Pitched roofs at rafter level


Glass Mineral Wool


Rafter Roll is a Glass Mineral Wool roll, designed for use in warm roofs where the roof is insulated at rafter level, that offers excellent thermal performance.

It is non-combustible insulation with the best possible Euroclass A1 reaction to fire classification, and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE® Technology.


  • Rolls are manufactured to allow cutting for installation at varying centre dimensions, providing maximum flexibility and on-site efficiency.
  • High levels of sound absorption and reduction characteristics reduce unwanted external noise such as traffic or drumming from rainfall on the roof.
