65. Boilerhouse roof.
A view northwards, down river, with the moribund Aylesford works of the West Kent Portland Cement Co immediately on the other side of the river, by the creek remnants of the river bends which defined the later island site. Further away is the works of the Burham Brick Lime and Cement Co, originally set up by Thomas Cubitt.
The boiler house roof is typically of fireproof construction, being corrugated iron sheeting directly on the steel framework, contrasting to the slates on wooden sheathing used for the beaterhouse and machine house.
