DRYSEAL FABRIC JOINT MATERIAL


DRYSEAL consists of a PTFE coated fibreglass composite fabric to which has been laminated on one side of the fabric a latest technology gas seal barrier. The composite fabric is the load bearing component. The gas seal barrier is flexible, durable and crack resistant enhancing the working life of the product.

DRYSEAL is generally used as the flexible membrane in fabric expansion joints. The fabric has been especially developed for moderate duty flue gas service. Whilst this product is not recommended for wet acid applications, the gas barrier does provide the fabric with chemical and temperature exposure capabilities.

DRYSEAL fabric can be used as a flat belt or integrated with flanges or pipe hardware to create an expansion joint to absorb movements and misalignments in ductwork. Once measured and cut to suit the application or ductwork, the fabric can be heat seal joined to form a continuous belt.

It is recommended RADCOFLEX construct and assemble any new fabric expansion joints involving hardware.

Replacement fabric membranes can be fitted by the customer in most cases, subject to the complexity of the hardware configuration involved. A Heat Seal Iron, heat sealing film and instructions are available from RADCOFLEX if required.
