FiloSeal+HD Fire is a fire resistant universal re-entering duct sealing system, for duct openings of up to Ø 250mm
Easily seal cables and pipes in ducts, drilled holes or transit frames.
FiloSeal+HD provides a strong support system using hexagonal tubes made using a specially formulated material called Formite. These build up like a honeycomb structure. The unique design of the hexagonal tubes makes positioning and separation of the cables very simple while also providing a strong backing for MD+ to be applied. FiloSeal+HD Fire is suitable for sealing 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.
Most importantly, FiloSeal+ HD Fire offers up to 4 hours fire resistance in ducts.
You will need to use MD+ sealant with FiloSeal+. This is easily applied from a skeleton gun. After application and full curing the MD+ forms a plastic elastomer mass with special qualities, effectively sealing and bonding, while providing a high level of durability.
