Light thickness

Light thickness decoupling material gives an air space detachment between the

funnel or pipe and the outer surface boundary cladding. This decoupler material is

ordinarily defined to be light thickness fiber glass with at least 1" (25 mm)

thickness. Thicknesses more noteworthy than 1" offer enhanced abilities up to a

commonsense maximum cutoff of roughly 2" to 3" (50 to 75 mm). The decoupler

material needs to be light and permeable as it is the air caught inside the material

which fills the need of acoustically dividing the divider of the channel or conduit

from the outer surface hindrance cladding
