Knauf Universal Slab RS60

Earthwool KNAUF RS60 is rock mineral wool slabs which are unfaced and available in varied range of densities from 33 to 200 kg/m3. These slabs can be applied in any sort of building whether commercial or domestic as it features excellent acoustic and thermal properties.

The 7.00 MN.s/g.m of vapor resistance makes it more appropriate for insulation purposes. It is light-in-weight and easy to handle as well as install that can be cut to a desired size as per your requirement.
