Progressive Foam Technologies has introduced its Fullback FC Premium and Halfback H20 Premium siding insulation made of BASF Neopor thermal foam, delivering up to a 20 percent higher R-value compared with conventional EPS with the same amount of material. Neopor contains high-purity graphite particles that deliver higher insulating R-value. The graphite cell structure reflects radiant heat, reduces energy usage and keeps moisture out while letting buildings breathe naturally.
