FiloSeal+HD FIRE
Duct sealing system FiloSeal+HD FIRE is our new highly certified fire, gas and water sealing system for both ducts and transit frames.

• Up to 4 hours fire resistance in transit frames (single side)
• Up to 4 hours fire resistance in ducts
• Tested to BS EN1366-3 2009
• Upto 2 bar Pressure Resistance
• 100Kg pulling Force on the cables when sealed
• 10xd at 45º, with 1 bar pressure bending test

FiloSeal+HD FIRE provides a strong support system using the fire resistant hexagonal blocks made of our specially formulated material called 'Formite' which builds up like a honeycomb structure. FiloSeal+HD FIRE is suitable for sealing empty or any cable configuration or pipes contained in one duct and also allows easy re-entry of the seal to add or remove cables or pipes as required.

The Filoform duct sealing system FiloSeal+HD FIRE uses our fire resistant MD+ sealant which is easily applied from a skeleton gun. The high quality, one component, flexible sealant “MD+” is based on a silicon compound that cures with air (Humidity).

After application and full curing the thixotropic MD+ forms a plastic elastomer mass with special qualities effectively sealing and bonding, while providing a high level of durability.

FiloSeal+HD FIRE is very easy to apply regardless of the type of cable scenario in the cable ducts as it uses strong, but flexible hexagonal blocks to support the cable and provide a strong backing for the seal.
