About the words fire rated
The phrase fire rated can be read as a promise that a panel carries a particular tested rating. This site does not use it that way. On this site, fire rated is a category title that gathers buyers looking for fire-related panel performance, and the only fire statement behind the title is the catalogue description of the machine-made rockwool panel as A1 grade fireproof rockwool, plus the general description of rockwool as a non-combustible core material. If a project requires a specific tested rating for a wall system, that requirement must be stated in the inquiry and confirmed for the exact panel variant, joint and fixing arrangement.
Panels behind this title
The panels are the handmade rockwool panel, Type 50, with thicknesses of 50 mm and custom options of 75 / 100 mm, and the machine-made rockwool panel, 1150 type, with thicknesses from 50 mm to 150 mm. Both use rockwool densities in the 60–120 kg/m³ catalogue range. The fire wording is not a reason to skip the other selection steps: thickness, density, joint and area must still be specified for each wall and ceiling run.
