Ryanfire 502

Ryanfire 502 board is a high density rock fibre board coated on both faces with Ryanfire Mastic, an ablative fire resistant acrylic coating. The coating provides additional protection to the stone wool core and prevents the passage of hot gasses thereby reducing heat conduction.
The 502 board must be used together with Ryanfire Mastic for sealing around penetrating services and supporting construction elements.
Ryanfire 502 board is manufactured under controlled factory conditions to detailed thickness and specifications.
