Check out the links and videos on this site: http://www.icynene.com/residential
I have limited experience in seeing this stuff in attics and walls, however, an easy way to identify closed cell vs. open cell is that open sell is soft and flexible while the closed cell is rigid.

Can you please tell me what is the advantage of foam spray in attic? Is it similar to waterproofing?

No it is not similar to waterproofing. It's insulation.

It's also a sealant. It reduces convection losses that result from air infiltration.

Go to spraypolyurethane.org. It's the SPF Industry Association.

It's also a man cave. I think a 50 incher can fit in there.

Closed-cell foam has tiny foam cells that are closed and packed together. These holes are filled with a gas that helps the foam rise and help in insulation.
In Open-cell foam the tiny cells are not closely packed.
You can make out difference by pressing them. Open cell foam has softer felling than closed foam.

Sarah, the difference between open and closed cell foam is a threshold. If 89% of the cells are closed it's considered open cell foam, 90% and it is closed cell foam.
The gas is hydrogen and oxygen, the most common blowing agent in SPF is water.
The feel of the foam is a density issue, measured as the weight of the foam in pounds per cubic foot. With foam manufactured in place (like spray foam insulation) it is more reliable to make dense foam with a closed structure and light foam with an open structure, but they are not mutually exclusive.

Yeah Bill, seems they've found a new way of link dropping.
Make several useless but non-issue posts.
Edit the signature block to include a link.
Bang! an automatic link in each of the useless crap posts they've done.
Good thing you mods have your eyes open!

Last night at about 1:30 am I locked out two different fellows that had come on here days, even weeks, registered and then left without posting. They came back, tried to post a couple of really stupid comments that made no sense whatsoever and then disappeared. At that point, I deleted their posts and locked their profile. I'm sure they'll be back but with your help we can prevent them from posting here.
