Same as 07621 and 07631 with a 1 lb. per square foot loaded vinyl barrier added to stop noise. Used mainly on firewall to stop noise from being transmitted into the cab interior. Also to add a barrier to firewall area inside of cab. Will not absorb water or other liquids. Easy to clean.
Ribs run lengthwise on material.
A barrier material is like a wall that blocks the sound from passing through it. Very few noise problems can be solved by just using an absorption material or a barrier material. More often, both absorption and barrier materials are required. Many of our noise control materials are a composite of both absorption materials and barrier materials. No. when ordering 50 ft. rolls.
