The Best Attic Insulation of 2023
Several different types of house attic insulation are available today, ranging from spray foam, blanket, radiant foil, and foam boards, and each one will have its own benefits and shortcomings.
Blanket Insulation
This is one of the most common types of insulation, but it should not be used in open spaces due to the fiberglass particles affecting the air quality that people can breath in. Cut the thick pieces of insulation to fit between the gaps in wooden frames or pipes, wires, and other obstacles.
While this insulation is one of the most inexpensive and easiest to install, it isn’t as effective as spray foam. When installing blanket insulation, always wear a breathing mask and protective gloves.
Spray Foam
This is the primary when it comes to attic insulation. Paired with blanket insulation to insulate edges and corners better and to seal gaps in pre-existing walls. The most expensive type, though, and can be a hassle to remove; however, it is the most effective option.
This is made of liquid polyurethane, which, will then be sprayed into the cavities of your wall or attic, where it will expand and hardens into a solid mass. If you haven’t used sprayed foam before, hire a professional to install it to ensure your home has been adequately protected.
Blow-In
This refers to blowing or spraying insulation into wall cavities, floors, and attics. Methods do vary depending on the form of insulation used. Two of the most common types are fiberglass, cellulose, and rock wool, which are applied in an attic space with a machine to ensure an easy and even distribution.
