3M™ Thinsulate™ Van Insulation Kit — Mercedes-Benz Sprinter MWB-HI

3M™ Thinsulate™ Van Insulation Kit — Mercedes-Benz Sprinter MWB-HI (144" High Roof, 2007+)

Precision pre-cut acoustic and thermal insulation, laser-cut to the Sprinter's panel geometry for a true factory fit. No trimming, no waste, no guesswork — just labelled panels that match the included layout diagram and go straight onto walls, ceiling and doors.

Built around 3M™ Thinsulate™ SM600L, the kit delivers genuine year-round temperature control and serious road-noise reduction in a lightweight, moisture-resistant package that won't add meaningful payload to your build.

Why Thinsulate

• Quiet cabin — non-woven acoustic absorber engineered to soak up mid- to high-frequency noise, vibration and echo for a calmer interior.
• True thermal performance — R-value of roughly 5.45 per inch (RSI 0.96); cool through summer, warm through winter.
• Moisture & mould resistant — hydrophobic polypropylene/polyester fibres shed moisture and resist mildew. No separate vapour barrier required.
• Fast install — every panel is pre-cut and labelled to match the layout diagram.
• Lightweight — ~16.1 kg/m³ density adds minimal load, protecting fuel economy and handling.
• Safe to work with — no fibreglass, no off-gassing, no skin irritation. Meets FMVSS 302 fire safety.

What's included

• Pre-cut 3M™ Thinsulate™ SM600L panels for walls, ceiling and doors
