Why every Duct Fab Shop should have cans of Edge Coating on hand when cutting and installing Fiberglass Duct Liner
With the quality of workmanship involved in creating duct sections and fittings, many shops have found it’s worth taking the time to grab an aerosol can of DURO Dyne Edge Coating and coat the raw ends of Duct Liner. Job sites are dynamic places, having an single can of Duro Dyne Edge Coating vs the old standard of field guy carrying around a heavy gallon of duct sealer to paint onto the frayed ends of fiberglass is a much more effective use of labor. Not only would they do it faster in the shop with a spray can, they would match the black color of the Liner surface.
If you had the task of coating these four edges and given the option of a bucket of duct sealant and brush vs an aerosol spray can, which would you choose?
There’s no argument that Internally Lined Rectangular Duct is the only way to achieve the highest levels of Acoustical performance in a Duct System. Externally wrapped Duct not only covers up the workmanship behind well made Rectangular Ductwork: it also does very little to control the noise that carries thru a Duct System. That said, Engineers are on the “no Fibers in the Airstream” mode despite significant advances in the airstream surface from manufacturers like Johns Manville, Owens Corning, and Knauf. But Duct Fab shops are doing Fiberglass Liner no favors if they aren’t still going that extra step to ensure that any loose fibers caused from processing the Liner aren’t visible to the inspectors.
Products like Edge Coating are great accessories to have on hand and can really make a difference in the appearance and ensure that handling doesn’t shake out more fibers from the inner core of the Duct Liner.
Try Duro Dyne’s Edge Coating; it’s worth the expense of the can 10x over.
