Thermal Barrier Solution

ICYNENE’S COST-EFFECTIVE THERMAL BARRIER SOLUTION
The International Building Code (2006 IBC) requires the installation of an approved thermal barrier over all foam plastics (including spray foam insulation) separating the foam insulation from the interior space of the building. The IBC specifically lists 1/2" gypsum wallboard as an acceptable thermal barrier material. However, most recently new technology has emerged for more cost effective thermal barrier solutions such as a spray applied intumescent coating. Icynene has tested and qualified an intumescent coating, DC-315 as an approved spray applied thermal barrier over our open-cell LD-C-50® and closed-cell MD-C-200™. This provides architects, designers, and commercial building owners with a cost effective option for exposed applications such as acoustical ceiling plenums, exposed roof assemblies, and attics connected to habitable space.
