Abstract

Overview

ISO 8144-2:1995 specifies requirements for bonded mineral wool thermal insulating mats (batts and rolls) intended for horizontal applications in ventilated roof spaces with unrestricted ventilation. The standard defines product properties, acceptance tolerances, testing and marking information. These mats are not designed to support imposed loads and are intended to preserve the ventilation path in roof construction.

Key topics and requirements

Scope and intended use
- Applies only to mineral wool mats for horizontal roof applications where any excess thickness will not restrict the ventilated air space.
- Mats are not load-bearing; only mechanical properties needed for handling are specified.
Dimensional tolerances
- Width: +2% or +10 mm, whichever is less (measured on averages).
- Thickness: average tolerance −5% / +25%; individual measurement points must not deviate more than 15 mm from specimen mean.
- Squareness: for every 100 mm along the shortest face, max deviation 1 mm.
- Length: negative tolerance −2% with specified allowances on average measured values.
Thermal resistance (R-value)
- Manufacturer declares R-value and mean test temperature.
- Measured R must be at least 95% of the declared value.
- Test methods: ISO 8301 (heat flow meter) or ISO 8302 (guarded hot plate). In dispute, ISO 8302 is authoritative.
- Test conditions: mean test temperature typically 23 °C or 10 °C (40 °C may be agreed in tropical regions); temperature difference ≥ 20 °C.
Specimen preparation and conditioning
- Specimens oven-dried or conditioned at 23 °C ±2 °C and RH
