Material and uses
Insulation for every project.
Basalt wool is a mineral wool made by melting rocks such as basalt, diabase and dolomite at 1400–1500 °C and spinning them into fibres. The fibrous structure insulates against heat and absorbs sound, while its mineral nature contributes to fire protection.
97%natural fibres
3–5 µmfibre diameter
40–200kg/m³ density
It is produced as boards, mats, pipe sections and loose wool; the form, density and performance are chosen according to use.
Sound absorption
The fibres absorb sound waves and reduce reverberation and noise transmission between spaces.
Fire protection

Practical information
Handling and storage.
Keeping the packaging intact and protecting the product helps maintain the insulation's properties. Wear protective clothing and equipment for skin, eyes and airways when handling.
For a quote: state the product, variant, thickness, dimensions, quantity and place of use.
Covered storage
Indoors; outdoors, cover the packs completely with a tarpaulin.
Weather protection
Protect the packs from water, moisture and sunlight.
Stored on pallets
No direct contact with the ground; do not stack pallets during storage or transport.
Protected transport
Cover the load with a tarpaulin and do not place materials on top that could damage the packaging.
Which basalt wool is used for ventilated facades?
Gold and Gold Plus (50–90 kg/m³, λ 0.035 W/mK) are used for ventilated facades and curtain walls. The Premium F range is designed for rendered ETICS systems.
Which wool goes on a flat roof?
Premium R, with high density and a compressive strength of at least 35 kPa (up to 50 kPa for Premium R 150), for industrial roofs, terraces and pitched roofs.
Is basalt wool fire resistant?
The mineral nature of the material contributes to fire protection; the series indicated in the catalogue have reaction to fire class A1. For doors, the A1 class of the material does not automatically mean the complete door is fire-rated.
What information is needed for a basalt wool quote?
