Certificate of Constancy of Performance: 1488-CPR-0678/W

Declaration of Performance: 81400

Fire resistance class up to EI 120.

The mcr Dunaseal sealing unit is designed for fire sealing  construction gaps and expansion joints with a nominal width of 10÷100 mm. It permits up to 50% movement of parts.

The mcr Dunaseal sealing unit consists of foamed polyurethane layers coated with fireproofing intumescent laminate strips, which expands during a fire, thus creating a fire barrier by filling construction gaps and expansion joints. The placement of the unit in a gap quickly and effectively establishes a fire protecting sealing in a wall, ceiling or at the junction of two construction components.
