Wall isolation system
Combine the composite board with a separated stud frame, acoustic infill and resilient connections to reduce direct airborne transmission and structural bridging.

Dense mineral fiber
Build quieter, safer and better-insulated spaces.
Its open fibrous structure dissipates sound energy inside cavities while the dense, stable board adds thermal resistance and supports fire-safe construction. For sound isolation, rock wool should be combined with framing, mass layers, separated construction and carefully sealed joints.

System approach
Performance comes from the complete assembly.
Rock wool absorbs energy within the cavity; the surrounding construction blocks transmission. Select every layer together for the required project result.
- 01Framing or substrateCreates the cavity and provides secure support for the board.
- 02Rock wool infillFits closely between members without gaps or compression.
- 03Mass facing or claddingGypsum board, cement board or facade layers provide the sound-blocking surface.
- 04Sealed perimeterJoints, penetrations and interfaces are detailed to limit acoustic leakage.
System design
Build the board into a complete isolation assembly
Final acoustic performance depends on framing, cavity infill, resilient connections, perimeter sealing and the number of lining layers.
Floating floor system
Use above a resilient underlayer within layered floor constructions to control impact noise and improve separation between occupied floors.
Suspended ceiling system
Integrate with resilient hangers, a metal ceiling frame and absorptive infill for cinemas, KTV rooms and other noise-sensitive interiors.
Performance range
Class A fire performance across five density choices.
Choose density and thickness around the required rigidity, loading, cavity depth and tested wall, ceiling or envelope system.
Density selection
Five grades for different structures.
Higher density can add rigidity and fiber mass, but the correct grade depends on the tested assembly and fixing method—not density alone.
Lightweight cavity infill
For broad wall and ceiling areas where easy handling and reliable cavity coverage matter.
Balanced acoustic grade
A practical balance of board rigidity, absorption and installation weight.
Robust partition grade
Added fiber mass for demanding partitions, ceilings and equipment-room linings.
High-density construction
Firm boards for facade, industrial and mechanically retained build-ups.
Specialist heavy grade
Maximum density in the range for selected high-load acoustic and thermal assemblies.
Thickness options
Choose 50 mm or 100 mm.
Match the board depth to the cavity and performance target. Fit boards tightly with staggered joints where the system requires multiple layers.
Standard infill for partitions, ceilings, service rooms and space-limited cavities.
Deeper insulation for thicker walls, facade systems and demanding thermal or acoustic build-ups.
Product specification
A clear range for project selection.
Confirm the board grade alongside the complete wall, ceiling, facade or equipment-insulation system.
