1 SCOPE
1.1 This Standard applies to mineral fibre thermal insulation manufactured in the form of faced and
unfaced batts, rolls and boards. 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.
1.3 This Standard also includes requirements for the manufacturer to provide the Job Site Certificate for
use by the applicators.
1.4 Recommended practice for verification of quality consistency by the manufacturer and by a third party
are included in Annex B for preformed insulation and Annex C for loose fill insulation.
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
