Cathedral ceilings are a popular design choice in homes because they can give a room a dramatic, statement-making flair. They can also make a space feel roomier, and there’s a ton of different ways to approach them. However, there’s one particular challenge to be aware of with cathedral ceilings, insulating them.

What Is a Cathedral Ceiling?

A “cathedral” ceiling refers to a vaulted, classic look where the sides of the ceiling are tapered upwards to follow the shape of the roof. It’s a unique design choice that creates an open, airy look in a room.

Why Are Vaulted Ceilings Tricky to Insulate?

Cathedral ceilings can be tough to insulate, though. In most cases, insulation needs to be added between the roof and the ceiling itself, rather than insulating the attic in standard roof. Even with the insulation, moisture can still sneak in.

The best way to get around this is with an application of spray foam insulation.
