ISO 8144-1:2026

This document specifies the properties and acceptable tolerances for bonded man-made mineral wool thermal insulating mats (batts and rolls). The mats specified in this document are for use within ventilated spaces of buildings where the essential ventilation of the space can be restricted if the thickness recovery of the insulation is excessive. See ISO 9774:2004, Figure 1, for typical locations. They can be supplied flat, folded, or in the form of a roll. This document specifies the properties to be declared by the manufacturer at the time of delivery, as well as some test methods for the determination of these properties. This document provides limiting values for most of the properties. These limiting values are for specification purposes only. Mats can be supplied with a factory-applied facing, but facings are not covered by this document. Because mats are not generally designed to support any applied load, only the mechanical properties required for adequate handling during application are specified.
