Spray Foam Insulation & Silicone Roof System

The Last Roof Your Residential or Commercial Structure Will Ever Need.

Spray Applied Polyurethane Foam (SPF) offers 2 big benefits to Honolulu, Oahu, Hawaii.

  1. Spray foam insulation offers a superior seal to your roof. Seamless and fully adhered, Spray foam insulation seals all transitions and penetrations on a roof.
  2. As an air barrier, spray foam insulation has the highest R-value of all insulation materials, lowering energy cost, ensuring faster payback of installation expense. Depending on the pounds per cubic foot and density of the foam determines the relative insulating values.
2 Lbs. Density Interior/Exterior Air Barrier Spray Foam (Closed Cell)
  • 1-½” = R10
  • 2” = R13
  • 3” = R20
  • 4” = R26
  • 5” = R33
0.5 Lbs. Density Interior Sound and Air Barrier Spray Foam (Open Cell)
  • 1” = R4
  • 2” = R8
  • 3” = R12

Spraying foam in your attic is one of three ways to meet the new Hawaii building codes that require new construction to achieve energy efficiency by meeting two of these three requirements; reflective roofing material, proper ventilation or insulation.

Installing interior spray foam insulation is easier to do during the initial construction phase when the walls are open and exposed and the underside of the roof sheathing can be easily accessed. Retrofitting spray foam insulation to an existing structure can be messy and costly, as all the drywall needs to be removed from the walls that will be receiving the spray foam insulation.
