Tips for Insulating a Cellar

Rockwool insulation, as installed in a cellar

Danny and Joe welcome callers’ questions each week on the Today’s Homeowner Radio Show.

Here’s a question from a fan who has an insulation problem:

Marj in New York says, “I need your help. We built a new house in 2006. We found a builder using our local family-owned lumber company; however, our builder took off before finishing the house.”

Now, Marj and her husband must finish the work — and time is of the essence.

“We need to insulate our cellar so that we can get a certificate of occupancy,” she says. “My husband and I will be installing the insulation.

“A friend advised us that the easiest way to insulate our cellar is to use blanket insulation. What is this and where can I get it? Can you offer us any advice?”

Blanket insulation comes in batts or rolls in the store, so all you have to do is open the package at home, unroll the insulation, and install it.

This differs from the time-intensive installation methods required for blown-in and spray foam insulation, both of which aren’t do-it-yourself-friendly tasks.

The home center has a variety of insulation types, but we recommend mineral wool insulation. It’s more moisture-resistant and doesn’t irritate your skin, like other types of insulation — which do-it-yourselfers can certainly appreciate.

Marj can visit Rockwool’s product page to find the insulation solution that meets her needs and then she can talk to some installation companies to gather some labor prices.
