Fabric expansion joints have distinct advantages as they can accommodate relatively large movements and even some misalignment of flanges. They are also lightweight, easy to install and with the addition of internal insulation bolsters have good acoustic properties. Fabric expansion joints can be supplied fully assembled and fitted to support steelwork ready for insertion into ductwork. For retrofit applications, we can supply as factory joined or open for on-site joining where access is limited
