Non-combustible Sarking

FIRESPAN non-combustible wall wrap and sarking is a heavy duty membrane which is BCA compliant and Deemed-to-Satisfy non-combustible for use in exterior cladding systems on all types of construction. Tested in accordance with AS 1530.1 and AS 1530.3 fire standards, FIRESPAN is available in waterproof and perforated variations. The reflective foil face on one side provides extra R-value when facing an air cavity and FIRESPAN is classified as a barrier to radiant heat, moisture ingress, draughts and dust penertration when installed as per AS 4200.2.

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.

Water Resistant

The heavy duty facing material structure of FIRESPAN sarking and wall wrap means there is no moisture ingress or break-down ensuring superior long term performance.

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.
