Rockwool is moisture-resistant and breathable. This means that water vapour passes through it easily, reducing condensation. If the wool becomes damp or wet, it should be allowed to dry thoroughly and the original performance characteristics will be maintained.
Any bulk water that comes into contact with the insulation will not be absorbed by it but will drain away.
They offer excellent fire, thermal and acoustic performance and are easy to handle and install. RWA45 offers the highest level of fire resistance and as the slabs are water repellant, moisture build-up, dampness and rot are prevented.
Rockwool can be used across a number of general building applications, including for:
Acoustic insulation
Thermal insulation
Fire resistance
Rockwool is not the same as fiberglass insulation. While they have some similarities, Rockwool has a higher thermal resistance (R-Value), is more sustainable and has superior sound-deadening properties.
Rockwool is also slightly easier to handle and install as the slabs are firmer. It is water resistant where fiberglass is not and is much more fire resistant than fiberglass too.
