Demountable Barriers

Durasteel demountable panel fire barrier systems are primarily installed in areas that require high levels of fire and blast protection, whilst still allowing access for maintenance and replacement of large equipment, such as transformers.

In addition to the standard features of a Durasteel barrier, including 4 hour fire rating in both directions and up to 56dB acoustic rating, our demountable barriers can be quickly and easily removed, either as prefabricated modules or piece-by-piece.

Removing a demountable barrier leaves a completely unobstructed and flush-finish opening, through which equipment can be freely transported. This removal process can be completed entirely by hand, and does not require the use of any specialist lifting equipment.

For areas such as metro tunnels that are subject to extreme changes in air pressures or frequent vibration, the barriers can be additionally engineered to resist these pressures and cyclic loading.

Services that are required to pass laterally through the barrier can be separately framed out in a non-demountable section and fire-stopped using our certified penetration seals. If regular personnel access into the room is required, a Durasteel door can also be built into the demountable barrier.
