Closed cell foam insulation performs so well for thermal retention that it is the only insulation we use at Cascadia Vans. Our closed cell foam comes in 1/8", 1/4" and 1/2" thicknesses. Sheets of all thicknesses are 40" x 80". This insulation is very easy to work with. Simply cut to fit with scissors or utility knife.
Empirical data has shown superior sound attenuation over other popular sound deadening products. CVCC Foam insulation is inert. It does not off-gas, no odor, it cannot mold or mildew and will not hold any moisture.
We use this product through out our custom builds to create a true luxury experience in your van.
