Self-supporting Membrane Ceilings
These are normally non loadbearing and, depending on the type of construction, are used to provide protection from fire attack from below and/or above. Ceiling panels are fixed into a steel or timber framing system spanning and supported between two walls.
Self-supporting membrane ceilings should normally be tested or assessed in accordance with BS 476: Part 22: 1987 to satisfy the failure criteria of integrity and insulation.
