FIRESPAN is a range of pliable building membranes which are all Deemed-to-Satisfy non-combustible for use in exterior cladding systems in all types of construction. Tested in accordance with relevant Australian fire standards, FIRESPAN is availalbe in three variations to suit different appliactions and climate zones; a vapour barrier (FSS), a perforated membrane (FSB) and a vapour permeable membrane (FSM). All variations have been tested as per AS 4200.1 and when installed as per AS 4200.2, they provide a Deemed-to-Satisfy weatherproofing barrier in accordance with NCC 2022, Clause F3D3.

NCC 2022 Non-combustible

FIRESPAN membranes are all Deemed-to-Satisfy non-combustible in accordance with either NCC 2022 Clause C2D10(6)(f) and/or (g) meaning they can be used on any building of types A, B and C construction.

NATA Fire Testing

FIRESPAN membranes have been appropriately tested to relevant Australian standards including AS 1530.1, AS 1530.2 and AS 1530.3 by NATA accredited laboratories and are all Deemed-to-Satisfy non-combustible.

Easy to Use

FIRESPAN pliable membranes are all high strength and ultra flexible products easily adaptable for wrap-around areas and varied surface types therefore making them quick, cost-effective and easy to install.

Anti-tear Strength

With ultra heavy duty multi-layer construction, FIRESPAN pliable membranes are all able to withstand moderate wind and won’t tear of the building when under pressure in normal conditions.

High Durability

All variations of FIRESPAN membranes use multiple layers of either high-strength fibre-glass, pure aluminium foil or specialist textiles each offering excellent durability and resistance to delamination over time.

NCC 2022 Compliant

FIRESPAN pliable membranes have all been tested in accordance with relevant Australian fire standards in accordance with AS 4200.1 giving confidence to builders and contractors for suitability on all projects.

All Applications Covered

Available as a vapour barrier, perforated membrane or vapour permeable membrane, FIRESPAN is suitable for use in all different applications and climate zones as per the latest NCC requirements.

Protects the Building

During construction FIRESPAN pliable membranes will help protect the building structure and insulation from the external elements helping to prevent the onset of any degredation or corrosion.
