The Icynene Insulation SystemŽ
We built a new house and used this system. So far it is performing very well.

It's a spray on or in expanding foam. I had to do a search also.

The Icynene Insulation SystemŽ
The R value is very high & it only expands to 3.5 inches. I am right in the middle of negotiating having my attic done. My house is a 100 years old & it was insulated with R 11 in the ceiling of the 2nd floor when insultation was first invented. When I bought the house I gutted it & reinsulated the walls with new batts. I was going to do batts in the attic this winter. I was on a job were they were spraying a house with the icynene so I asked the applicator about it. He said they do many old houses & instead of removing the existing batts in the attic floor, they just spay the attic ceiling & gable ends & the house will have no leaks at all. They are scheduled to do it the middle of January. He said it has an R 39 rating.

I built my new house 6 years ago to be very efficient. I used 2x6 walls and had them foamed with Icynene. I still marvel at how tight this house is. Besides being very high on R value, its biggest benefit is the ability to seal air tight every nook and cranny. Behind every wiring box, window sill, pipe, etc. It is tight. My power bills average $37 year round, and I'm all electric.
If I ever built another house, this is one thing I would insist on. Well worth the money.

The Icynene Insulation SystemŽ
There seems to be some confusion about these insulation systems. Icynene is a brand name. It is an open celled foam. Open celled foams have an R value of 3.6 per inch. There are also closed cell foams being used. These have an R value of 7 per inch. The way you tell the difference between the two is open celled foam is soft like a pillow and closed cell foam is hard. Fiberglass insulation has a claimed R value of 3.7 per inch. Foams claim to fame is that it expands into every nook and cranny of the building and virtually stops all air infiltration. Closed cell foams are usually much more expensive than open celled foams. Foam expands greatly upon application (100:1). The R value is determined by the amount of material the installer places in the cavity. Typically an Icynene insulation quote will be 3" in the walls and 5" in the ceiling. To achieve a R-39 value in a ceiling approximately 11" of foam would have to be sprayed. I think that if you question the installer he would be more than likely spraying 5-6" of foam and claiming it performs better than R-39 of fiberglass.

is there a risk of water getting in the open cell if there is ever a leak somewhere? is there any risk of rotting the wood under the shingles? and what about too much heat in the summer? In the winter isn't the heat going to escape your living area and then get insulated in the attic? I am asking because I am building a house next year and really like the foam idea.

If there is a leak the foam will not absorb water. Your sheathing will not rot because there is there is no water vapor or air infiltration that gets past the foam. You also will not need house wrap. What causes roof shingles to fail is when there is a wide temperature differential between the outside and inside of the shingle. The foam prevents this. We foamed all the interior bathroom walls and any walls that have plumbing drains. This greatly aided in keeping these areas isolated noisewise from the rest of the house.
