Fi-Foil Co. Inc. has introduced its Thermal Barrier Blanket (TBB) system, which has been approved for installation over Icynene’s light-density, open-cell spray-foam products: Icynene Classic and Icynene Classic Max. Building codes for Type I – IV commercial buildings specify that foam plastic insulation products applied to interior space exposed or adjacent to human occupancy need to be covered with an approved thermal barrier. TBB qualifies as an alternative thermal barrier, meeting the criteria for NPFA 286. TBB also delivers 40 percent sound absorption when installed over 5 1/2 inches of Icynene Classic or Icynene Classic Max. The system can also provide additional R-value, enclosed reflective air spaces and low-emittance air films.
