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.
