Foam Insulation

         Huntsman Building Solutions, a global provider of high-performance, sustainable building envelope solutions, has announced that its HEATLOK® HFO Pro Closed Cell Spray Polyurethane Foam insulation has successfully completed NFPA 285 fire testing for metal and aluminum wall assemblies.  HEATLOK HFO Pro spray foam acts as a combined air barrier, vapor retarder, water barrier, and thermal insulator in one.  Already a standout insulation system that optimizes the building envelope, it now boasts this key fire safety certification, which will undoubtedly advance its marketability even further among builders, architects, contractors, and building owners.

         The NFPA 285 testing provides a method for determining the combustibility characteristics of exterior non-load bearing wall assemblies.  The testing is intended to evaluate the combustible components within the wall and simulates a multi-story fire performance for an entire wall assembly.  Testing of the HEATLOK HFO Pro applied with metal wall panels was conducted by Intertek Labs in York, Pennsylvania, and testing for the spray foam applied with aluminum wall panels was completed by NTA, Inc. in Bryan, Texas. 

         In both labs and with both sets of wall panels, the spray foam was tested and passed all scenarios.  The metal panel, in particular, was tested at a 2” and 3”-applied thickness, passing without a thermal barrier coating on top of the foam.  This is a result that many manufacturers have tried to achieve without succeeding.  Without the need for an additional thermal barrier coating behind metal panels, HEATLOK HFO Pro reduces the cost of the wall assembly compared to other brands of SPF and saves one step on construction sites.  Prior to this most recent testing, HEATLOK HFO Pro had already passed NFPA 285 testing for use with brick, stone, and masonry exteriors. 

         HEATLOK HFO Pro may now be installed with various types of commonly installed cladding on many different types of construction without any building height limit.  This gives freedom to the design community to use the many advantages of spray foam insulation on a broader range of buildings and assemblies.  In addition to its fire certification, the HEATLOK HFO Pro spray foam system offers a number of key additional performance attributes and benefits.  Offering an R-value of 7.4 at 1”-installed thickness and an R-value of 11 at 1-1/2”-installed thickness, the 2.2-lb. spray foam notably provides a higher yield.  Providing superior adhesion and compressive strength, the solution is a Class II vapor retarder at 1” thickness and exceeds ASHRAE 90.1 continuous insulation requirements at 1-1/2” thickness.  The product is also ABAA certified.

         Additional Huntsman Building Solutions HFO-based solutions, which like HEATLOK HFO Pro also benefit from the new environmentally-friendly blowing agent technology, include: FOAM-LOK spray foam insulation, FOAM-LOK spray foam roofing, and the company’s newly reformulated Pour-in-Place Foams.
