Where should I install insulation?

If you know your home needs more insulation but aren’t sure where to insulate, that’s okay. It’s what our FAQ is for! There are many different places to insulate in your home that can help you save money and live more comfortably.

The attic is one of the best places to insulate, as it is a huge source of heat loss. However, this isn’t the only place to install insulation! You should also insulate:

  • Any crawl spaces in your home
  • Exterior and interior walls
  • Floors and ceilings

Where to Insulate: Attic

Your attic should be insulated, whether it’s finished or unfinished. A radiant barrier right under the roof can help your home reflect heat from the sun and fiberglass or cellulose insulation can be installed in the floors. The right amount of attic insulation ensures your home will be energy-efficient and comfortable all year long.

Where to Insulate: Crawl Spaces

As mentioned, the lower levels of your home are great places to insulate. Whether your crawl space is ventilated or unventilated, it should be insulated (and sealed) properly. If your home has a crawl space, A LOT of air can leak in if it isn’t insulated. For a space so small, it has a significant impact on how energy-efficient and comfortable your home is.

Where to Insulate: Exterior & Interior Walls

Insulating your walls is one of the best ways to increase energy savings and eliminate any drafts and warm or cold spots in your home. Wall insulation also helps reduce outside noises and improve the overall efficiency of your AC. Spray foam, cellulose, and fiberglass are all good choices for wall insulation.

Where to Insulate: Floors & Ceilings

Installing insulation in the floors and ceilings of your home can help reduce noises between the different levels and rooms. Cellulose and fiberglass are the best types of insulation for soundproofing, and if you have an acoustical ceiling, that should be insulated as well!
