Insulation questions, answered by experts

The benefits of insulating your pipes include preventing freezing, sweating, and condensation. In addition, insulating your pipes can make your home more energy-efficient by keeping your pipes from losing or gaining heat. You’ll be able to turn the temperature of your water heater down by two to four degrees Fahrenheit. According to the U.S. Department of Energy, this can reduce energy costs by 3% to 4% per year.

Yes, spray foam insulation can be applied to your ductwork and effectively insulate your ducts. Blanket insulation is the easiest insulation product to DIY since it is easy to wrap around ducts. However, spray foam insulation can also benefit your HVAC system if applied to air ducts.

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

Once installed, injection insulation requires little maintenance, but periodic inspections for air leaks or moisture buildup are recommended.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.
