An insulating mineral wool with high thermal and acoustic performance
Slag wool is one of the mineral wools (rock wool, glass wool, cellulose wadding). It is made from the by-products of blast furnaces in the steel industry. Unlike rockwool, slag wool is iron-free, hence its grey colour. It does not have the same yellow appearance as rock wool, which is oxidised due to the presence of iron.
Slag wool is not carcinogenic. It includes a biosolubility certificate attesting to its in-body solubility should free fibres be inhaled, especially during use of the product.
Slag wool is mainly used in sprayed insulation, which is available in bulk format, as light flakes. It is rot-proof, non-combustible and easy to work with.
Slag wool provides your buildings with thermal performance, acoustic insulation and passive fire protection
Due to its structure, slag wool slows down the movement of air particles and dissipates sound energy. It improves the sound insulation of buildings by absorbing reverberated noise.
