How does Aerolite Thermal Insulation Work?


  • Installing Aerolite directly on the ceiling in the roof space covering all areas of the roof space reduces heat loss and gain.
  • The Aerolite acts as a barrier between the very hot ceiling and the cooler home in summer.
  • In fact, in many homes, the ceiling temperature can be as high as 55 degrees on a hot summer day.
  • However, the internal wall could measure 28 degrees c.
  • Having the Aerolite Roof Insulation Installed means that homeowners will reduce the potential for the hot ceiling to warm up the home.
  • The hot ceiling acts as a barrier and will reduce the heat radiating from the ceiling by as much as 90%.
  • This will make your home 4 to 8 degrees cooler in summer.


  • In winter the ceiling space is freezing cold.
  • Installing Aerolite Roof Insulation will prevent the warm air in the home from being lost to the cold roof space.
