There’s a shortage of labor in the commercial construction market; this has elevated the need to reduce as much job site labor as possible.  For the HVAC contractor, one of these job site tasks is the sealing of the Snaplock Pipe . It’s almost always done with bucket and brush in the air. The appeal of the Greenseam Plus is that it is a presealed Snaplock Pipe on both the longitudinal and transverse connections eliminating the need to seal the pipe . Once it’s hung, it’s done…and thus the labor and material costs typically required for duct sealing are removed.
