Kanuf Earthwool Loft Roll 44 Insulation Combi Cut

Knauf Earthwool Loft Roll 44 Insulation is a glass mineral wool product engineered for thermal performance in pitched roofs and ceiling areas. Manufactured with ECOSE® Technology, it offers low dust levels, a natural pale brown colour, and a softer fibre texture for easier handling. The roll is supplied in a combi-cut format, allowing installers to use it either as full-width insulation or to split it into pre-cut sections for joist spacing.

Its dense fibre structure provides reliable thermal insulation to support compliance with Approved Document L requirements in residential properties. The mineral wool composition is vapour-permeable and dimensionally stable, helping maintain consistent performance throughout the building’s service life. The insulation is non-combustible to Euroclass A1, offering enhanced fire protection in loft and roof constructions.

Earthwool Loft Roll 44 is lightweight, easy to position between ceiling joists, and suitable for cold roof applications where energy efficiency and heat retention are essential.

Installation Guide:

• Ensure loft or ceiling area is clear of debris and safe to access
• Position the roll between joists using combi-cut sections where required
• Lay additional layers across joists to achieve full coverage
• Cut cleanly with a sharp insulation knife for accurate fitting
• Avoid compressing the insulation to maintain declared thermal performance
• Ensure ventilation pathways remain unobstructed in cold roof systems
