SOUNDPROOFING BARRIER MATS

SAPT220 Sound Barrier Mat

Spaced Layer Sound Barrier Mats

Applications

Spaced Layer Sound Barrier Mats employ self-extinguishing components and are primarily intended for the improvement of the sound insulation of sheet metal that resonates above 350Hz. These barrier mats are particularly useful for soundproofing and insulating pipes, ducts, vehicle bulkheads, hoppers and machinery enclosures.

General Description

These soundproofing barrier mats resemble the monolayer barrier mats except that the reinforced backing is replaced with a layer of sound absorbing acoustic foam. Although usually available with a scratch resistant coating, the product can also be supplied without it.
