Where Do You Need Insulation in a House?

Whether it’s for new construction or for aging homes with outdated insulation, we’re often asked where a home’s insulation can be improved or where it’s needed. When determining where insulation is necessary, the best first step is to perform a home energy audit. This gives our team the chance to assess your home and where you have efficiency issues, and then we can go about fixing them and helping to improve your home’s comfort and efficiency.

Schedule your home energy audit or insulation consultation in southeastern VA today by filling out the form in the sidebar or calling 757-828-0024.

Where You Need Insulation

On a general level, insulation should be installed in all areas of your home:

Where to Insulate: Attics

The attic is one of the best places to insulate in your home because it can be a huge source of energy loss. Knee walls (vertical walls with attic space behind them) and floors need to be insulated. Knee walls tend to be very leaky and energy-inefficient. The ceiling should also be insulated with foil, which helps your roof reflect, rather than absorb, heat from the sun. This keeps your home a lot cooler and more comfortable. In fact, homes with radiant barrier installed are about 10 degrees cooler than homes with no insulation in the attic!

Best insulation to use: radiant barrier (reflective); fiberglass blanket system; cellulose

Where to Insulate: Basements

Don’t overlook the foundation of your home when it comes to insulation installation. Insulating the basement can save you hundreds of dollars annually—and insulating the walls can help your home stay more comfortable year round. For sound control purposes, you can insulate the basement ceiling.

Best insulation to use: fiberglass; cellulose; spray foam

Where to Insulate: Crawl Spaces

If your home has any crawl spaces, it’s important that you insulate them. Crawl space insulation can help reduce air leaks, control moisture problems and prevent issues like frozen pipes, soil vapor intrusion and more. The walls should be insulated in unventilated crawl spaces. For ventilated crawl spaces, insulating the subflooring and floor joists is more important. When insulating a crawl space (ventilated or not), moisture control is vital—air sealing is required.

Best insulation to use: fiberglass and spray foam

Where to Insulate: Walls

Both interior and exterior walls should be insulated (as a professional insulation company will tell you). Behind your interior walls, there are wires, pipes and ductwork. It may be recommended to insulate around these too. In fact, ducts are almost always insulated.

Best insulation to use: fiberglass; cellulose, spray foam
