FIREPRO® Glue and high performance Black Aluminium Foil Tape are available for sealing all board joints. The DuctRock® Slabs are readily available in three thicknesses, are easy to handle and simple to install. The slabs can be installed using stud welded pins, steel washers and FIREPRO® Glue, and are easy to cut with a hand saw or circular/table saw.
DuctRock® Slab has been tested to the latest harmonised European standard and is capable of achieving a fire resistance up to EI 120, up to 2-hours’ fire protection for rectangular ventilation and smoke extract ducts and up to 1 hour fire protection to ducts with a combustible lining (kitchen extract) ducting. The solution is typically used in commercial and industrial settings where they travel throughout the building passing through fire rated walls and floors.
