Buyer’s Guide: What to Consider
Choosing the right van sound deadening involves balancing thickness, material type, coverage, and adhesive quality. This guide breaks down the key factors to consider, helping you make an informed decision for a quieter and more comfortable ride.
- Thickness and Mass: Thicker mats (80 mil and above) provide more mass, which is essential for damping vibrations and blocking low-frequency noise. Thinner mats (50 mil) are lighter and easier to handle but less effective. For van floors and large panels, choose 80 mil or thicker.
- Material Type: Butyl rubber mats are excellent for vibration damping and sound blocking. Closed-cell foam liners are better for heat insulation and absorbing high-frequency sounds. Many van owners use a combination: butyl on metal surfaces and foam on top for maximum comfort.
- Coverage Area: Consider the size of your van and the areas you want to treat. A 36 sqft roll covers about four doors or a small cargo area. For a full van conversion, you may need multiple rolls or larger kits. Measure your panels to estimate the required coverage.
- Adhesive Quality: A strong self-adhesive backing is crucial for a secure bond that lasts. Look for mats with high-tack adhesives that can withstand temperature fluctuations and vibrations. Some products include an installation indicator to ensure proper application.
- Heat Resistance: Vans can get very hot, especially near the engine or in sunny climates. Choose materials with high operating temperatures (up to 215°F) and reflective foil to block radiant heat. This improves comfort and protects the adhesive from degrading.
Conclusion
Sound deadening your van is a worthwhile investment that enhances comfort, reduces fatigue, and improves audio quality. Whether you choose a thick butyl mat like the KILMAT Extra or a foam liner like the VOISEN, the right product can make a significant difference.
For most van owners, a combination of a 80 mil butyl mat and a closed-cell foam liner offers the best results. Start with the areas that bother you most, and expand as needed. Your ears will thank you.
