A worker blows "dense-pack" cellulose insulation into an attic in Indiana. Adding insulation in ceilings and walls is such a common part of weatherization services that more than one crew has taken the nickname "dense pack." (Credit: Cellulose Insulation Manufacturers Association) |
Adding insulation is a part of almost every weatherization project. Making sure there is enough insulation in the walls, foundation, and roof-anywhere there is a barrier between the home and the outside-is one of the most important ways to make a home energy efficient.
The climatic zone where you live affects how much insulation you should have in your ceilings and walls.
