Insulation is about more than a number on a technical datasheet. It helps create a comfortable indoor environment through thermal resistance, sound absorption and appropriate fire performance.
Knauf Earthwool is glass mineral wool insulation manufactured using ECOSE® Technology. It combines thermal and acoustic properties with a softer handling experience and its distinctive natural brown appearance.
Whether you're improving an existing home or insulating a new ceiling, Earthwool offers a range of products designed for suitable residential building applications.
Explore the Earthwool RangeECOSE® Technology is Knauf Insulation's innovative binder technology, made using rapidly renewable materials instead of conventional formaldehyde-based binders. It contains no added formaldehyde and is designed for low product emissions and improved handling comfort.
Knauf Earthwool helps slow heat transfer through properly insulated ceiling areas. It can help reduce unwanted heat gain during summer and heat loss during winter, supporting more comfortable indoor temperatures.
The fibrous structure of glass mineral wool absorbs sound energy. This makes Earthwool useful in suitable acoustic constructions, although actual noise reduction depends on the complete ceiling or building assembly.
Knauf Ceiling Roll has a Euroclass A1 reaction-to-fire classification, meaning the specified insulation material is non-combustible. This is a material classification, not a fire-resistance rating for an entire roof assembly.

This can help limit unwanted heat gain during hot weather and reduce heat loss during colder conditions. Actual performance depends on the insulation thickness and the complete roof construction.
Glass mineral wool has sound-absorbing properties. Earthwool can contribute to improved acoustic performance when used in an appropriately designed ceiling or building assembly.
The amount of sound reduction depends on the complete construction, including ceiling boards, gaps, penetrations and installation details.
Knauf Ceiling Roll has a Euroclass A1 reaction-to-fire classification, identifying the specified insulation material as non-combustible.
This is a classification of the insulation material, not a fire-resistance rating for an entire roof or ceiling construction.
