General Product Details

Protecta FR ASF is designed to prevent the spread of fire, smoke and gases through openings in fire rated walls and floors, specifically linear joints and openings for building service penetrations. Protect FR ASF should be applied over suitable backing materials to ensure correct width to depth ratio and reduce the joint’s shrinkage during hardening. In areas with a high degree of humidity and/or in joints with excessive movement, use Protecta FR IPT.

Protecta FR ASF is a 2 hour rated intumescent sealant formulated with fillers that provide noise reduction. Protecta FR ASF cures when subjected to atmospheric conditions; however, it will retain a small degree of elasticity for joint movement. Under fire exposure, Protecta FR ASF creates a robust fire seal by the formation of a durable intumescent char.

The sealant has undergone tests to BS EN 1366-3 with additional guidelines from BS EN 1366-4 for fire protection joints and testing in accordance with BS EN ISO 140-3:1995 for acoustic performance.
