The Knauf Insulation OmniFit Roll 40 is a glass mineral wool roll designed for multi-purpose
This product is applied via friction fitting between studwork, ensuring a tight seal that prevents air movement and minimises heat loss through gaps. It provides a thermal conductivity of 0.040W/mK and an R-Value of 3.75m2K/W, alongside acoustic absorption properties that exceed Part E of the Building Regulations.
Produced using Knauf’s bio-based ECOSE Technology binder, this roll achieves a Euroclass A1 reaction to fire classification. It is supplied compression-packed to reduce storage requirements and the coverage per roll is 5.46m2.
- Glass mineral wool core provides a thermal conductivity of 0.040W/mK.
- Euroclass A1 fire rating ensures non-combustible fire resistance.
- Partially perforated rolls allow combi-cutting for 400mm or 600mm centres.
- Friction fitting prevents edge gaps to minimise unwanted heat loss.
- Delivers acoustic performance exceeding Part E of Building Regulations.
