Fire Protection of External Walls
In the case of external walls, the proximity of a building to the relevant (facing) boundary determines the probability of it being a danger to other buildings on adjoining sites (if it is on fire) or it being at risk from a neighbouring building on fire. Requirements made in connection with building regulations therefore specify different performances for external walls depending upon their distance from the relevant boundary.
A further consideration for external walls is their ability to weatherproof a building. The unique Siniat WEATHER DEFENCE is concert with PROMATECT boards can provide both weather and fire resistance in the same system.
For fire rated external walls for Class 7b and 8 buildings refer to the Stramit Uniguard System http://www.stramit.com.au/product-range/stramit-uniguard
