Commercial Blanket Insulation is used as a thermal or acoustical insulation in commercial buildings where wide rolls of unfaced insulation are required, such as retrofitting a warehouse. Commercial Blanket is a uniformly textured tan blanket made from inorganic glass fibers bonded with thermoset formaldehyde-free resin. A range of R-Vales are available to meet energy code requirements. Commercial Blanket Insulation can be used in roofs and sidewalls as a sounds layer over the unfaced side of Metal Building Insulation. Available up to 10' thick, Commercial Blanket is also used in post frame construction and may be installed over old roof decks (BUR and metal) prior to application of a new standing seam roof.


  • Lowers energy use
  • Noise control
  • Increased comfort and thermal properties


Product is normally applied over or between the structural members of the building and held in place by the covering sheets or insulation support system. When using high R-value systems, it is recommended that the cavity between the exterior metal sheet and the faced fiber glass insulation should be completely filled with Commercial Blanket Insulation.
