What Type of Insulation Is Best?

Insulation protects your home from the elements by slowing the rate of heat transfer, both into and out of the house. This is especially crucial in winter months to keep the warmth within the walls, as well as the summer to prevent the heat from entering the cooled space. There are a number of different insulation types, but certain ones are better for specific areas in the house than others.

Roofs

Your roof is your first line of defense against adverse weather, and it's important to protect it with the right insulation. Polystyrene SIPs or Polyisocyanurate SIPs are the best options for roof insulation. Both are easy to install and can act as a moisture barrier, making them perfect for the roof. Polystyrene comes in 1-inch-thick sheets, while the Polyiscocyanurate option ranges from 1/2 inch to 2 inches in thickness.

Attics

Installing insulation in an attic can lower heating and cooling costs, enabling you to enjoy more comfortable indoor temperatures year-round. Loose-fill insulation may be the best choice for this space, as the fibers are blown into place to the desired depth and density. This accounts for attics that have lots of obstructions to work around, nonstandard joist spacing, limited headroom, do-it-yourself projects and more. Homeowners who have sufficient space for maneuvering, few issues and standard joists may find that blanket insulation, or batts, is a better option.

Garage

Batt insulation is inexpensive and easy to use, making it good for a DIY project.

Garages act as a main storage unit and get used everyday. Insulation in this space can help keep your cars and home at a more comfortable temperature. Depending on your budget, your personal needs and whether you want to hire a contractor, you'll have a few options for your garage. Batt insulation is inexpensive and easy to use, making it good for a DIY project. Blown-in insulation can also be a great option if you already have drywall installed, but no insulation. This option will call for a professional, but can be done in a few hours without any major demolition or re-installation.

Rooms

As the main points of living within the home, rooms should have the best insulation. Batts are going to be the best option for these areas as they're easy to install, and many options are fire-resistant. Spray foam can also be a good choice, but it will require a professional to install.
