Rectangular ductwork is an alternative to spiral ducting. The ductwork is manufactured in our workshop with a mez flange at each end which connects each item together with a bolt in each corner. This makes the ductwork simpler and quicker to install, greatly reduces leakage and is ideal for kitchen extract systems.
Rectangular ductwork is also used where there are shallow ceiling voids because it can be made to suit the size of the void.
In this section of the site we have made it possible to order simple and commonly used rectangular items online.
