Not all SBS and APP polymer-modified membranes accepted by the RGC prior to July 1, 2023 publish technical data sheets that align with the newer CSA Standard. While the RGC provides technical sheets for viewing in the Roofing Practices Manual, not all may be current or even conforming to the standards they purport to align with. Therefore, the reader must validate this information independently of the RGC, to the reader's own satisfaction.
