OPEN CELL VS CLOSED CELL

OPEN CELL VS CLOSED CELL


Light Density Open Cell – More>

  • 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 lifetime 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

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
