To Winterize a cabin or not...

Secondary because natural gas has lots of moisture. I don't have condensation problems because the gas forced air furnace without a humidifier is the primary. As my other post said, the (big) pilot adds the much needed humidity and decreased my monthy gas bill at least $20.

jpsted,
The product is a closed cell foam, (not open cell) thickness is around 2" to 3".
It is sprayed at hi pressure around 1200 psi and starts as a liquid, so it gets into all the cracks and holes than it expands.
I had it come out of some of my cracks on the outside of the blocks.
Seals everything up with no air movement or drafts.
Most insulating companies are doing it now.
As for pictures I am 350 miles from my cabin now but go online and search for crawl space insulation or closed foam and you will fine it.
It reminds me of the spray foam that is used in boxes to keep things from moving, kind of a white tan color.

Thanks Trick/Track!

Caution

We have a place in Oneida County and used to winterize after each weekend. Problem came about when we did not visit for over a month, extreme cold hit (-25) for an extended period. We ended up with frost under the basement slab and even down to the foundation footing. The slab and foundation wall heaved and broke seals on windows, cracked the slab and we had a patio door bind in the opening. Never again will we make the mistake of winterizing during extreme cold. Shut down pump and open faucets. With electric heat we also use a set back thermostat programmed to heat extra during off peak periods ($0.01/kwh) and go back to 45 degrees during on peak ($0.08/kwh).
