Open Cell Vs Closed Cell Foam Differencesw








Closed-Cell Spray Foam:


Closed-cell spray foam (likewise called 2-pound foam) has a density of about 2 pounds per cubic foot and an R-value of 6 to 6.5 per inch. Due to the fact that it is a denser material, closed-cell spray foam not only offers a vapor and water barrier to a home or structure, however also includes additional structural strength. Closed-cell spray foam normally costs more than open-cell spray foam.

Because the cells in closed foam spray have their own structure and don't share any structure with other cells, the foam has a greater plastic material and less air. The industry standard for spray foam to qualify as "closed cell" is that greater than 90% of the cells are closed.

Advantages of Closed Cell Spray Foam
While open-cell and closed-cell foams are both polyurethane-based, the primary difference between the two is that closed-cell foam is:

Denser

  • 2 and a half inches of closed-cell foam have a permeance of 0.8 perm. Less water/air can pass through a closed-cell foam
  • Much heavier
  • Because closed cell foam is denser, it provides added wall/structural strength. One place that open cell would be a better fit could be an attic or ceiling, due to weight.
  • Provides much better insulation and water barrier
  • Although it is generally more material (and therefore more pricey) than an open cell spray foam, closed cell foam is less permeable and more water resistant. This can prevent undesirable mold/moisture in surprise places.


Rate Factor to consider
Although there are many benefits of having a closed spray foam insulation, the price is a downside simply due to the fact that there are more materials needed to produce the denser insulation. Closed cell foam is more costly per "R," * so one can expect an R-10 of closed cell to be costlier than R-10 of open cell. There is more plastic utilized in closed cell, and the chemicals utilized for a blowing agent in closed cell foam is much more expensive than the water used in open cell foam. Nevertheless, there are benefits of increased effectiveness and strength. The professionals at Ozark Foam Insealators more than happy to review advantages with your needs.






Open-Cell Spray Foam Insulation:


Open-cell foam is a reasonably vapor-permeable compared to closed cell spray foam. It weighs 1/2 pound per cubic foot, with an R-value of 3.5 or 3.6 per inch. Open-cell foam is created for indoor usage just, and it's semi-permeable type traps air inside the foam, and in turn insulates the air seal. Open-cell foams utilize co2 or water as the blowing representative.
When the open cell foam is sprayed, it broadens about 120 times it's liquid volume and treatments in place in simple seconds.

Benefits of Open Cell Spray Foam
Although open and closed cell spray foam are both fantastic ways to insulate, there are some factors that people choose open-cell foam instead of closed:

More Cost-effective: 
Open-cell spray foam is generally a lot more economical than closed-cell.
Much Better Growth in Cracks: Open cell expands more readily than the much heavier closed cell spray foam, and is much better able to entirely fill an area.
Water as a blowing agent: Instead of utilizing a chemical, open-cell spray foam utilizes water as a blowing agent to spray the foam. There are no chemicals like CFC, fibers, VOC's formaldehyde, or asbestos.
Finest Cost per R-value: The R-value for the majority of open-cell foams are around 3.5 to 4.5 per inch.
Versatility: Because it is less extensive and does not release poisonous gases, open-cell spray foam is used as a flexible insulator.
Energy Performance: Open cell spray foam will keep your heating & cooling costs down by producing a tight air seal.
Applications for Open Cell Spray Foam
Open-cell spray foam can be used to insulate different locations of a building or house, including the:

attic
spray foam in specifically helpful here, since it is applied to the flooring or the underside of the roof
ceiling
Open-cell spray foam is lightweight, which is perfect for a ceiling
walls
produces an airtight seal, keeping your conditioned or heated air in, and undesirable air out
basement
likewise develops an airtight seal here, however, it is essential to make sure the basement is water evidence, due to the fact that open-cell spray foam is less waterproof than closed-cell.
