Insulating your home can provide year-round energy savings. Installing the correct amount in the right places can increase comfort, too. Before you insulate, it’s important to check for and address any moisture intrusion and air leakage issues. For the best results, place home insulation in the following areas:
Install at least a total of R-38 of either batt or loose-fill insulation on the floor of the attic and around any knee walls. Loose-fill insulation is less costly. When properly installed, it can provide better coverage. To get the greatest benefit from insulating the attic:
- Be sure to air seal and make any necessary roof repairs before you insulate.
- Consider installing a radiant barrier to combat heat gain during the hot, humid summers.
- If the attic hatch opens into the conditioned living space, seal and insulate it as well.
- Make certain there’s enough clearance between any attic decking and the floor joists to install adequate insulation underneath.
Uninsulated, leaky ductwork can cause air quality issues and the loss of up to 20 percent of the HVAC equipment output. To reduce these losses, ducts routed through unconditioned spaces should be properly sealed with mastic or metal-backed tape and then wrapped in an R-4 insulation product.
A minimum of R-13 of blown-in insulation that’s installed using the dense pack technique is recommended for exterior walls in an existing home. If the wall cavities are opened up when you’re renovating, you can opt to have either wet spray cellulose, spray foam, or roll or batt blanket insulation installed instead.
Foil-faced batt insulation is appropriate for a cathedral ceiling because it offers the permeability that’s needed to compensate for the lack of attic space. A total of R-38 is recommended, and you can opt for high-density batts that allow you to add more insulating value into the standard 2-foot by 10-foot framing space.
