Blown-in insulation may seem like a convenient and cost-effective solution for adding insulation to your home, but it comes with its own set of disadvantages that homeowners should be aware of. One of the biggest concerns with blown-in insulation is the potential for mold and mildew growth. This type of insulation, typically made from recycled paper products, is highly absorbent and can hold onto moisture for extended periods of time. If there is a leak in the roof or a high level of humidity, the insulation can become saturated and take a long time to dry out. While blown-in cellulose insulation is considered to be environmentally friendly, offering superior thermal performance and acoustic insulation, it's important to weigh the potential risks before making a decision.
Another disadvantage of blown-in insulation is the labor costs involved in installation.
While DIYers may be able to save on labor costs by installing the insulation themselves, it's important to consider the hourly rate that professionals charge for this type of work.Blown-in cellulose insulation is typically used for homes that are poorly insulated and require additional insulation. The installation process involves drilling holes in the top of each stud and blowing the material through a long hose. Alternatively, you can rent an industrial vacuum or hire a professional to remove old insulation before installing new blown-in insulation. While there are various types of blown-in insulation available, rock wool is known for its resistance to moisture and can last up to 100 years. One of the main advantages of cellulose blow-in insulation is its ability to conform to any shape or obstruction in walls or attics.
However, not all types of blown-in insulation offer the same thermal value, so it's important to do your research before making a decision. In most cases, even adding a small amount of insulation can make a significant difference in terms of comfort and energy efficiency. One of the major benefits of blown-in cellulose insulation is its ability to be installed in already closed walls without the need for major remodeling. This makes it a popular choice for homeowners looking to add insulation to their existing homes. The most common type of blown-in insulation, known as loose fill, can be blown into walls through small holes drilled in plaster or drywall.
It can also be blown into attics to fill the cavities between joists that are not insulated.
