Earthwool Insulation is a popular brand - it is rot-proof, odourless, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria. The fact that Earthwool has practically no smell is a huge plus for the many insulation installers who are used to transporting glasswool insulation around in an open van. It is chemically neutral, does not contain impurities and comes with a 50 year warranty. In practice, this means that whether Earthwool is installed at the time of building the home, or in a retrofit application (i.e. installing insulation in the ceiling of an older building), providing it is correctly installed, you can expect the insulation to last as long as your home.
Knauf Earthwool batts in particular has gained increasing popularity with both professional installer and D.I.Y. renovators due to its more comfortable handling. The exceptional compression packaging means more coverage per bag, which in turn results in reduced handling, transport and storage costs.
Knauf Earthwool - Naturally Brown
Earthwool Insulation is made using ECOSE® Technology and benefits from a formaldehyde–free binder made from bio-based materials instead of petroleum-based chemicals. The technology enhances the product's environmental credentials without affecting its thermal, acoustic or fire performance. Knauf Earthwool is naturally brown and contains no dye or artificial colouring.
Earthwool insulation is made from renewable products such as recycled glass bottles and sand. It is less dusty, and many installers claim it's easier to cut and install than traditional types of glasswool insulation. When installing Knauf insulation in your ceiling, keep in mind that once open, the insulation will expand to several times its size. It's best not to open more than one bag at the time, as this makes it easier and safer to move around in the tight ceiling space.
