Open cell foam is usually more suitable for residential applications for several reasons. Open cell foam is more flexible than closed cell foam. When the framing members expand and contract with the weather, open cell foam will flex with the wood. Another difference between open and closed cell foam is that, if a leak develops, the closed cell foam will not allow the water to weep through the foam because it is a vapor barrier. This can lead to rotting before the leak is ever discovered. Open cell foam is not a vapor barrier, so it allows the water from the leak to weep through the foam to the space below. After the leak is repaired, the open cell foam can be allowed to dry and its thermal properties return, unlike other forms of insulation which must be replaced when they get wet. In addition to these differences between open and closed cell foam, open cell foam is usually less expensive than closed cell foam.
The previous insulation does have to be removed before the Icynene is applied. Epiphany Foam Insulation offers an additional service to remove the previous insulation.
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.
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.
No, Icynene insulation is non-corrosive. It is neutral, neither acidic or alkaline.
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.
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.
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.
