How to install ducting insulation wrap
To be wrapped around ducts and to be finished with aluminium tape.
• The 25mm ductwork insulation thickness offers a high level of thermal and acoustic insulation
• Easy to install due to the product being lightweight, flexible and easy to cut
• Can be used with both circular and rectangular ductwork
Ductwork insulation to prevent condensation
Condensation can form on your ductwork due to a difference in the temperature of the air travelling through the duct and the temperature outside. This is quite common when you have ducts passing through cold areas like loft spaces. Insulation works because it is very inefficient at transferring heat. By installing insulation to your ductwork, condensation will not form because the warm, moist air will not come into direct contact with the cold ducts.
