A Mass Loaded Vinyl used in Floor & Wall Applications

STOMP acoustical shielding is a limp, high density vinyl sheet material, formulated from environmentally friendly, ethylene vinyl acetate (EVA). STOMP is a high quality, cost effective sound damping material designed to reduce sound transmission.

STOMP is designed for use in both floor and wall applications to reduce both impact and airbourne noise. It is appropriate for commercial, industrial, and residential applications.


  • For use in walls directly behind gypsum drywall; and in flooring applications directly under carpet, vinyl, tile, wood, laminate, and resilient floorings
  • Dampens sound and blocks noise by up to 75%
  • Easy to install – reduces labor and production costs
  • Thin profile saves material and labor with no added extensions or adjustments
  • Improves HVAC efficiency
  • One layer improves STC rating by 7 i typical wood and steel studded assemblies (16″ o.c., R13 batt insulation, and 5/8″ gypsum drywall)
  • Classified by Underwriters Laboratories, Inc. as to ANSI/UL 263 standard, fire Tests of Building Construc tion and Materials, UL File CLBV.R39387
  • UL Classified in fire resistant wall designs of the U300, U400, and V400 series
  • UL Classified for use in floor-ceiling constructions of the L500 series

Position STOMP with black side down onto the floor for hard surfaces such as ceramic tile or wood flooring. Position STOMP with black side facing up for installation of vinyl or resilient flooring. Place edge to edge multiple sheets of STOMP to complete the coverage of the room being treated.

Add desired flooring on top of STOMP as per recommended installation techniques. Carpet and vinyl layers can go directly on top. Wood floors can be nailed directly on top. Laminate floors can be floated directly on top. Ceramic and other hard tile surface floors can have the adhesive compound added to the top surface of STOMP, then add ceramic tile to complete the job.

For ceramic and other hard surface tile floor installations, be sure to use an epoxy-fortified adhesive and grout system.

Place STOMP sheet in position at top of the wall. Align vertical edges over center of studs. Insert staples along top edge of sheet to hold in place. Allow STOMP to unroll vertically along the height of the wall. Apply additional staples along vertical edge if desired. For each additional sheet of STOMP to be installed, repeat the previous procedure. Note: Ensure vertical seems are centered over studs. Trim sheet if necessary. Locate any wall outlet penetrations that will require access and cut an X access point for each. Caulk floor, ceiling, and corner joints before installing drywall.

Steel Stud Installation … For installation of STOMP sheets over steel studs, follow installation procedures for wood studs and replace staples with self-tapping, flat head metal screws.
