170mm Knauf Insulation Loft Roll (8.01m2)
Knauf Loft Roll 44 Combi-Cut
Flexible, High-Performance Glass Mineral Wool Insulation for Loft Spaces
Knauf Loft Roll 44 Combi-Cut is a lightweight, non-combustible glass mineral wool insulation designed specifically for use in cold loft applications. Manufactured using Knauf's advanced fibre technology, it provides excellent thermal performance while helping to reduce heat loss through roof spaces, improving energy efficiency and lowering heating costs.
Supplied in a convenient Combi-Cut format, the rolls can be easily split into narrower widths to suit different joist spacings, making installation quicker and reducing waste on site. The flexible nature of the insulation allows it to fit snugly between and over ceiling joists, creating an effective thermal barrier and helping buildings meet current building regulation requirements.
Ideal for both new-build and refurbishment projects, Knauf Loft Roll 44 is odourless, easy to handle, and manufactured from a high proportion of recycled materials, making it a sustainable choice for residential and commercial developments.
