Beginner’s Guide to Insulation

Have your energy bills been on the rise for what seems like no reason? Is your home drafty? You may need insulation! But where do you need it? There are a number of places to insulate in your home or building that can help save you money all year, ultimately making your home more comfortable and efficient.

As a significant source of heat loss, the attic is an ideal place to start. Of course, there are many places you should consider insulating beyond your attic, including:

  • The lower levels, like basement and crawl space
  • Exterior and interior walls
  • Floors and ceilings

A Guide on Insulating Your Home or Building

Where to Insulate: Attic

Your attic should be insulated, whether it’s finished or unfinished. In fact, attic insulation can ensure your space will be energy-efficient and comfortable all year long.

Where to Insulate: Crawl Spaces

As mentioned, the lower levels of your home or building 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.

Where to Insulate: Exterior & Interior Walls

By installing insulation in your walls, you can increase energy savings and eliminate any drafts and warm or cold spots in your home or building. Wall insulation can reduce outside noises and improve the overall efficiency of your heating and cooling systems

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. Blown-in cellulose and fiberglass are some of the best types of insulation for soundproofing.
