PU edge-sealed rock wool panels
A PU edge-sealed rock wool panel has a non-combustible rock wool core with polyurethane foam at both edges. The PU seal makes the joints tighter and improves insulation and water resistance, while the rock wool core keeps the fire performance.

- Factory and warehouse walls that need a fire-rated core
- Cold-chain and food buildings that need tight joints
- Roofs where rock wool fire performance and better joint sealing are both required

Questions
How is it different from a normal rock wool panel?
The edges are filled with PU foam instead of rock wool, so the joint closes tighter and stops air and water better.
Is the panel still non-combustible?
The rock wool core is non-combustible; request the test report for the exact panel assembly your project needs.
