Intumescent, joint-sealing unit
Dunaseal – for a moving joint
Dunaseal joint sealing unit consist of hard-to-burn, one-, two- or even multi-layered elastic sponges, with a corresponding number of intumescent laminate layers, which, in the event of a fire, fill fixed and moving gaps, construction dilatations and prevent further spread of the fire due to their large and rapid increase in volume. Placing the units in the gap allows you to quickly and effectively create a fireproof seal in the wall or slab, or in gaps where two structures meet. Thanks to its flexibility, it enables the independent movement of the elements of the structures, while maintaining complete airtightness.
