For walls and doors, we recommend flexible insulation that can fit into curves and around the structure of the van.
3M Thinsulate SM600L is an excellent pick because its cost-effective, water-resistant and conformable.
We often use our recycled jute products as well (EcoVerb Roll and Heat Wave Pro), which are extremey flexible, budget-consious, and eco-friendly.
Customers concerned about exposure to water often use Mega Zorbe - our line of hydrophobic melamine foam.
For ceilings, we will recommend these same products but will vary the thickness depending on the specific model and height of the van.
