Why Ultra HD Composite Insulation?

A non-structural composite roofing panel comprised of a top layer of EnergyGuard HD cover board (80 psi) adhered with a high-tack adhesive to a second layer of EnergyGuard Ultra polyiso insulation (20 psi). Both components have CGF facers for increased durability and mold resistance.


  • FM Approved1 for fully adhered and mechanically attached systems
  • Ideal for new construction and retrofit applications, compatible with some solar arrays and photovoltaic systems2
  • Compatible with BUR, modified bitumen, and single-ply systems
  • Resistance to mold growth, meets the requirements of ASTM 3272

Ultra HD Composite Insulation

Traditional assembly vs Ultra HD Composite assembly

When compared to a traditional assembly, using Ultra HD Composite Insulation reduces a layer of insulation and application of adhesive, therefore saving costs on material, adhesive, and labor.


Lightweight, high thermal value, composite cover board allows for less panels installed and less adhesives used versus traditional assemblies with a cover board and polyiso.
