ROCKWOOL® DuoDuct is a non-combustible stone wool slab that provides thermal insulation to external ducts carrying warm air, chilled air, or dual-purpose duct systems. DuoDuct is a non-combustible, dual-density stone wool slab with an aluminium foil facing bonded to the outer surface. The product is recommended for ductwork with service temperatures up to 230°C. It can also be used in plant rooms, low-level plant work applications, and areas with an increased risk of impact damage. In addition to DuoDuct Slab for rectangular or square external ductwork, ROCKWOOL offer a range of products that are suitable for use on circular external ductwork and this includes: • RockLap H&V Pipe Sections which are suitable for outside diameters ranging from 17-406mm • Pipe Section Mat which is suitable for larger circular ductwork ≥ 406mm It is sometimes desirable to improve the acoustic insulation on duct systems, especially those in which gases, fluids or particle solids are transported at high velocities. The use of ROCKWOOL DuoDuct can considerably improve the level of environmental sound. Durability ROCKWOOL stone wool insulation products have been proven in service for over 60 years, in a wide range of climates and degrees of exposure. ROCKWOOL insulation will generally perform effectively for the lifetime of the building, plant or structure. Biological ROCKWOOL stone wool is a naturally inert and rot-proof material that does not encourage or support the growth of fungi, moulds or bacteria and offers no sustenance to insects or vermin.
