Glass Mineral Wool - Ultracoustic-A Roll (Combi-cut)

Ultracoustic-A Roll (Combi-cut)


Internal Walls / Partitions, Internal Floors


Glass Mineral Wool


Ultracoustic-A Rolls (Combi-cut) offer superior acoustic performance for internal partition walls, suspended ceilings, intermediate floors and some external wall applications.

Suitable for both acoustic and thermal applications, they are ideal for use in areas where heightened privacy or sound insulation is of importance, e.g. cinemas, boardrooms, or consultation chambers. Rolls are pre-cut into 2 x 600mm widths, removing the need for measuring and cutting on site for convenience and speed of installation. Installing rolls in partitions removes joints associated with slab installations, reducing the likelihood of acoustic bridging.


  • Superior sound absorption characteristics improve the acoustic performance
  • Friction fitting between studs
  • Ready-cut rolls to suit 600mm stud centres for convenience, faster installation and no butt joints
  • Suitable for use in metal or timber studs
  • Non-combustible A1 Euroclass Reaction to Fire classification
