Elbi sprayed-on rigid insulation with acrylic topcoat exceeds ASHRAE 90.1 requirements with 2” of high-density polyurethane foam with an “R” value of R-16. SPF meets requirements for California Title 24. Elbi spray foam insulation has the best fire spread rating with a class I foam with less than a 25-flame spread rating suitable for boiler room applications.
The 100% acrylic topcoat is formulated for applications over spray polyurethane foam and is designed to withstand extreme weather and a full range of environmental conditions. The 2 component polyurethane foam is applied at ambient temperatures, directly to the vessel in the desired thickness. The 2-coat topcoat is then applied from a high-pressure spray gun and allowed to dry between applications. Metal jacketing is also available.
