Lindab has a new spin on duct sealing. SPIROsafe round duct includes a double-lipped EPDM seal that eliminates the need for additional sealants, such as tape or mastic. Extreme temperatures and moisture have no effect on installation. Installers simply slip the ducts and fittings together--greatly reducing labor costs (and mess). The seal created by the factory-installed, EPDM rubber gaskets exceeds SMACNA Leakage Class 3 requirements from +12"WG to -20"WG without additional duct sealants. The gaskets are also tested in accordance with ASTM E84-91a (aka NFPA 90A) for conformance with flame spread (FS) and smoke development (SD). SPIROsafe gasket material is UL classified with ratings of FS=0 and SD=5. The SpiroSafe product line includes a full selection of singlewall and doublewall spiral duct, elbows, Y-branches, reducers, tees, end caps, saddle taps and other fittings.
