Technical planning
Important decisions before quotation
Each part of the system should be coordinated with the other parts, site conditions and the intended operating environment.
Board density and application
Rockwool is available in different densities, thicknesses and facings. Low-density rolls, semi-rigid boards and high-density boards serve different cavity, ceiling, acoustic, roof and industrial applications. Density alone should not be used as the only selection criterion.
Acoustic use
Rockwool can absorb sound within wall and ceiling cavities and can form the core of fabric acoustic panels. Sound isolation still depends on board layers, framing, airtightness, decoupling and flanking-path control.
Fire-conscious assemblies
Stone wool is commonly selected in fire-conscious systems, but the required rating belongs to the complete tested assembly. Boards, studs, fasteners, joints, penetrations and supporting construction must follow approved details.
Handling and installation
Confirm dimensions, compression, support, facing direction, protective equipment, moisture protection and edge continuity. Gaps and poorly fitted pieces reduce the intended thermal and acoustic performance.

Frequently asked questions
Answers before you proceed
Final design, quantities, performance and price require project-specific review.
Talk to the project deskWhat rockwool density should I use?
Density depends on the product format and application. Acoustic panels, partitions, roofs and industrial systems can require different combinations of density, thickness, facing and support.
Is rockwool waterproof?
Many stone-wool products are water repellent, but they should still be protected from prolonged wetting and installed within a correctly detailed moisture-management system.
Can rockwool reduce heat and noise?
Yes. It can provide thermal resistance and sound absorption, but complete heat and sound performance depends on the entire construction assembly and installation quality.
