Roof Insulation

Quality roofing insulation, if installed correctly, can increase the lifetime of a roofing system and improve the energy efficiency of the building. To perform successfully, the insulation must become an integral part of the roof assembly. Proper roofing insulation selection should be made based on several factors which include the building structure, its thermal needs, compliance with the building codes, etc. The correctly installed roof insulation of certain types will also play an important role in fire prevention.

The following types of roofing insulation are available:

  • Cellular glass insulation – composed of crushed glass combined with a foaming agent
  • Gypsum board – a non-structural, non-combustible, water-resistant, treated gypsum core panel
  • Perlite insulation board – composed of inorganic, expanded silicaceous volcanic glass, combined with organic fibers and binders
  • Polyisocyanurate – consists of organic or inorganic felt facers, glass-fiber mat facers, or glass-fiber-reinforced aluminum foil facers
  • Polystyrene insulation – expanded and extruded
  • Wood fiber – an organic insulation board
