A Homeowner’s Guide to Insulation: It’s All About Where and How Much

  • October 29, 2013

Proper insulation is essential to creating an energy-efficient home. Whether you’re building a new home or remodeling an existing home, a homeowner’s guide to insulation can help you decide where and how much to use. There are five areas of your home that should be insulated, including the attic, basement, walls, floors and crawlspace.

The type of insulation you use depends on your budget and the space you need to insulate. Loose-fill or blanket insulation are most commonly used for attics. It’s important to find and seal any air leaks in the attic before installing insulation. In North Carolina, use R-30 to R-60 insulation for your attic.

Foam-in-place insulation is optimal for floors above unconditioned garages and walls. Be sure to seal any leaks in the floor before adding the insulation. A tight seal will prevent contaminants from your garage, such as fumes from gasoline, paint and solvents, from entering your living space. R-25 insulation is recommended for floors in this region. For walls, use R-13 to R-15 foam-in-place insulation.

For your basement, use rigid foam insulation. It costs more than other forms of insulation but it’s the most effective choice for basement walls. To keep air from escaping your home through your basement, use R-2.5 to R-5 rigid foam insulation.

To insulate a ventilated crawlspace, seal the foundation walls and insulate them. This method is more effective than insulating the floor between the house and the crawl space because it allows the ductwork to remain within the house and not need additional insulation. A disadvantage of a ventilated crawlspace is that pests and water can harm the insulation.
