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.

Ensures uniform application and maximizes insulation effectiveness and energy savings.

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.
