§ Mrs. Ewingasked the Minister of Housing and Local Government if he will make a statement on the use of pitch fibre pipes in the construction of tall flats.
§ Mr. Freeson:The building regulations in England and Wales are not contravened by the use of pitch fibre pipes for soil stacks in tall buildings; tests have shown that such pipes are not a fire hazard provided they are properly encased in fire-resisting material.
