A2 -Class fire rated membranes: TECHNOLOGY IS READY!

Facade Fire - Dubai

After the fires in Grenfell Tower at London, UK in 2017 that unfortunately killed over 72 people and injured dozens of others, at Baku Azerbaijan (17 losses), at Dijon France (7 losses), at Shanghai China (53 losses), several fires at Dubai and Australian without losses and many other similar fire episodes, the local authorities decided to act seriously. In the last year regulations were amended, materials were prohibited and plenty of buildings are undergoing re-cladding works.

Usually high rise buildings require a full-scale mock up tests (as BS8414, NFPA285, ISO13785, etc.) and material combustibility tests (as EN13501, ASTM E84, etc.) to confirm the fire performance of part of façade or if the material is in compliance with legislation. However this tests in most situations are not clear and not arise the in-use real application. In the end, the above tests fail on the evaluation of a fire real scenario as a whole picture and geometry, fuel load, façade perforations, cavities, external factors as wind and many others are not properly considered.     

Therefore, it is imperious that the construction industry develops, as much as possible, solutions with special fire behavior to help designers, specifiers and insurers to have enough confidence to ensure the level of building fire safety that protects the building property, as well as, human lives.

Aligned with the above, Effisus has develop and is introducing in the European market, the EFFISUS Breather FR membrane –  The one and only A2 Class fire rated solution!

Presents a fire resistance, class A2-s1, d0 according to the European Standard EN13501-1:2007+A1:2009. It is a membrane with fiberglass basis (95%), which among other characteristics as high tensile strength, a dimensional stability that does not vary with atmospheric conditions, a high resistance to heat ≈ 1500 °C, excellent chemical resistance and high durability.

Effisus FR, besides its excellent fire resistance, is UV-resistant, windtight and watertight.

    Kindly share the detail drawing and price list

  • Paul Williams says:

    Under the new UK regs we need to use fire rated cavity trays in certain types of wall build up. Is there anyway of forming cavity trays using this material?

      Thank you for your comment! Your message will be answered by our Key Account Manager, via email. Thank you.

  • Dominik says:

    What type of certification and approval certificates could you provide to support this product in the UK market (i.e. BBA, Fire test reports, etc.)

  • kane says:

    Hi,

    Please can you send me the BBA certificate confirming the A2-s1,d0 compliance?

    kind regards,

    kane

  • Kevin Hall says:

    Could you kindly please send me a copy of the price lists and the relevant certification for your Effisus FR A2 rated membrane?

  • Hello
    Can you provide all certifications and technical data sheets for your product. Also can you confirm its availability on the UK market as well as contact details for your UK representative/agent. Thank you ever so much.

      Thank you for your comment! Your message will be answered by our Technical Office Manager, Miguel Silva, via email. Thank you.

  • Martin Fox says:

    Can you provide any technical data sheets for Effisus FR.
    Is this product suitable and accredited for use as a cavity tray? Are any BBA certificates available?

    • Effisus Effisus says:

      Dear Martin Fox,
      Thanks for your question. We will send the datasheet directly to your email address.
      We are working closely with Labs and our R&D Dep to evaluate the possibility of application of Effisus FR as a cavity tray.
      We are also proceeding with BBA for our full façade envelope system – final certification will be available later this year.

  • Lee Ramage says:

    Please forward details of the planned certification. We consistently come across this issue and are keen to mitigate the project costs of adopting a stainless steel system.
    Keen to understand more about your product, applications and plans for testing/certification of same as a cavity tray.

    We are also often asked for classified materials to use as DPC and perpend weepholes. Any potential for adopting your product, and an understanding of costs & spec would be appreciateed

    • Effisus Effisus says:

      Many thanks for your enquiry. We have an R&D open project in regard to cavity tray. Our solution will not be based on stainless steel system as we know it is not cost-effective, we are currently studying the product possibilities in accordance with the project technical requirements, test standards and fire performance. For a fully tested solution, it will still take some time but we will communicate at that time.

  • ryan says:

    Hi, please can you send me the data and application usage for this product as a cavity tray. Pricing and availability too if possible

    • Effisus Effisus says:

      Hi Ryan, regarding cavity tray, we are in the concept design phase working closely with the Labs and our R&D Dep. We are currently studying the product possibilities in accordance with the project technical requirements, test standards and fire performance. Consequently, we will proceed with the testing and product certification BBA, but we still need some time for a fully tested solution. Let us know if I can be of any further assistance.
