Fischer Firestop foam is a single component, self expanding polyurethane foam which has been designed to be self curing via the absorption of moisture from the atmosphere. The foam has excellent adhesion properties and can adhere to most building materials, when the foam sets it cures to a semi-rigid structure which accommodates low movement and vibration. Tested to the DIN 4102, BS 476 and EN1366-4 the firestop foam also exhibits excellent thermal properties and helps to maintain the sound reduction index of a structure. Services penetrations should be adequately protected with suitable firestop material such as : FiAM Intumescent Acoustic Mastic, UFS universal Firestopping sealant, FiGM Intumescent Graphite Mastic, FFC Collar or FiPW Pipe Wraps, and should be installed in accordance with detailed instruction or approved system.Applications:Construction joints in walls and floors Insulating and sealing doors and windows - non-fire rated application Backfilling material only for service penetrations Filling general voids and cavities - non-fire rated applicationAdvantages:High foam yield No post shrinkage or expansion CFC free - Propellant Effective seal against smoke Can be rendered, cut, painted or sanded High bond strength Good adhesion to most building materials Excellant Acoustic and Thermal PropertiesSuitable for:Concrete Masonry Steel - as backing material Timber - as backing material
