In the Massachusetts climate, the more you upgrade home insulation, the warmer you’ll stay in winter — without having to raise your thermostat. The easiest place to add insulation is your attic, but adding it to your walls is also possible, although it’s a little more time consuming. Both projects are affordable ways to increase your energy efficiency for decades to come.
Insulation carries an R-value, which indicates how many hours the material can resist thermal change. Each inch translates to three hours for most insulation types, so 16 inches, the level the U.S. Department of Energy (DOE) recommends for attics in our area, provides 38 hours of protection from heat gain or loss. Rigid foam board insulation or sprayed foam insulation have higher R-values, offering more protection.
If you have plenty of space in the attic, you can unroll batts or blow in loose-fill insulation, like fiberglass fibers or cellulose, which is primarily recycled paper treated with borates for fire resistance. Laying batts can be a one-person job, while blown-in most often requires two people. One person fills the blower while the other points the hose.
If you’re residing in your home or remodeling the inside of it, the best option to increase wall insulation is to use blown-in types. Installers use a drill bit that removes a circular piece of the drywall and points the hose inside the wall. They have to drill a hole between each of the studs in the wall and fill each section separately.
If your walls are narrow, sprayed foam is an option to increase your home insulation. You can also find pressurized cans of spray foam in home improvement or hardware stores to use around small holes or cracks in the basement, your walls or in the attic. When applying it, be conservative because it expands as it dries.
