Product Information

🔇 Two layers for a quiet van

DUCK Liner goes on the bare metal first to reduce vibration and road noise. Thinsulate goes over it for thermal and acoustic insulation in the walls, ceiling, doors and cab area.

💧 Stops condensation

DUCK Liner separates the interior from cold metal surfaces to prevent condensation. Thinsulate is hydrophobic and helps prevent mould and mildew.

☀️ Reflective foil layer

The foil layer on DUCK Liner reflects radiant heat away from the van walls to keep the inside temperature stable.

🔥 Made for vehicles

Thinsulate is FMVSS 302 certified for flammability. DUCK Liner is non-combustible and resists corrosion.

✂️ Easy to install

DUCK Liner has an adhesive backing: cut, peel and stick. Thinsulate is light, easy to cut and fits around ribs and curves.

📦 Save with the kit

The Van Insulation Kit includes 2 rolls of DUCK Liner and 3M Thinsulate SM600L for a complete, all-in-one solution.
