Spray-on Insulation with Topcoat

Spray-on Rigid Polyurethane Foam with Acrylic Topcoat

Niles Steel Tanks sprayed-on rigid insulation with acrylic topcoat exceeds ASHREE 90.1b requirements with 2.25” of high density polyurethane foam with an R value or R-16. The spray-on foam meets requirements in California Title 24. Niles spray-on foam insulation has the best re spread rating with a class 1 foam with less than a 25-ame spread rating suitable for boiler room applications. The 100% acrylic topcoat is formulated for outdoor applications 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 and rises to the desired thickness. The acrylic topcoat is applied from a high pressure gun once the foam has set. The acrylic topcoat is UV reective which protects the spray-on from deterioration from the sun.
