Knauf Frametherm Roll 40 - 140mm

ECOSE® Technology is Knauf Insulation's unique binder system for mineral wool products. It uses a bio-based binder derived from plant-based materials, reducing the environmental footprint by eliminating formaldehyde and reducing energy usage during manufacturing.

Yes, glass mineral wool offers excellent sound absorption properties, significantly reducing noise transmission between rooms and from external sources.

This specific product, Frametherm Roll 40, is optimized for timber and steel frame construction. For masonry walls, different insulation solutions may be more appropriate.

Always wear personal protective equipment (PPE), including gloves, eye protection, and a dust mask, when handling and cutting mineral wool insulation to prevent irritation.

The product has a thermal conductivity (lambda value) of 0.040 W/mK. The R-value and U-value will depend on the overall construction assembly, including the thickness of the insulation and other building materials.

The product is supplied in rolls, typically compressed for transport. It covers 9.14m² per roll with a thickness of 140mm.

The rolls are pre-cut into 2x570mm sections, which are designed to suit commonly used timber stud spacing in the UK. The 140mm thickness is suitable for deeper cavities often found in modern framing.

Wear appropriate PPE (gloves, long sleeves, eye protection, mask) during installation. If irritation occurs, wash the affected area with soap and water.

Ensure the insulation is cut to size accurately. Gently push the insulation into the cavity, ensuring it fills the space without being overly compressed. Check that studs are plumb and square.

Verify the cavity depth and compare it to the insulation's 140mm thickness. If the cavity is smaller, you may need to compress the insulation slightly or use a thinner product. If larger, consider adding a second layer or a thicker insulation product.
