How To Insulate A Cathedral Ceiling From The Inside

Cathedral ceilings are a beautiful architectural feature that can add a sense of grandeur to any room. However, they can also be a source of heat loss in the winter and heat gain in the summer. If you're looking to make your cathedral ceiling more energy-efficient, insulating it from the inside is a great option.

There are a few different ways to insulate a cathedral ceiling from the inside. The best method for you will depend on the specific construction of your ceiling. If you have access to the attic, you can insulate the ceiling from the top. If you don't have access to the attic, you can insulate the ceiling from the bottom.

Insulating from the Top

If you have access to the attic, insulating the ceiling from the top is the easiest and most effective method. To do this, you will need to:

Remove any existing insulation from the attic.
Install new insulation batts or rolls between the rafters.
Cover the insulation with a vapor barrier.
Reinstall the drywall or paneling.

Insulating from the Bottom

If you don't have access to the attic, you can insulate the ceiling from the bottom. To do this, you will need to:

Remove any existing insulation from the ceiling.
Install new insulation batts or rolls between the joists.
Cover the insulation with a vapor barrier.
Install new drywall or paneling.

Types of Insulation

There are a variety of different types of insulation that can be used for cathedral ceilings. The best type of insulation for you will depend on your specific needs and budget. Some of the most popular types of insulation include:

Fiberglass
Cellulose
Spray foam

Fiberglass is the most common type of insulation used for cathedral ceilings. It is relatively inexpensive and easy to install. However, fiberglass insulation can be itchy and irritating to the skin.

Cellulose insulation is made from recycled paper. It is a good choice for people who are concerned about the environmental impact of their insulation. Cellulose insulation is also fire-resistant and sound-absorbing.

Spray foam insulation is a type of insulation that is sprayed onto the ceiling. It is a very effective insulator, but it is also more expensive than other types of insulation. Spray foam insulation is also not as easy to install as other types of insulation.

Cost of Insulating a Cathedral Ceiling

The cost of insulating a cathedral ceiling will vary depending on the size of the ceiling, the type of insulation used, and the complexity of the installation. However, you can expect to pay between $1 and $3 per square foot for materials and labor.
