Sound Deadening

• Kilmat Sound Deadening (80 mil)

• Peel-and-stick material

• Applied to interior walls, ceiling, and floor

• Reduce road noise and vibration while driving

• Limit noise inside the van from being heard outside

• Before installing the material, clean all surfaces it will adhere to and treat any exposed metal or rust to prevent future corrosion

• Use a roller to press the material down until the bubbled texture becomes flat

• Remember to remove the door panels so sound deadening can be applied inside the doors too

• Only 25% surface coverage is needed

• I used two boxes (72 sq. ft.)

• The material is relatively heavy

• A slight asphalt smell may be noticeable for a few days after installation

• Apply extra material to the wheel wells since this area tends to be noisier

• Thicker material generally provides better vibration reduction

• If installing in cooler weather, warming the adhesive with a hair dryer can help improve adhesion and ensure the material sticks properly

• FatMat

• Dynamat

• Noico

I did notice a difference in sound once it was installed and would absolutely apply it again in a future build. While sound deadening won’t eliminate road noise completely, it helps reduce vibration and makes the van feel noticeably quieter.
