FREQUENTLY ASKED QUESTIONS

What is the difference between open celled and closed celled foam insulation?
It means the open cell is open. It also give about 30%  structural strength to the building. At 3 inches thick it give you a thermal break,  air barrier and a R value.  With the open cell it will expand 120% mass of value. It will fill in hole and grabs where you can’t get .
 
Close cell is the cell structure is closed.  Close cell will give you around 80 % structural strength to building. After 1 inch you got a thermal break , air barrier,moisture barrier and  a R value.  It has a higher R value than open cell per inch . In tight areas close cell don’t do as good as open cell.
 
Understanding the quality of the foam open or close cell. High the poundage of the foam.  Means higher the R value better performance.
 
Close cell spray foam is a vapor permeable.  It’s able to accommodate seasonal shifting and not food source for mold. It’s ability to deflect water and pervide a vapor barrier,  close cell foam will work on both  exterior and interior. It’s mostly use for matel building and fondation. Do to the vapor barrier, air barrier and a R value per inch.
 
Open cell is a air barrier and a R value.  This is porous so water can pass though.  If your roof was leaking you would be able to find it. Foam will dry out and not a food source for mold.  It fill in gaps and hole better. It last as long as the house .
 Why go with foam it’s got an air barrier & R value it  . It’s stay in place and don’t slide down the wall or compress by gravity or loss R value over time. It don’t deteriorate or break down like other insulation. It don’t loss heat or air do to the slow permeation.

What can go wrong with a bad foam job. Spraying over it multiple time back to back with out letting the foam cured out. Gas gets trap between the lays and sometimes it don’t leave. Cell structure don’t develop right and become long gated. And close cell could char and could ignite.  Also you could get pocket, fractures , pulls or long gated cell structure. Cold foam not good or not getting  a good acclimation of two part I.S.O or resin .Lot got to do with the quality of foam and the sprayer

Can Icynene be sprayed over existing insulation, such as fiberglass or cellulose, or would the previous insulation need to be removed first?

The previous insulation does have to be removed before the Icynene is applied. Foam Pro offers an additional service to remove the previous insulation.

Do you do spray insulation in existing homes?

Yes, we insulate existing homes every week. Attics and crawlspaces are the most popular because they are non-invasive. We can do existing walls as well.

Does the insulation support bacteria or fungal growth?

Icynene insulation offers no food value; therefore it does not support bacteria or fungal growth. It also does not retain water, making it an unappealing environment for pests. Independent testing by Texas Tech University confirms that Icynene will not support the growth of mold

Is the insulation corrosive to metals?

No, Icynene insulation is non-corrosive. It is neutral, neither acidic or alkaline.

Are homes being built too tight? Are we actually creating a greater indoor air quality problem by sealing the building envelope completely with Icynene spray foam insulation?

With the proper use of exhaust fans and heat/energy recovery ventilators, a building envelope can be made tight while clean, healthy air is circulated through the structure. Air leakage needs to be controlled in houses by making wall and attic assemblies as tight as possible. This not only prevents drafts, but reduces the amount of airborne noise and dust from entering the building while ensuring that insulated cavities do not become full of condensation.

What is Icynene insulation made of?

Icynene insulation is a water-basted formula that contains no formaldehyde, CFCs or HCFCs. The foam insulation is made up of millions of tiny cells. These cells are filled with air and provide permanent control of air and airborne moisture movement.

Is the insulation flammable?

Icynene insulation contributes no fuel in the event of fire and it will not sustain flame upon removal of the flame source. However, like fiberglass, it will be consumed by flame.
