Ambass-A-Door Ltd, a member of the British Woodworking Federation‘s Timber Window Accreditation Scheme, has supplied timber sliding sash windows for the recently opened extension at the Imperial War Museum in London.

Norwich-based Ambass-A-Door supplied 37 double-glazed timber windows from its Sandringham range, including 16 with arched tops, and a further four fully-reversible mock sashes that act as smoke vents in a stairwell for the four-storey Victorian building.
