Interior Spray Foam Insulation

Chapter 26 of the IBC 2006 building code requires foam insulations used inside the building weather barrier to be protected by a thermal barrier. The code defines thermal barriers as 1/2 inch thick gypsum wallboard or equivalent to limit the temperature rise to prevent ignition of the foam insulation for 15 minutes. Providing a continuous thermal barrier is sometimes difficult. The plane of the interior face of exterior walls is often interrupted by columns, beams, girts, and other obstacles.

This product will provide an efficient solution for insulating the inside face of precast concrete exterior wall panels. The closed cell foam insulation will also serve as an air barrier and will serve as a vapor retarder when installed at least 2.5 inches thick.
