Sound DampeningHeatshield HP db Shield™ Sound Insulation

Heatshield Products db Shield™ is a thin, lightweight, and highly moldable vibration dampening material that consists of vinyl-based sheets that can mold and conform to irregular surfaces to achieve 100% bond, maximizing dampening performance. db Shield™ will stretch up to 40% to make an irregular surface appear as if it has been dipped in plastic. Twice the dampening and less than half the weight of asphalt dampening material, yet able to handle continuous temperatures up to 250 Deg F.

db Shield™ consists of a proprietary component blend in a lightweight vinyl carrier that has been engineered to convert structural resonance into low-level heat through friction. The friction is created from the proprietary components coming into contact with each other as the panel vibrates.

db Shield™ is ideal for creating or replacing the vapor barrier behind your interior door panels. Denser and more rugged than the flimsy plastic provided by the OEM's, db Shield™ can serve as the vapor barrier as well as a sound barrier in these locations. It will even block speaker back-wave, preventing an acoustical short circuit, while giving your speakers a cleaner, crisper sound.

Heatshield db Shield™ Uses:

Heatshield db Shield™ Installation:

1. If available, use the existing door panel/interior panel as a template. If not, make a template from poster board.
2. Roll out the db Shield™, place the template on the black side and trace onto the shield. Cut 1/4" in from the line to ensure no excess material sticks out from interior panels once reinstalled.
3. Measure and note the locations of wire harnesses, linkages, door panel mounting holes, and where they will pass through the damping sheet. Mark the locations on the db Shield. Cut the openings for these components using a knife or hole saw (for larger openings). Pro tip: Set drill in the reverse direction, cutting slowly in reverse will produce a clean cut and prevent tearing of the db Shield™.
4. Clean the surface of the body panel or door by cleaning and degreasing them. Give the panel one final wipe with isopropyl alcohol or aerosol glass cleaner to remove unwanted residue.
5. Grab the db Shield™, pull down the white release liner paper approximately 3" and position the sheet starting on one edge of the body panel or if installing on a door, start with the top and work down. Be sure it is centered!
6. Using your palm, bond the sheet to the door all the way across the top. Use the heat gun to allow the material to mold and conform to any irregular surface that may be present. Make the db Shield™ warm, not hot.
7. Continue to install the sheet by hand, pulling the release liner down 4" to 6" at a time and working from the top of the door down, and then from the center of the db Shield™ to the outside edges. Work on small sections at a time (6" x 6"). A heat gun will allow the material to stretch and conform to irregular surfaces.
8. Any pockets of trapped air are easily removed by cutting a small hole at the edge of the bubble, heating slightly with the heat gun, and then using your fingers to force the trapped air out of the hole.
9. The material will stretch and there will most likely be excess at the bottom. Using the opposite door as a reference, estimate how much will have to be trimmed off of the bottom before it is bonded to the surface of the door.
10. If you have accidentally covered any of the door panel fastener mounting holes or other openings carefully cut out the excess material directly over the opening. Pro Tip: Use a heat gun to warm covered opening will help with removal.
11. Excess db Shield™ may be used to tape down wire harnesses if necessary.
12. If painting or taping, be sure to clean the surface of the body panel or door by cleaning, and give the db Shield™ one final wipe with isopropyl alcohol or aerosol glass cleaner to remove unwanted residue.
13. If you need to remove the db Shield™, a heat gun may be necessary. Start in one corner, and use a plastic scraper, work your way outward. To remove any adhesive from the panel, wipe with a cloth soaked in WD-40.
14. Done!
