confidence in quality

We care about your safety and our environment. That’s why our Muros Wall Panels are certified to meet and exceed NZ, AU and US fire safety standards in addition to being ISO14001 Environment and ISO9001 Quality accredited.


Muros Wall Panels have been tested to latest Australasian fire rating standards: ISO 5660 (NZ) and AS/NZS 3837 (Australia).
Muros Wall Panels have a Group 3 Number Classification rating as tested and reported by BRANZ (click link to view, print or download BRANZ certificate copy).
Installed correctly, Muros Wall Panels should not to be subjected to direct, strong or constant heat. Panels are fire resistant, however to maintain a quality appearance heat should not be directed onto the panels and an appropriate fire-retardant substrate is to be used.

Muros carries in stock wall panels with a Group 3 Number Classification. Muros Wall Panels with a Group 1 Number Classification (virtually inflammable) are also available and are made to order (please discuss with Muros during the projectplanning stage).
View here the New Zealand Building Code table for wall and ceiling surface finishes. The table details the co-relation of Australian or European classifications to the Group Number requirements.
