Mass loaded vinyl typically costs $1.00–$2.50 per square foot for 1 lb material, with 2 lb MLV running $2.00–$4.00 per square foot depending on roll size and supplier.

Price scales with weight per square foot — heavier mass loaded vinyl uses more mineral loading, which drives up material cost. Buying in larger rolls (100–200 sq ft) generally reduces the per-square-foot price compared to smaller cuts. Composite products like a fiberglass-decoupled MLV wrap sit at the higher end of the range because they combine two functional layers — an acoustic barrier and an absorbing decoupler — in a single assembly.

  • 1 lb mass loaded vinyl: typically $1.00–$2.50 per square foot at standard roll quantities.
  • 2 lb mass loaded vinyl: typically $2.00–$4.00 per square foot, reflecting higher mineral loading.
  • Soundsulate 1 lb MLV achieves STC 27 on its own; the LAG fiberglass composite reaches STC up to 29.
  • MLV is sold by the square foot or in rolls; common roll sizes range from 20 to 200 square feet.
  • Foil-faced fiberglass decoupler composites (LAG-style) carry a Class A rating per ASTM E84, which affects commercial project eligibility.
