There are several types of insulation available, each with different strengths and weaknesses. They are used in combination with vapor barriers and air sealing to prevent the loss of conditioned air as well as the entry of outside air. As a loose-fill material, cellulose presents a high R-value and offers effective insulation against air leakage and infiltration and can also prevent air movement. However, like other loose-fill insulations, it is prone to settle, causing it to lose its R-value.
How Much Does Cellulose Settle?
Based on how it is installed, cellulose insulation can settle by as much as 20 percent, which can leave gaps between the insulation and a wall or beneath the floor as it compacts. However, a skilled installer can avoid most of these problems.
Professional insulation contractors are aware of how cellulose settles and typically install extra to counteract it. Called dense packing, the cellulose is compressed during installation, taking the excess air out, which expands the fibers, reducing or eliminating settling.
An inexperienced installer may not have the knowledge or equipment to provide a quality installation, resulting in substantial settling. By having a professional handle the installation, you can be sure it’s done correctly with minimal settling and long-term energy efficiency benefits.
Benefits of Cellulose
Installed correctly, cellulose insulation has several advantages over other types of insulation, including:
- Higher R-value than fiberglass
- Better air-sealing performance than fiberglass
- No harsh chemicals like spray or rigid foam
- Less expensive than spray foam
- Made from over 80 percent recycled content
- Treated with borate to provide fire resistance
Some homeowners prefer the cost-effectiveness and efficiency of cellulose over fiberglass, foam, and other types of insulation, especially those that are environmentally conscious.
