What is the difference between High Density and Closed Cell foam? is one more compressible than the other?
1612778
There is closed cell foam and open cell foam. Think of it like the difference between a box of balls and a box of crumpled paper. The density of the foam depends on the size of the cells, the thickness of the walls of the cells and the type of material used to make the foam. Open cell foam will hold water, closed cell foam will not. Hope this helps.

I didn't check the actual density but it feels pretty dense to me, three inches of high quality memory foam, can't go wrong!

Memory foam density is measured from 3.0 to 5.0 or higher. Does anyone know how to answer the question?

Yes, I would use the closed cell for masonry it provides benefits of sealing from moisture penetration. Also there is an open cell that works for sound deadening.

The high density foam they sent me is conventional foam. Most typical bedding companies will use low density conventional foams in their products which will have a higher propensity to break down over time. Typically lower density means lower cost and lower quality. Memory Foam is foam which is slow to recover like the Tempurpedic material. I had a Tempurpedic and I was constantly sweating as the mattresse did not breathe. Hated it. Conventional foam will recover right away and not leave an impression behind and will be much more breathable. Hope this helps.

The separate piece of foam inside the cover is 1" to 1.25" thick, as-stated by several others. I will add that it's medium-density, at best, and thus compresses very quickly and doesn't provide that much support. Better than nothing? Yes. Could it be better with thicker or higher-density foam? Definitely! I have a garden kneeling pad that's approximately the same thickness, but much more dense and rubber-like. If I were to cut a piece out of that and put it inside the cover, I'm sure it would be much more comfortable!

A typical foam will return to its original shape after being released from compression. On the other hand, memory foam will return to its shape slowly, making it look like the foam has "memory" to the compression. Thus nicknamed "memory foam".

Yes, I called Amazon because of the confusion with the pictures. This item is a full round and it is very dense. I had to work my way up to this density because there is no give in the foam. I did order the half round for lower back stretches.

According to the www.certipur.us web site, the foam is made without standard (PBDE) flame retardants. One other advantage is that the foam is low volatility, which means chemical vapors from the manufacturing process are lower than average.

Yes, I have the shikibuton trifold and it is a high density foam, not memory foam so it is much firmer. I think that is the main difference. The other differences you can observe for yourself

Hi Chris, Thanks for your interest in Foam It Green! Open cell foam will stop most of the air flow, but not moisture penetration. It expands about six times what you spray (spray 1/3rd-inch layer, which will rise out to approximately 2" in depth), and provides an insulation value of R-3.6 per inch. Closed cell foam stops both air and moisture penetration, and is much more dense than open cell foam. Unlike open cell, closed cell foam will not hold moisture and can prevent condensation from forming within your insulation. Closed cell foam will expand about three times what you spray (spray 1/3rd-inch layer, which will rise to approximately 1" in depth), and it provides an insulation value of R-7 per inch. I'd be happy to answer any additional questions you have about using Foam It Green for your project. Just give me a call at 800-516-0949. Thanks! Linda

I've never actually owned a foam mattress before, so it's hard for me to say, but I would assume it's more like a classic type foam. Sorry I can't be more helpful, maybe someone else can shed more light on it.

It has three different layers of foam. I don't remember if it even had the density but it is a wonderfully firm and comfortable mattress.We use it in our RV. I have the double and my sister has the king and she likes hers equally well.

The main difference is the product has an offset inside diameter which allows easy installation, with thicker padding toward driver or side where protection is needed. It is also denser than most closed cell pipe insulation and not as flexible so it absorbs more impact energy.

Could you be more specific I don't understand the two colors of foam portion of your question.

Hi Michael. The foam is vacuum to the smallest in size it can became to minimize shipping costs. We use a vacuum to pull the air out. We welcome your business.

This foam is the "closed-cell" type. Based on my research, closed-cell is preferred over open-cell for below-grade insulation or on floor-joists in a basement or crawlspace because it is much denser than open-cell and is a very good air barrier as well as a water vapor barrier.
