We had a fire on an external wall, where the studwork caught light due to a storage heater air gap collapsing. I'm just about to do the repairs. The wall from outside in is brick, air gap, felt, ply, studwork and plasterboard. Where as I am 99% sure the fire was caused by the airgap collapsing betwen the storage heater and the plaster board, is there any suggestions to 'maximise' my comfort zone of not having a repeat. Thanks
