SPRINTER 2019-2026 Pre-Cut 3M Thinsulate Insulation Kit

On the road, your van quickly becomes uncomfortable, getting hot under the sun, cold at night, and constantly filled with road noise. This pre-cut 3M Thinsulate insulation kit for the Sprinter 144” wheelbase solves all of these issues in one integrated system, providing thermal control, sound reduction, and moisture resistance. It turns your Sprinter into a quiet, temperature-stable, all-season living space without complicated installation.

3M Thinsulate uses ultra-fine fibers that trap air for insulation while absorbing vibration and sound. Unlike foam materials, it doesn’t hold water, making it resistant to moisture, mold, and long-term breakdown.

This kit is designed specifically for the Mercedes Sprinter 144” High Roof. Covers the cargo area, including walls, roof, doors and wheel wells, and does not include the cab, floor, or structural reinforcements.
