3M™ Thinsulate™ Insulation + Sound Deadening Pack — Mercedes-Benz Sprinter MWB-HI

3M™ Thinsulate™ + Sound Deadening Pack — Sprinter MWB-HI (144" High Roof)

The complete, do-it-once quiet-and-comfortable system for the 144" High Roof Sprinter — premium 3M™ Thinsulate™ SM600L thermal-acoustic insulation plus Stage 1 butyl sound deadening, matched and bundled to save.

What's in the pack

• Stage 1 — Sound deadening: high-mass self-adhesive butyl sheets to kill drumming and road roar on bare panels.
• Stage 2 — 3M™ Thinsulate™ insulation: pre-cut, labelled SM600L panels (44 mm, R≈5.45/in) for walls, ceiling and doors — true year-round temperature control and best-in-class acoustic absorption.

Why this beats a foam-only kit

Most Australian van packs use thin closed-cell foam. This pack leads with genuine 3M™ Thinsulate™ — thicker loft, higher R-value, superior mid–high frequency absorption, hydrophobic so no condensation trap and no separate vapour barrier.
