Spray foam insulated cathedral ceilings

Homes featuring cathedral ceilings usually do not have the advantage of an attic acting as a buffer between occupied space and the outside. In addition, these assemblies are difficult to insulate well with traditional insulation. However, foam insulated cathedral ceilings with venting can address common issues and offer advantages over traditional insulation.

  • Spray foam’s air sealing properties allow foam-insulated cathedral ceilings to curb a “stack effect” where heated air escapes through the ceiling and roof and is replaced in lower levels of the home by drawn-in, outdoor air.
  • Spray foam insulated cathedral ceilings can minimize the potential of moisture or roof damage from ice damming as well as associated moisture problems such as mould.
  • Constructing the cathedral ceiling with a vented air space allows roof sheathing to dry more easily if needed.
