Glass Mineral Wool - Cavity Roll

Cavity Roll


Masonry Cavity Walls


Glass Mineral Wool


Cavity Rolls are designed for friction-fitting in timber and metal studs for drywall partitioning and may also be used in some external wall applications, dependent on the construction.

Cavity Rolls are ready cut into 2 x 600mm widths, to suit standard stud centres, allowing faster installation by removing the need to measure or cut on site. Installing a continuous piece of insulation within the studs avoids butt joints and potential acoustic bridging associated with batts.


  • Rolls are ready-cut into 600mm widths for fast installation
  • Friction-fitting between studs for ease of installation
  • Suitable for use in metal or timber studs
  • Provide excellent acoustic performance and helps prevent acoustic bridging
  • Advanced compression technology provides more per pack for less storage, handling and transportation
  • Non-combustible A1 Euroclass Reaction to Fire classification
  • Manufactured with ECOSE® Technology for improved handling and installation
