3M Thinsulate SM600L Insulation:
3M Thinsulate SM600L is a premium thermal insulation engineered for the unique demands of vehicles. At 60 inches wide and sold by the linear foot, this material is designed to expand to 1 3/4 inches or 44mm, providing more acoustic absorption per unit weight compared to competitive products. Its hydrophobic fibers resist moisture, mold, and mildew, ensuring a safe and healthy insulating layer. Thinsulate is also FMVSS 302 certified, meeting rigorous federal motor vehicle safety standards.
Tec Vanlife DUCK Liner:
Complement your insulation with our famous DUCK Liner, the ultimate barrier against both noise and condensation. The DUCK Liner works seamlessly with the Thinsulate insulation, enhancing its thermal properties and adding an extra layer of moisture resistance, ensuring your van remains dry and mold-free.
Bundle Benefits:
Easy Installation: Both products are designed for DIY installation, with Thinsulate utilizing Tensorgrip P307 or 3M 90 Adhesive Spray for a secure fit. The DUCK Liner is a peel-and-stick solution which adheres directly to the van walls, ceiling and floor.
Important: These are recommended starting quantities rather than exact cut lists. Actual requirements can vary depending on roof height, windows, interior layout and how extensively the doors and smaller cavities are insulated.
The current insulation bundle includes 2 boxes of Duck Liner. If the table recommends more than 2 boxes for your intended coverage, additional Duck Liner should be purchased separately.
Customizable Coverage: Tailor your insulation to your specific needs with our detailed Thinsulate Calculator & Installation Guide below, ensuring you get the exact amount of material required for your van model and size.
