DS Thermal Pro 5mm Sound Deadening & Insulation

Create a quieter, more comfortable vehicle with DS Thermal Pro 5mm. This self-adhesive two-in-one product combines premium butyl sound deadening with a reinforced aluminium-faced thermal layer, helping reduce vibration, panel resonance, road noise and heat transfer in one straightforward installation.

It is ideal for campervans, motorhomes, cars, vans, 4x4s, horseboxes and commercial vehicle conversions, and can be installed beneath carpet lining, plywood panels and interior trim.

Why Choose DS Thermal Pro 5mm?

• Combines sound deadening and thermal insulation in one product
• Premium butyl layer helps reduce vibration and panel resonance
• Reinforced aluminium-facing helps reflect radiant heat
• 5mm overall thickness
• Self-adhesive backing for easier installation
• Flexible construction for curved and shaped panels
• Moisture-resistant finish for interior vehicle use
• Suitable for professional converters and DIY van builds

Where Can It Be Installed?

Apply directly to clean, dry painted metal in areas such as:

• Roofs and side panels
• Doors and tailgates
• Wheel arches and rear quarters
• Floors and bulkheads
• Campervan and commercial vehicle interiors

How It Works

The butyl base bonds to the vehicle panel to help control vibration and resonance. The aluminium-faced upper layer adds thermal performance, helping reduce heat transfer and improve comfort throughout the year.

For deeper cavity insulation, pair it with DeadSound Thermal Fleece. For a finished interior, cover it with DeadSound 4-Way Stretch Carpet Lining.

Installation Guide

1. Clean and degrease the metal surface thoroughly.
2. Measure and cut the material to the required shape.
3. Remove the backing film.
4. Apply the material firmly to the panel.
5. Use an installation roller to remove trapped air and ensure full contact.
6. Seal adjoining sections neatly where required.

For neat seams, use Thermal Sound Deadening Joint Tape.
