Description
UPC-226-5 is a 2.5" flexible sound attenuator duct insulated to R4. It comes in a box quantity of 5 12' lengths.
Tubing can be cut to length as needed. The Unico sound attenuator significantly reduces sound from the outlets.
The outer jacket for all is made of a two-ply reinforced reflective mylar; providing a vapor seal to prevent leakage and moisture migration and increases the insulation factor by reducing the radiant heat transfer.
