Doorbell Installation questions, answered by experts

If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process.

A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.

It is generally completed in a day, depending on the attic size and access difficulty.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.
