Insulation questions, answered by experts

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

Yes, you should add an insulative cover to outdoor water spigots in the winter for better protection against freezing. Make sure to use waterproof insulating material—something like a towel or old shirt can actually make the faucet more prone to freezing when the material soaks up rain or snow.

Not necessarily. A higher R-value simply means that the insulation has a higher heat resistance and performs better in terms of how much heat passes through the material. This can be better for some homes, or it can be too high of an R-value for other homes. Again, your climate zone determines whether the insulation is better for your home.

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.
