| Notice and Disclaimer: Technical Data Sheets for SBS and APP Polymer-modified bituminous membranes
Bituminous roofing membranes are governed by RGC Acceptance Criteria RGC ACWP-MOD (applicable to membranes accepted after July 1, 2023). The CSA Standard for these membranes, CSA A123.23 "Product specification for polymer modified
bitumen sheet, prefabricated and reinforced", forms the backbone of the RGC Acceptance Criteria and has replaced the older CGSB Standard CGSB 37-GP-56M, which was withdrawn in 2015.
The "British Columbia Building Code" (2024) references the CSA A123.23 Standard in both Part 5 and Part 9 of Division B. The Standard is also published in the National Building Code of Canada (2020), and the City of Vancouver Building Bylaw (2024).
Not all manufacturers of SBS and APP polymer-modified membranes publish technical data sheets that fully align with the CSA Standard. Therefore, the reader must verify this information independently of the RGC, to the reader's own satisfaction. Consult the local manufacturer's representative through the "Find a Member" page on the RCABC association website.
