Default Thinsulate

I know Hein (Impact Products) has been the main supplier of Thinsulate for van conversions. What he sells has black scrim on one side. I noticed Adventure Wagon sells Thinsulate (same thickness, 44mm) with scrim on both sides. Any thoughts on which is better?

Also, Hein recommends 60sq ft for a 170 and Adventure Wagon says 75sq ft. Which is the right number for a 170 Crew and I'm planning on flares with windows both sides, XPS foam u der the floor.

Thanks,
Josh

Hi Josh, I work for Adventure Wagon. The choices are very similar. We use the dual scrim primarily for the ability to double stack the thinsulate for lower compartments in the van. This was based on the recommendation from the 3M guys. The dual scrim simply gives us a cleaner surface area for bonding. We also use 3M double stick tape and simply put a couple of small pieces between the two layers then again a few pieces to adhere it to the wall of the van.

This also may be why we advocate using more thinsulate in your 170. For our interior kits we trace out every compartment onto the 3M like a jigsaw puzzle and double stack the lower areas and include the cockpit headliner. Our number reflects what we are using in our kits.

The Adventure wagon kits are for those folks who can't use scissors. The double scrim is much harder to cut and doesn't connect as well to the sheetmetal for resonance control. There is no need to double up as the air space is the walls provides additional R-value and provides some room for air to circulate and allow moisture to escape.

We have been supplying 3M Thinsulate(TM) for many years and are the preferred supplier for 3M. Our prices are lower and our service is better than anyone else.We do stock double scrim and thinner versions of Thinsulate(TM) and have the expertise to help you decide which product and insulation strategy best suits your needs. We also stock Low-E which can help improve the R-value in the roof where the depth is less and heat load higher.

Josh, please call today and we can go over your questions. We recommend 60 linear feet (300 sq ft) for a typical 170 Sprinter.

All the best,
Hein

Yes, 60 linear feet sounds more accurate. 60 ft2 would not cover the ceiling on my 170. I just took delivery of my last roll of Thinsulate for a total of 65 linear ft and filled every accessible void in my van. Thinsulate is worth the expense based on all the factors associated with installing insulation. I have multiple sheets of poly iso that I will give away. The poly iso although inexpensive is a pain and a mess to install. I also learned that if the poly iso rubs against anything you will have annoying squeaks. Spray foam insulation can lead to problems documented on this forum but the bigger issue is running electrical and plumbing through a van with foam. Very happy with the Thinsulate.

I've seen people install insulate with the scrim side on the sheet metal which I was told allows the white stuff to loft. What is your take on this?


Thanks,

Jim

We install Thinsulate(TM) with the fiber side to the sheetmetal to help wick condensation away from the surface should it occur there. We are taking advantage of the characteristic that makes Thinsulate great in garments. Thinsulate fibers expand and conform to the surfaces. The improved contact will allow the Thinsulate to control panel resonance and eliminate the need for mass loading products like dynamat, fatmat, etc. Installing with the scrim on the outside isn't wrong but there is no need for scrim on both sides. Thinsulate has been used in the marine industry for a long time. It's always installed with scrim out. The scrim is designed as protective layer. No reason to put that in a place where protection is not needed.

We don't see any reduction of loft over time and the weight of the scrim has actually increased it inside the roof of our Transit. We haven't installed a headliner so have been rolling with the Thinsulate(TM) scrim as our headliner for ~7000 miles. The roof beams of the Transit are 1.75" deep and the Thinsulate has lofted to in excess of 2" between where the scrim is attached to the roof beams. The fiber side is still firmly attached to the sheetmetal.
