Protection of rectangular and square steel ductwork.
Insulating ductwork can be beneficial for reducing thermal transmission as well as protecting the structure in the event of a fire which can amount to costly damages. ROCKWOOL FIREPRO® DuctRock® Slab can provide up to 2-hours’ fire protection to ductwork in addition to fire resistance where they pass through fire rated walls and floors. This provides assurance that fire cannot spread unseen through ducting around a building.
FIREPRO® DuctRock® Slab is composed of high density, non-combustible mineral wool insulation, finished with a high emissivity black foil facing. FIREPRO® Glue and high performance Black Aluminium Foil Tape are available for sealing all board joints. The ROCKWOOL 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.
DuctRock Slab has been tested in accordance with BS EN 1366-1 for ventilation ducts and BS EN 1366-8 for smoke extract ducts
