Sealmaster FireFoam


Where large gaps exist between the door frame and wall construction, conventional intumescent seals may not always be appropriate. In such cases Sealmaster FireFoam can be used to maintain the integrity of a fire compartment. It is also suitable for filling in around ducts and other service penetrations.

FireFoam is an intumescent, dry foam joint filler which is quickly and easily fitted, requiring no adhesive or surface preparation prior to use. It is flexible and will accomodate movement, yet is durable and resistant to extreme environmental variations.

Sealmaster FireFoamAPPLICATIONS
FireFoam has three main areas of application:
• Expansion joints and other linear joints.
• Around ducts or service penetrations.
• Between door frames and structural openings.

On activation the fire resistant foam degrades and the volume is replaced by an expanding mass of intumescent graphite which prevents the passage of smoke, flames and hot gases

Independently tested to BS 476: Part 20: 1987 to give up to 4 hours depending on the width of the gap and depth of FireFoam.
