Why Buy 3M Thinsulate by the Foot
3M Thinsulate SM600L is a high-performance thermo-acoustic insulation. It's engineered to tackle unwanted road noise and thermal transfer, and this heavy-duty, premium-grade material is a go-to choice for professional van builders, automotive restorers and DIY camper conversions. Buying it by the foot means you pay for what your van needs, not a full roll.
Key Features & Benefits
- Acoustic attenuation: as the thickest and most absorbent option in the SM series, SM600L uses a dense matrix of microfibers to absorb high- and mid-frequency road, engine and environmental noise.
- Thermal control: delivers strong R-value performance, keeping your cabin warmer on freezing winter nights and cooler under summer heat.
- Moisture & mold resistant: built with hydrophobic polypropylene fibers that do not absorb water, reducing the risk of condensation buildup, mold, mildew and musty odors.
- Lightweight & compressible: maximizes energy efficiency and payload capacity without adding dead weight. It easily conforms to complex, irregular surfaces, ribs and cavities.
- Protected with durable scrim: a single-sided black polyolefin (non-woven) protective scrim enhances durability and makes handling and installation cleaner and easier.
- Safety compliant: certified self-extinguishing and compliant with FMVSS 302 (SAE J369) automotive fire safety standards.

How Much Do You Need?
If you're buying 3M Thinsulate by the foot for a whole van, plan on 45-50 ft. For door panels or topping off a kit, order just the feet you're short. With a 60 inch roll width, each foot gives you 5 square feet of SM600L insulation. Let it expand fully after unrolling before you fit it into the walls.
Where Insulation Fits in Your Build
With 3M Thinsulate by the foot, insulation goes in after your furring and before your wall and ceiling panels. Pair 3M Thinsulate by the foot with van furring kits and van wall and ceiling kits, or insulate the floor with Ford Transit floor insulation. Learn more from 3M.
