Why specify it
Built for the way you build
Manufactured from volcanic rock
- KORE Stonewool is manufactured from natural volcanic rock, giving it a stable mineral structure that doesn’t burn, rot or lose its shape over the life of a building.
- Euroclass A1 reaction to fire classification, with no contribution to fire load.
Vapour-open by design
- Open-fibre, vapour-permeable structure that allows moisture vapour to pass through the wall build-up.
- Vapour-open (MU1) performance alongside high levels of thermal performance.
Two systems, one core
- KORE Stonewool ETICS Board 120 — high-density stone wool insulation board for rendered ETICS and EWI systems.
- KORE Stonewool Rainscreen 80 — high-density stone wool insulation board for ventilated façade and rainscreen systems.
A thickness for every U-value
- Available in thicknesses from 30–170mm to meet a range of project-specific U-value requirements.
- Please see the indicative U-value table below for further information.
Euroclass A1 fire performance
- Euroclass A1 reaction to fire classification.
- Vapour-open (MU1) performance, supporting a breathable wall build-up.
Built for most construction types
- Suitable for a range of construction types, including masonry, concrete and light gauge steel frame.
- Suitable for both new-build and refurbishment applications, subject to the relevant system specification.
