    Intusleeve seals around plastic ventilation ducting passing through fire barriers and fire compartment walls, with its intumescent lining crushing heat-softened pipes in fires and filling the void to prevent the spread of smoke and fire. The metal duct sleeves fix around ducting and slide into compartment walls, protecting voids and cavities for up to 120 minutes.

    Nullifire Intusleeve PVC Duct Closer is an economical solution for fire sealing combustible ducting penetrations, completely protecting the cavity within stud work walls, and can be retro-fitted to existing ducting.
