A1 fire class / acoustic and thermal insulation
Glass Fiber Wool
Lightweight porous insulation made from fine glass fibers. Its open fiber network absorbs sound energy, limits heat transfer and fits cleanly inside framed walls, ceilings and equipment enclosures.

Porous fiber structure
Small air paths. Broad acoustic control.
Sound entering the fine fiber network is repeatedly scattered and converted into very small amounts of heat. Installed behind a finish or within a cavity, the material reduces reflected sound while also adding thermal insulation to the complete assembly.

Verified performance direction
Non-combustible protection with high acoustic potential.
The inorganic glass-fiber composition supports A1 non-combustible classification. Depending on density, mounting and test configuration, reference acoustic data can reach NRC 0.96 across a broad 100-5000 Hz range.
Density selection
Four grades for different system demands.
Density affects rigidity, handling, acoustic behavior and the way the panel is retained inside the assembly. Select it together with the facing and cavity design.
Lightweight infill
General ceiling and partition cavities where efficient coverage and easy handling are priorities.
Balanced acoustic grade
A versatile density for meeting rooms, offices and educational interiors.
Higher-density control
Greater material mass for demanding wall, ceiling and equipment-room assemblies.
Heavy acoustic grade
Dense infill for specialist enclosures, studios and industrial noise-control systems.
System build-up
Hidden inside the assembly. Essential to its performance.
Glass fiber wool is normally retained between studs, channels or hangers and covered by a suitable decorative or protective facing. Tight joints and continuous coverage help avoid acoustic and thermal weak points.
- 01Supporting frameWall studs, ceiling channels or project-specific steelwork define the cavity.
- 02Glass fiber woolPanels are fitted closely between supports without unnecessary gaps.
- 03Facing layerPerforated acoustic panels, gypsum board, fabric or metal finishes complete the system.
- 04Joint continuityEdges, penetrations and service zones are coordinated to maintain coverage.
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.
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.
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.
Product specification
A clear base module for project detailing.
Use the standard panel dimensions as the starting point, then choose density according to the acoustic, thermal and installation requirements.
