Application

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.


Rafter Roll 32 is designed for insulating between the rafters of pitched roofs in new and existing buildings. It is easy to cut and friction fit, and can be used either as a single or double layer between rafters, or as the first layer of a two layer system in combination with a thermal laminate board.

Description

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.


Features and benefits:

  • Good thermal performance.
  • Non-combustible A1 Euroclass Reaction to Fire classification.
  • Good sound absorption characteristics.
  • Friction fitting between rafters.
  • 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.
  • A+ generic BRE Green Guide rating.


Certification:

  • Eurofins Gold.
  • Euroclass A1 Reaction to Fire Classification.
  • Green Guide Rating A+.
  • CE Marking.
  • Red List Free.
  • Declare.
  • UKCA.
  • EN 15804.
  • EUCEB.
  • Made in Britain.


Durability:

Rafter Roll 32 is odourless, rot proof, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria.


Standards and certification:

Rafter Roll 32 is manufactured in accordance with BS EN 13162, ISO 50001 Energy Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management systems, as certified by TÜV Nord. All our Glass Mineral Wool products have been awarded the DECLARE ‘Red List Free’ label. Having the ‘Red List Free’ label means that there are no ingredients in the product that are on the red list - including formaldehyde or phenol.


Real performance:

Glass and Rock Mineral Wool are easier to install correctly than other insulants such as rigid boards because they adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps. Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application. Environmental Rafter Roll 32 contains no ozone-depleting substances or greenhouse gases.
