Open Cell

At Bright Choice Spray Foam we offer open cell spray foam insulation as an option. It is a semi-rigid ½ pound per cubic foot and is low density. This water blown foam is designed to be used indoors only. Since the cells are open, it relies on trapping the air inside of the foam which then insulates the air seal. In the open cell spray foam the blowing agent is water. This helps the reaction process respond in the foam. In this insulation method there are no toxic gases used or released in the process. This type of spray foam works well in new construction, remodels, agricultural buildings and commercial settings. Remember that the open cell spray foam is not to be used outside. For outdoor purposes, see our Closed Cell spray foam.

When you spray the open cell foam into place it expands about 120 times itself and is a two part liquid. It cures into place within seconds. This method has the best cost per R-value of foam insulation. The R-value for most open cell foams are around 3.5 to 4.5 per inch. There are no ozone depletion chemicals such as; CFC, HCFC, fibers, VOC’s formaldehyde, or asbestos. The open cell spray foam is really good for an air seal and also for sound control. We prefer to use the Open Cell Spray Foam on above grade applications. It is Hydrophobic, so it is repels water well and it doesn’t wick up water. This is so because when it is applied to the underside of a leaking roof deck the water will drain down through it, so it will expose the leaking area under the deck. Both open cell and closed cell spray foam are excellent choices for insulation, but there are a few advantages to choosing open cell spray foam. These advantages include:

-Lower cost: Open cell spray foam is generally much less expensive than closed cell spray foam. -Better coverage: Because it expands more than closed cell, open cell spray foam is better able to completely fill a large area. -Safer blowing agent: Instead of using a chemical as a blowing agent, open cell spray foam uses water. -Versatility: Because it is less expansive and does not release any toxic gases in the spraying process, open cell spray foam can be used as insulation in a wide variety of situations.
