The Heatlok HFO closed-cell spray foam series leverages Honeywell Solstice liquid blowing agents. Designed on the molecular level to specifically address the challenges of today’s building envelope, the spray foam is certified by the Air Barrier Association of America for adhesion to most air barrier materials and achieves an R-11 to exceed ASHRAE 90.1 continuous insulation requirements at 1.5 inches. In addition, the product provides a vapor retarder (less than 1 perm) at 1-inch thickness, a full 35 percent thinner than current Demilec materials, providing moisture vapor control within the exterior cavity.
