Besides costing less to install and even less to maintain, when compared to conventional roofing systems, NCFI GRAVELEDFOAM offers several important performance features that set it apart from the competition.

• Seamless
  Because the foam is self-adhering and sprayed in place, there are no seams, channels, complex flashings or overlapping edges for water to seep through.
• Rugged
  Rigid polyurethane exhibits superior compressive strength, and when combined with the protective gravel layer, provides excellent resistance to mechanical damage.
• Weather-Resistant
  The unique combination of foam and gravel provides the best possible protection from the elements. This roof system evenly disperses precipitation and ice in the winter and enhances evaporation in the summer.
• Energy-Efficient
  Polyurethane foam is specially formulated with closed cells, which makes it one of the best insulating materials on the market today. This translates into drastically reduced energy costs for you. The foam is so efficient, it has been used by NASA to insulate the external fuel tanks on the space shuttles.
• Improved Drainage
  Because the polyurethane foam is sprayed in place, it can be tapered to improve water drainage on an existing roof. This eliminates the detrimental effects of standing water.
• UL Approved
  NCFI GRAVELEDFOAM passes the Class A fire test in accordance with Underwriters Laboratories test standard UL 790.
• Breathable
  While polyurethane foam's closed cell structure is impervious to liquid water, water vapor can diffuse through the foam, eliminating moisture vapor traps.
