The 24-in x 36-in joist lining seals the underside of floor joist space, creating a duct run to channel air back through the air return system. For ease of use, the panning features a 16-in width equal to the distance of joist spacing. This allows you to nail or screw the lining directly into the wood, creating a run of rectangular duct.
The panning lining is constructed from 30-gauge galvanized steel for rust resistance and lasting durability. It can be cut to size to fit a variety of applications, and is easy to install with sheet metal screws for a secure fit (screws sold separately). This joist panning lining is suitable for use in most heating, venting and air conditioning applications.
