Ductwrap by Rockwool is specially made to prevent heat loss in ducts. They are made of mineral wool and have factory-applied foil-facing on the outer side. They give superior thermal insulation to ducts, cold water storage, feed and expansion tanks. It soundproofs ductwork leading to a quiet and more productive workplace. Ductwrap also gives superior fire resistance and is non-combustible. They have the highest possible fire rating A1 by Euroclass. They can be used to insulate all types of ductwork in the H&V network. 

Rockwool Ductwrap is the cheapest duct insulation out there, with no compromise to quality whatsoever. When installed correctly, ductwrap prevents any air leakage from the ducts whilst also restricting the entry of pollutants into the H&V system. They optimise the ducts' performance, which in turn helps make the building more energy-efficient. Foil facings in this ductwrap insulation give continuous protection against moisture. They also help keep problems like condensation and duct sweating to a minimum. 

Ducting insulation helps improve indoor air quality. A properly installed ductwrap with appropriate service labels improves workplace safety. Rockwool Ductwrap saves energy and is chemically inert. It is rot-proof and does not support the growth of moulds, fungi etc.
