Durability

Rocksilk® Soffit Linerboards are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

Standards and certification

The rock mineral wool element of Rocksilk® Soffit Linerboards is manufactured in accordance with BS EN 13162, ISO 50001 Energy Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management Systems, as certified by TÜV Nord.


Real performance

Glass and rock mineral wool are easier to install correctly than other insulants such as rigid boards because they adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps. Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application.


Environmental

Rocksilk® Soffit Linerboards contains no ozone-depleting substances or greenhouse gases. For further environmental information consult the relevant Environmental Product Declaration, available on the Knauf website.


Handling and storage

Rocksilk® Soffit Linerboards are easy to handle and install, being lightweight and easily cut to size, where necessary. Rocksilk® Soffit Linerboards are supplied in recyclable polythene packs (4 LDPE) or loose on a hood wrapped pallet which are designed for short term protection only. For longer term protection on site, the product should either be stored indoors, or under cover and off the ground. Rocksilk® Soffit Linerboards should not be left permanently exposed to the elements.
