For sale - partial roll of Soundown Marine Carpet Underlayment, 1/2" thick, 1 lb per square foot. We bought the roll this summer when we replaced carpet on our boat. See the link below for description of the material. Great for reducing noise in salon above engine room.
Soundown - Barrier Acoustic Insulation, Carpet Underlay, Acoustic Absorption Materials
Roll is 4.5' wide, we have approx 38 linear feet left - so 171 square feet.
Offering at $8 per square foot - $1368 for the whole roll. You won't find a better price.
Will consider cutting pieces, but at a correspondingly higher price. We got a quote from a local supplier for $10.44 / sf for this same material plus $25 for a less than full roll quantity.
Not sure of how feasible it would be to ship this - bulky, heavy roll.
We are in Seattle.
