Outside heat or cold can transfer from an exterior wall to an interior wall through six different methods of transference.  Spray foam insulation blocks all six and thereby helps to maintain a comfortable indoor temperature:


  •  Conduction
  • Convection
  • Radiation
  • Air Infiltration
  • Air Intrusion
  • Moisture Accumulation


 R-Value is NOT the answer alone!  R-value, the traditional measure of an insulation's effectiveness, measures only ONE of these six mechanisms.  Spray polyurethane foam effectively prevents or blocks all six heat transfer methods.








Spray Foam Eliminates Air Leaks!

Air leakage can contribute to problems with moisture, noise, dust, pollutants, insects, and rodents.
Small voids of 1-2% at the end of fiberglass batt insulation can result in a 25-40% reduction of R-value due to air leakage. Air leakage can account for 30% of a home's annual heating and cooling costs. Spray polyurethane foam seals the building envelope to create an optimal energy-efficient environment.









Spray Foam Maintains indoor air quality by virtually eliminating mold and fungus!

The Building Science Corporation believes that insulation products capable of achieving green building standards need to control moisture, air movement and temperature in one material.  SPF is the ONLY product in the industry that can control all three.



  •  Spray polyurethane foam contributes to healthy buildings by reducing air leakage thereby preventing condensation within the envelope.
  •  Mold and mildew growth cannot occur in the absence of water.  Spray foam prevents water vapor transported by air leakage from entering the building envelope thereby helping prevent mold growth.
  •  Thermal bridging is a significant cause of energy loss.  With no fasteners, joints or gaps, spray foam eliminates thermal bridging.
  •  Spray polyurethane foam improves indoor air quality by reducing the transport of dust and pollen from outside.
  •  Spray polyurethane foam reduces drafts and air movement.







Excellent Sound Dampening Properties


  • Closed-cell foam blocks transmission of low frequency sound.
  • Open-cell spray foam absorbs mid to high frequency sound
  • Air-tight, void-free walls minimize sound pathways.
