  • FALSE!

    There are certain locations that require a Group 1 as outlined in the 2019 NCC BCA but in most ‘specific’ or ‘other’ areas it is possible to have up to a Group 3 rating.

    The exact rating is dependent on the type of building; the section of the building; and if sprinklers are installed.

    Refer to the BCA Deemed-to-Satisfy Provision Specification C1.10 Table 3 or click here to use our free online Group Rating Calculator that instantly tells you what exact rating you will require.

  • FALSE!

    In most circumstances the substrate thickness of an acoustic panel will affect the fire rating of a multi-layered acoustic panel.

    It is important to review every detail in the fire certificate and ensure that it matches exactly what you want to specify. If there are ANY variations in the description of the fire certificate (including panel substrate , thickness, open area percentage and finish type.

  • FALSE!

    There are so many variations of acoustic panels available due to different substrates, finish and open area percentages (in fact Atkar has over 12,000 panel variations – you can view them here on our 3D Panel Visualiser!) that it is impossible to test them all.

    If there is no fire certificate available for your preferred panel variation, it is possible to work with your supplier and fire engineer and use certificates for similar products that have been tested to receive a Performance Solution.

  • FALSE!

    Standards Australia introduced ‘AS5637.1:2015 – Determination of fire hazard properties – Wall and ceiling linings’ to help determine accurate group numbers.

    Under the Standard, products which are multi-layered & perforated must be assessed to AS5637 and Group Numbers can only be obtained when assessed to AS5637.

    AS3837 (Cone Test) or AS9705 (Full Room Test) alone can no longer be used to issue a Group Number.

  • FALSE!

    Acoustic perforated panels consist of multiple layers of materials glued together with perforated holes or slots to achieve acoustic performance. Fire experts identified that multi-layered products with perforations can reduce the fire performance of a product.

    Prior to the 2016 NCC BCA, panels were often tested only as solid panel and were therefore achieving a Group 1 Rating this is why AS5637 was introduced – it is important to ensure your wall & ceiling lining panels have been tested to AS 5637.

  • FALSE!

    The term ‘FR’ has different meaning in different industries and companies.

    For Atkar Group, our substrate MDF FR refers to Fire Retardant, but some suppliers may imply their product is Fire Rated or Fire Resistant.

    It is important that you check Fire Test Certificates regardless of the claims that the supplier may say.
