Insulating ceilings is one of the most cost-effective measures. In addition to reducing loss in the winter and heat gains in the summer, insulation improves comfort by bringing ceiling temperatures closer to room temperatures and providing an even distribution through- out the house.

When planning and managing ceiling insulation projects, make sure:

  • Ceiling is properly sealed
  • Correct insulation levels are selected
  • Insulation is properly installed
  • Insulation coverage is continuous and┬ácomplete
  • ventilation is maintained

Attic floors over flat ceilings are often the easiest part of an exterior building envelope to insulate. They are usually accessible and have ample room for insulation. However, many homes use cathedral ceilings or have attic knee walls that present unique insulation requirements.
