TMSoundproofing's Pipe and Duct Wrap / Lagging is a multi-purpose composite material featuring a flexible, acoustic  Foil Faced Mass Loaded Vinyl Barrier laminated to an insulating and acoustic Quilted Fiberglass decoupler on one side. The fiberglass, available in 1" and 2" variations is bonded to the inside of the acoustic barrier to provide thermal and vibration insulation. The combo forms a thin, lightweight acoustical product that displays excellent mechanical properties while providing superior sound transmission loss. Fire rated and can be used in many applications.

How it Works:

Sound waves originating from the source will be initially absorbed by the fiberglass and then blocked by the mass loaded vinyl. Any reflected sound wave component will be further dissipated into the fiberglass absorber.


  • Combines noise barrier and sound absorption
  • STC rating beginning at 29, see Data Sheet
  • 1 LB or 2 LB MLV options
  • 1” or 2” Thick Fiberglass options
  • 135 or 67.5 Square Feet rolls, see above
  • Scrim Reinforced Foil Finish on one side
  • Fire Rated

Suggested Applications:

Wrap noisy pipes, waste pipes, ducts, valves and fan housings to prevent break through noise from transmitting through the wall of the pipe or duct. When applying, cut the length from the roll, wrap around structure, overlapping around 5" at seams and tape closed with duct or mylar tape.

How to Order

Can be purchased with 1 LB or 2 LB MLV and a choice of 1” or 2” Fiberglass, select from options above. Square Footage per rolls are as follows:

1 LB Barrier with 1" or 2" Fiberglass - 4.5' x 30' Roll (135 Square Feet)
2 LB Barrier with 1" or 2" Fiberglass - 4.5' x 15' Roll (67.5 Square Feet)

To determine the amount needed: measure length and diameter of structure. Add 5" to diameter to allow for overlap.

Customers Questions and Answers

1) Lottie : I have one noisy steam heat pipe in my apartment that I want to wrap, and it looks like this is the right product for the job. However a 4-4.5' x 30' roll is way more than we need! Is there any way to get a smaller piece? (The pipe is about 4" diameter and 12' long) Thank you so much, Lottie

Trademark Soundproofing Reply:

You can try the ceiling tile barrier which is the same material just cut in squares

2) Devon S: Would this be a good choice to stop vocal/music sound from transmitting through our duct work?

Trademark Soundproofing Reply: If the sound in entering or exiting through the closed part of the duct work, then yes. If it is going through the open vents at both ends than not.

3) David W: Is this product fire rated for 1 hour? Thank you

Trademark Soundproofing Reply: It is not tested to that. It is tested to has only been tested to ASTM E-84, which is a flame & smoke generated test.

4) Marc L: Hi! It is possible to order only one roll to test it? Also, how much shipping to send it near Montreal in Canada? Is it free shipping if I order two rolls? Thanks! Marc

Trademark Soundproofing Reply: Hi Marc. Please email for help.
