Rock Wool Board
Rock wool board insulation provides dense, non-combustible mineral wool in rigid panel form for facades, ceilings, acoustic panels, and industrial equipment. Density from 40 to 200 kg/m³, thicknesses from 20 mm to 200 mm, fire classification up to Euroclass A1, with thermal conductivity from 0.033 to 0.042 W/m·K — confirm exact grade and documentation by inquiry. Supplied from our own and partner factories — combined capacity up to 450,000 t/yr, with a one-container MOQ and LCL support.
- Dense, non-combustible mineral wool provides compressive strength for facades, roofs, and equipment surfaces where glass wool boards compress and deform.
- Better low-frequency acoustic absorption than lightweight boards — the standard for acoustic partitions, studios, and equipment enclosures.
- Dimensionally stable under cladding loads, fastener pull, and roof traffic that crush lighter insulation materials.

Problems This Product Solves
Common pain points this product is built to address.
Facade panels warp or sag when the insulation board cannot hold its shape under cladding.
External wall insulation systems (ETICS, ventilated facades) need rigid panels that resist wind suction, gravity, and temperature cycling without deforming. Rock wool board provides the dimensional stability that blankets and batts cannot.
Acoustic ceiling grids need boards with precise, consistent edges — not flexible cavity fill.
Lay-in ceiling tiles and clip-mounted acoustic panels require boards cut to exact dimensions with clean edges. Rock wool board is manufactured in rigid panel format that drops into grid systems.
Industrial equipment panels must resist compression under metal cladding without crushing.
Metal jacketing applies point loads at fastener locations. Rock wool board at suitable density withstands cladding compression while maintaining thermal performance — a requirement that low-density batts cannot meet.
Fire-review requirements demand non-combustible rigid panels with documented classification.
Fire-rated wall and ceiling assemblies require insulation with tested fire classification (Euroclass A1). Rock wool board provides non-combustible rigid panels with fire documentation for system approvals.
Engineered for Consistent Performance
Every batch is produced under controlled conditions and verified against international standards, so what you specify is what you receive — project after project.
Product Benefits
What sets this product apart in real projects.
Dimensional stability under wind and thermal cycling
Facade and cladding systems stay aligned over time without insulation movement causing panel gaps.
Compressive strength at density
Supports under-cladding installation, traffic floors, and equipment panels without crushing at attachment points.
Non-combustible mineral fiber
Meets non-combustible classification for fire-review documentation routes in commercial and industrial projects.
Precision-cut edges for facade and ceiling systems
Reduces on-site trimming and provides clean board-to-board joints in visible or system-critical installations.
Higher temperature service range than glass wool
Suitable for equipment panels and industrial applications where operating temperatures exceed glass wool limits.
Acoustic absorption at density
Provides sound absorption performance for ceiling panels, partition systems, and acoustic wall assemblies.
Best-Fit Applications
Rock wool board is most commonly used where a rigid mineral wool panel is needed for thermal, acoustic, fire-review, or compressive-load conditions.
External wall facade systems (ETICS / ventilated)
Dimensional stability and non-combustible classification suit facade insulation under cladding or render.
Flat roof insulation
Compressive strength at density supports roof traffic and mechanical loads above the insulation layer.
Acoustic ceiling panels
Precision-cut edges and acoustic absorption fit lay-in ceiling grid systems.
Industrial equipment panels
Higher temperature range and compression resistance suit panels under metal cladding on tanks, ducts, and process equipment.
Fire-rated wall assemblies
Non-combustible mineral fiber supports fire-review documentation for commercial partition and wall systems.
Floor insulation under screed
Board rigidity and compressive strength handle screed load without long-term deformation.
Options & Variants

Foil Faced Board
Foil facing — vapor barrier and thermal reflection on the surface.
Black Tissue Faced Board
Black tissue facing — finished dark face for lay-in ceilings.
Unfaced Board
Bare board — to be covered by a jacket or building system.

When It's Not the Best Fit
Rock wool board is not the best first choice for every insulation condition. Review the project before using rock wool board when:
Selection Guide
Answer these to narrow down the right specification.
What is the application: facade, roof, ceiling, equipment, floor, or wall assembly?
Confirms whether board is the right product form and narrows the variant option.
What board size and thickness are needed?
Helps match the board to the installation area, build-up depth, and thermal target.
What density is required?
Determines compressive strength, acoustic behavior, and handling weight for the application.
Is a facing or coating required?
Selects between unfaced, foil faced, black tissue, white mineral coated, or dual-density routes.

Frequently Asked Questions
Answers to common questions about this product.
Rock wool board can be a component of fire-rated wall assemblies, but the fire rating belongs to the tested system — not the board alone. Confirm the complete assembly documents.
Higher density provides better compression resistance and low-frequency acoustic performance. Lower density is lighter and easier to handle. Confirm from the datasheet for the specific application.
Rock wool board is not waterproof. It is water-repellent to varying degrees, but should not be exposed to sustained moisture without drainage and protection.
Choose rock wool board when the project needs higher density, compressive strength, higher temperature tolerance, or non-combustible fire documentation. Glass wool board is lighter and lower cost for moderate applications.
Facing options may include foil, tissue, mesh, or other materials. Confirm availability, fire behavior, and compatibility with the application.
