division wall

Fire division walls in a single storey E1 building between compartments of maximum size (14,000m2) are required to have two hours' fire resistance.

It is placed over the division wall between two wince pits so as to allow the cloth to descend into either compartment.

New city ordinances set standards for the thickness of walls and required "division walls" between buildings.

The compartment walls (in Scotland, division walls) and compartment floors are required to have a stipulated fire resistance depending on the size of the spaces as are all the other elements of structure as defined in the Regulations.

Despite numerous minor alterations since 1864 the largely intact features include the cell blocks, observation hall, turnkey's quarters, gaoler's quarters, kitchen wing exterior, warder's quarters, watch towers, perimeter and division walls, the iron entrance gates, entrance court, and yards with the exception of the 1861 female yards which were built over in 1925.
