Weatherproofing through-roof flues and ducts Through-roof flues and ducts come in a wide range of shapes and sizes, and whether you need to install a round, square, or rectangular flue or duct, weatherproofing is a key consideration. The in-situ weathering system from Jones and Woolman UK comprises a fibre-reinforced cold-applied liquid that provides project flexibility and reliable weatherproofing. It’s ideal for applying on roof penetration projects, such as through-roof flues and ducts, to ensure precipitation and wind are kept out of the building envelope. If you’d like to learn more about how to effectively weatherproof a through-roof flue or duct in a built-up roof, take a look at our technical drawing, which you can download below.
