Act, 1930 (20 & 21 Geo. 5, c. clviii.), Chitty's Statutes. They include, for general purposes, 'brickwork constructed of good bricks well burnt,' etc, and 'solidly put together with good mortar,' etc., and for the special purposes of 'verandahs, balustrades outside landings, the trades, strings and risers of outside stairs, outside steps, porticos and porches, oak, teak, jarrah, karri or other hard timber not less than 1' inches finished thickness.'
