Struggling to find a supplier of OSB3 in WA for roof sheathing. I work for a building supplies and can’t find from any WA suppliers.
The only OSB supplier we know of in WA is Bunnings. Their website shows that they stock a range of OSB products, perhaps not in every store but if not immediately available they should be able to order it in for you. Bunnings supply to Trade customers as well as retail.
From wood solutions 37R , we are working on a project with fire protected timber. For penetrations, we can see 4.9.3 provides details related to penetrations and diagrams in Appendix A. Can you please provide some details if proposed method is from BCA or if these systems are tested systems by WoodSolutions?
The diagrams in Appendix A of our Technical Design Guide 37R are not tested systems, nor extracts from the BCA. They are test procedures to establish Resistance to the Incipient Spread of Fire (RISF), that is, they are to assist in setting up the tests. However, Section 5.14 of TDG 37R (page 102 onwards) provides assessed details from an Accredited Testing Laboratory that comply with the requirements of the BCA.
Tasmanian ‘oak’ is a marketing name that includes three similar timbers, alpine ash, mountain ash and messmate. All three fall into Group 3 as confirmed individually by our Regulatory Information Report 41117.11. A copy of RIR 41117.11 can be downloaded from our website via this link https://www.woodsolutions.com.au/resources/standards-codes/fire-test-reports.
