Standard for Mineral Fibre Thermal Insulation for Buildings 

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.

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 also includes requirements for the manufacturer to provide the Job Site Certificate for use by the applicators.

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.
