Open Cell Vs Closed Cell

Light Density Open CellMore>

  • Spray in place insulation and air barrier
  • Vapor permeable.  There the material is allowed to breath
  • Will accommodate long term creep and seasonal movements
  • Does not sustain mold
  • Rejects bulk water
  • Drains water through
  • Typical R-Value of 3.6 per inch
  • Water commonly used for blowing agent
  • Suitable for interior applications only

Key Advantages of Open Cell

  • Soft, flexible and highly adhesive texture allows the product to retain a tight air seal during the normal structural movement/shifting over the life time of the building
  • Vapor permeable permits bi-directional drying of assemblies
  • When applied to the underside of a roof deck, will allow for bulk water to pass through and visibly expose the location of an exterior roof leak
  • Soft open cell structure allows for greater sound absorption versus closed cell structure
  • Using a water based blowing agent instead of a synthetic blowing agent reduces the environmental impact
  • Lower cost

This Video Does a Great Job of Showing the Characteristics of Open Cell Spray Foam Insulation.  The tell tale sign of Open Cell Insulation is that it expands very quickly.  There should also be about three times as much insulation on the substrate than Closed Cell Insulation.

 

 

Medium Density Closed Cell More>

  • Spray in place insulation and air barrier
  • Low vapor permeance
  • Vapor barrier (class II VDR)
  • Rigid design adds structural reinforcement
  • Does not sustain mold
  • Rejects bulk water (even submerged)
  • Deflects water path
  • Typical R-Value of 6.0 per inch
  • Blowing agent increases R value
  • Suitable for both interior and exterior applications

Key Advantages of Closed Cell

  • Higher R-value per inch, easier to accommodate higher R requirement in narrow spaces or thinner wall capacity
  • Hard, rigid texture provides increased wall racking strength (if necessary)
  • Also suitable for exterior and below grade applications as it rejects bulk water
  • Lower vapor permeance, can be a class II VDR
  • Impact resistance

    I am constructing a 40 x 60 shop space steel, with open ceilings 16 foot walls. What would the price be for that square footage and what R-value what I need to effectively have a radiant heat floor?

    How can I tell which type will work best for my needs?

      It all depends on what your application is. Generally in residential buildings we recommend using open cell foam. This is due to the fact that our open cell foam is 100% water blown. Our open cell foam provides our customers with a healthier alternative to closed cell foam. Also, open cell foam expands more than closed cell foam. This is good for homes that have more complex framing.
