SPF Insulation Uses Hybrid-Cell Approach
Hybrid cell technology allows a new spray polyurethane foam insulation from Rhino Linings (San Diego) to bridge the gap between the company's open- and closed-cell products, according to the manufacturer.
ThermalGuard OC1.6, which can be used in both architectural and industrial settings, is a fast-set, water-blown SPF that expands to 25 times its size in a matter of seconds, the manufacturer says. It has a nominal density of 1.6 pounds per cubic foot at 2 inches, and an R-value of 5.9 per inch.
The SPF is a two-component spray consisting of a resin and an isocyanate component; it contains no VOCs, ozone-depleting substances or HFCs, and is PBDE-free as well, according to Rhino Linings.
Structural Strength, Fewer Challenges
Like a closed-cell SPF, ThermalGuard OC1.6 maintains structural strength once it sets, and is recommended by the manufacturer for residential and commercial structures as well as exterior or foundation insulation, below-grade applications and tank exteriors.
"Our new hybrid product, ThermalGuard OC1.6, boasts the semi-rigid appearance and compressive strength of a standard 245fa-blown 2-pound closed cell spray foam without the closed-cell product challenges like off-gassing in the drum or the inability to recirculate and pre-heat material when conditions warrant," said Pierre Gagnon, Rhino Linings’ president and CEO.
The new product bridges the gap between Rhino Linings’ open-cell, lower-density sprays and its closed-cell, more rigid products, the company notes. It can replace a 2.0-pound density spray, the company says, in applications where a lower-cost, semi-rigid foam is desired.
The product comes in twin 55-gallon drums.
