Intumescent expansion joints are a composite, compressible, and foil-clad intumescent strip. Unaffected by water or chemicals, they are easily installed, and are available in three types widths and lengths. Useful as movement or expansion joints in fire walls, floors, concrete slabs, and steel work, or as a cavity joint between brickwork and timber structures. They can be used around ventilation ducting as a movement and anti-vibration joint, using double-sided tape to adhere to the ducting, and can also be fitted to seal over the tops of cable trays passing through protected building elements.
- Extremely versatile, providing up to 240 minutes protection in a range of applications, for example:- As movement or expansion joints in fire walls, floors, concrete slabs and steelwork
- As a cavity joint between brickwork and timber structures
- Around ventilation ducting as a movement and anti-vibration joint
- As a seal over the tops of cable trays passing through protected building elements
FIRE TEST PERFORMANCE
Tested to BS476 Part 22 (1987), sealing horizontal and vertical expansion joints of different widths, achieving integrity and insulation results of up to 240 minutes.
Tested at VNE to European Standard EN13504-2 (2004).
Made in a range of sizes to suit gaps up to 120mm wide, the expansion joints are easily installed giving protection to both horizontal and vertical gaps. Simply compress into narrow gaps or apply to one side of a wider gap, using double sided tape on one face to adhere in place. The sponge and intumescent expansion joint allows for movement but, in the event of a fire, will completely fill the gap.
