Not really. I would leave them in for insulation value if its convenient. Otherwise ditch them.

I am going to use "pour foam" urethane on my floor and walls.

PROS: R6 per inch, every nook and cranny filled, sound reducing, so strong, it will be my floor, easy to install

CONS: Expensive, $520 for 2 inches of floor insulation, messy

Note the foam blocks are quite important per the BEG

Too late for me, I threw the foam blocks away. Did not realize I left them out until after the headliner was reinstalled. Not sure they would have worked anyway with all the modifications.

Thanks! Looked it up.

This Standard applies to MPVs, trucks and buses with a GVWR or 10,000 lbs. (4,536 kg) or less. It establishes requirements for the use of energy-absorbing materials on the interior components such as instrument panels, seat backs, interior doors, armrests and sun visors.

Beginning Sept. 1, 2007, trucks, buses and MPVs produced in two or more stages with a GVWR of 10,000 lbs. (4,536 kg) or less must provide head protection when an occupant’s head strikes upper interior components, including pillars, side rails, headers and the roof.

This is the first thread that I've seen Thinsulate mentioned for use in the floor. Is there a thread around that details the assembly of the layers for a floor using Thinsulate ? Are there furring strips involved to prevent the Thinsulate from compressing or is there a more dense variety of Thinsulate as there is with Rockwool ? What am I not understanding ?

Why hasn't Rockwool (Roxul) become more prevalent in insulating vans ?

If your head reaches the location of the foam blocks then you have some other major issues to deal with.

Minicell is our most popular floor insulation. We are also using Thinsulate AU4002-5 double scrim under plywood floors. Strategic use of furring strips or blocks may be required although I have had customers with Sprinters just roll out the Thinsulate and then lay their floor over it. It does compress a bit but will not loose all of it's loft.

All the best,

Hein,

In a post somewhere you mentioned you would have 3M sound deadener / absorber available in the fall. I'm at the point where I need to apply sound absorbing mat if I am going to use it. Is the 3M product available yet? Do you have a spec sheet for it?

We have put in our order request but do not yet have a delivery date. Pricing is to be determined. We will stock both 1.6mm and 2.9mm thicknesses.
