The fabric expansion joints can also be designed to bridge between round and rectangular ducts.
Combination type expansion joint configuration whether the duct cross sections are round or rectan gular with rounded corners the fabric expansion joint can be designed accordingly.
Engineered with a leed qualifying zero voc gasket this ductwork can eliminate the need for additional sealing along the longitudinal seams and transverse joint.
A fabric expansion joint is inserted into the ductwork where the movement will occur.
Designs and supplies fabric or non metallic expansion joints for a wide variety of applications.
It has three main components a fabric gas seal membrane gsm insulation and metallic frames.
Designed to your specifications and application requirements holz manufactures high quality flue duct expansion joints for industrial ductwork systems.
A ducting system can be extensive and depending on what materials are flowing through having the right flue duct expansion joint is necessary to prevent leakage lessen noise and vibrations maintain operation and safety stands and reduce the chance of failure.
Movements for a given face to face width are less than other materials.
Fully molded duct expansion joint.
Basic forms of expansion joints.
Flue duct expansion joint flextech engineering inc.
Composite flexible element material for fabric duct expansion joints are have a multi layered design with insulating layers reinforcing plies and vapor barriers with either fluoropolymer or elastomeric covers.
Fabric expansion joints need to be designed with many factors considered in order to ensure a long life.
