CAN/ULC-S702-97

1. SCOPe 1.1 This standard applies to mineral fibre thermal insulation manufactured in the form of faced and unfaced batts, rolls, boards and sheets. Where facings are used, they shall be either permeable or vapour retarding membranes, as defined in Table 1 for Types 2 and 3, respectively. This standard does not permit the application of kraft paper facings on batts and rolls. It also applies to loose fill mineral fibre thermal insulation when used in unconfined spaces with slopes not exceeding 4.5:12. 1.2 This standard specifies performance requirements and test methods for the products used under normal climatic conditions to thermally insulate attics, floors, ceilings and walls (above and below ground grade) in light frame construction buildings and manufactured housing. This standard does not apply to mineral fibre board for above roof decks which is covered by CAN/CGSB-51.31. 1.3 This standard also includes a requirement for Certification of Coverage by the applicators of loose fill insulation in attics and a method for verifying this application (Appendix A). Limits for any deviation of applied mass per unit area and of thickness from the design values stated on the application chart are also included in Appendix A. 1.4 Recommended practice for verification of quality consistency by the manufacturer and by a third party are included in Appendix B for preformed insulation and Appendix C for blowing wool. Furthermore, optional requirements and test methods on corrosiveness and fungi resistance are provided in Appendix D. 1.5 The testing and evaluation of a product against this Standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the health and safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish health and safety practices, in conjunction with any existing applicable regulatory requirements, prior to its use.
