Open cell is spray applied polyurethane foam that expands 120 x its liquid volume providing superior insulating, air sealing, and sound properties. Open cell foam utilizes water as a blowing agent trapping air in the structure of the cells. Open Cell SPF has an R-value around 3.5 per inch and typically uses water as the blowing agent.

Open cell foam like works on all three principles of heat transfer. This is what makes foams superior insulators. As well as a great thermal insulator open cell will provide for excellent sound reduction. Open Cell SPF cells are not completely closed and air fills all of the ‘open’ space inside the material.

Benefits

  • Real world R-value performance
  • Completely fills tight spots and hidden areas allowing for performance gains that would otherwise be overlooked by other products.
  • Great sound reduction properties
