Cathedral ceilings, or when your ceiling follows the slope of the roof instead of being flat, are beautiful features in homes. They do sometimes create a problem, however. The way they are structured makes it very hard to insulate. They don’t have very deep *spaces* to allow for insulation to be installed and they more often than not have recessed lights. The recessed lights cut into the continuous coverage of insulation causes leaks and makes it difficult to insulate.
If you have a cathedral ceiling and want to have the living space more comfortable there are options to help better insulate the ceiling. Insulation can be installed through small holes that can be sealed after blowing in insulation. Rafter insulation is also a possibility. Insulation is installed between the joists of the ceiling. This is sometimes tricky because cathedral ceilings often have canned or recessed lights. Sealing around any of these recessed lights will also make a dramatic difference no matter what insulation route you go.
