40mm Rockwool Ductwrap Foil-Faced Roll

40mm Rockwool Ductwrap delivers superior thermal and acoustic performance for ductwork applications. This lightweight, flexible insulation roll features reinforced aluminum foil facing, perfectly suited for both circular and rectangular ducts. With a maximum service temperature of 230°C, it's the ideal choice for air conditioning systems, warm air distribution, and extractor ducts in plant rooms, boiler houses, and external installations.

The mineral wool core provides outstanding thermal insulation alongside exceptional sound dampening. When ducts transport gases, fluids, or particle solids at high velocities, this combination significantly reduces noise transmission, delivering a quieter, more productive workplace.
