Duct wraps by Rockwool are specially made with inner mineral wool insulation and an outer foil layer. 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. Duct wraps also give superior fire resistance and are 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. 

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

Ductwrap help improves indoor air quality. A properly installed duct wrap with appropriate service labels improves workplace safety. Duct wrap saves energy and is chemically inert. It is rot-proof and does not support the growth of moulds, fungi etc.
