Why Thinsulate

• Quiet: absorbs road noise, drone and echo, strongest in the mid to high frequencies.
• Comfortable: helps keep heat out in summer and warmth in during winter.
• Won't hold water: hydrophobic fibres resist moisture, mould and mildew. No separate vapour barrier needed.
• Light and clean to fit: cuts with scissors. No fibreglass, no itch, odourless.
• Fire safe: self-extinguishing, meets FMVSS 302 for automotive interiors.

Specifications

Fitting

1. Open the bag and unfold the piece. It takes 72 hours to a week to fully re-loft. It's easier to fit while still compressed.
2. Cut to shape with scissors or a sharp knife.
3. Spray adhesive on both the panel and the insulation, wait until tacky, then press in place.
4. Fill cavities and pillars loosely. Don't crush it.

Spray adhesive

Use a high-temperature, heavy-duty spray adhesive. Van panels get hot in an Australian summer, and general-purpose craft sprays let go.

• Recommended: 3M™ Hi-Strength 90, 500 g. Allow 4 cans for this van. Add it to your order at A$52.90 a can. Aerosols ship by road within Australia, separately from your insulation.
• Pick up locally: Selleys Kwik Grip High Temp Spray, 350 g, rated to 90 °C, from Bunnings or Mitre 10. Smaller can, so allow about 6 cans.
