Rockwool Density Selection
Rockwool density selection: the 60-120 kg/m3 catalogue range for handmade and machine-made rockwool panels, with an inquiry checklist and no performance conversion.
- Catalogue density range for both rockwool routes: 60–120 kg/m³, set to customer requirements.
- No density-to-performance conversion table is given on this site.
- Density is only one selection item; route, thickness and joint must also be specified.
The density range, and what it does not decide
Both rockwool routes on this site use the same catalogue density range: 60 to 120 kilograms per cubic metre, set to customer requirements. That range is a specification input, not a performance result. This page does not state that a higher density gives a particular sound reduction, fire duration or insulation value, because the company materials used for this site give no table that converts density into those results. Treating density as a proxy for performance would invent a relationship that the source does not support, so this site refuses that shortcut and instead gives buyers a checklist for asking the right question.
Density checklist by room
| Question to answer | Why it matters |
|---|---|
| What is the room used for? | Production, laboratory and food rooms place different demands on a wall, even at the same density. |
| Which panel route and thickness are under consideration? | Density interacts with route and thickness in the finished panel; it cannot be chosen alone. |
| Is sound, fire or heat the driving requirement? | The driving requirement decides what documentation to ask for, not just which density to pick. |
| What density can be supplied for that exact variant? | Confirm the density for the route and thickness ordered, not for rockwool in general. |
The parallel density guide in the guides section explains the same range in article form. Before ordering, confirm the minimum order quantity and the lead time in your inquiry, and before payment confirm the density, thickness and joint type in writing.
