Air Sealing the Attic

In a climate like the one in the Toronto area, weatherization is extremely important. Approximately 60% of all heat loss happens through your roof.

Expert weatherization and air sealing of your attic involves identifying leak sources and properly sealing them prior to installing insulation. It is important to prevent air migration from the interior living space into your attic.

Prior to insulating, check for air leaks, then properly seal the following areas:

  • Attic hatches
  • Recessed lights (also known as pot lights)
  • Plumbing stacks
  • Electrical wire penetrations
  • Around plumbing stacks
  • Any light fixtures from the ceiling below
  • Ducting for fans or heating systems
  • Perimeter walls
  • Partition walls
  • Above pocket doors
  • Above lowered ceilings
  • Where the side of a cathedral ceiling meets an open attic
  • Split level discontinuities
  • Where additions meet an older section of the house
  • Above rounded corners or staircases
  • Balloon frame walls
