Knauf OmniFit glass mineral wool insulation roll 40 offers exceptional thermal and acoustic insulation. The versatile product can be used in various applications in both timber and steel frame construction applications. The multiple applications of the insulation rolls make it ideal for use across project types.

The non-combustible wool insulation is manufactured using Knauf’s unique bio-binder Ecose technology. The 1200mm wide insulation rolls are easy to cut and install, thus maximising on-site efficiency. They are sustainable products that do not contain any ozone-depleting substances or greenhouse gases. The open-cell nature of the fibreglass insulation effectively traps heated air, thus reducing heat loss. You get more insulation in one pack due to the compression packing technique used by Knauf.
