Rock wool · reinforced aluminum foil facing
Foil-Faced Rock Wool Boards
Class A mineral-wool boards with a reflective foil surface for protected acoustic, thermal and service-zone insulation.
- Size
- 1200 x 600 mm
- Thickness
- 50 / 100 mm
- Density
- 60K-140K
Protected mineral insulation
Fire-safe insulation with a durable reflective face.
The dense rock-wool core provides thermal resistance and acoustic absorption. Its reinforced aluminum foil facing creates a cleaner exposed surface, reflects radiant heat and can support vapor-control detailing when joints, edges and penetrations are fully sealed.

Product construction
Two coordinated layers for demanding services.
The board combines non-combustible mineral fibers with a reinforced foil facing. Correct fixing and sealed joints preserve continuity around complex ducts and soffits.
- 01Reinforced aluminum foilReflective, cleanable surface with improved handling and tear resistance.
- 02High-density rock woolPorous mineral fibers absorb sound and slow heat flow within the assembly.
- 03Mechanical retentionInsulation pins, washers or approved framing hold the boards securely.
- 04Sealed foil jointsCompatible foil tape completes edges, penetrations and board-to-board seams.
Performance range
Class A fire performance in five density grades.
Select board thickness and density around the service temperature, fixing method, acoustic target and tested assembly.
Density selection
Choose rigidity to suit the installation.
Density affects handling and board firmness. The correct choice also depends on orientation, support spacing and the complete insulation system.
General insulation
Lightweight board for broad ceiling, wall and service-zone coverage.
Balanced service grade
A practical combination of rigidity, acoustic infill and thermal support.
Robust duct grade
Firm board for ducts, soffits, plant rooms and commercial services.
High-density grade
For demanding mechanically fixed and industrial insulation build-ups.
Specialist heavy grade
Maximum density in the range for selected high-load or high-rigidity systems.
Thickness options
Specify 50 mm or 100 mm.
Choose the insulation depth around available space and project performance requirements.
Compact board for ducts, soffits, ceiling services and space-limited assemblies.
Deeper insulation for larger ducts, plant areas and demanding acoustic or thermal systems.
Product specification
A defined range for coordinated projects.
Confirm the facing, board grade, fixing method and joint treatment together before ordering.
