Are you looking to upgrade the insulation in your Miami Beach home? If so, you may be wondering if it is possible to install new insulation over existing insulation. The answer is yes, but the method of application depends on the type of insulation already installed. For example, block insulation, laminated insulation, and fiberglass or cellulose insulation with loose blown filler can all be easily installed over old insulation. Blown fiberglass insulation is the most common option for existing homes, as it is cost-effective and easy to apply.
The recommendations are to have at least 14 inches of insulation, so the total cost will depend on the current depth of the attic insulation. You can measure existing insulation to determine if you have enough in the attic. If it is less than 7 inches deep, your home does not have enough insulation. In Miami Beach, a depth of 13 to 14 inches is recommended. If blown insulation was previously installed in one or more areas of your home, it is perfectly acceptable to also add rolled insulation.
Adding new insulation to the old one saves time and money, as well as limiting interruptions in the home. Adding too little material will cause continuous problems with drafts and high energy bills, while adding too much insulation can restrict airflow, create ideal conditions for mold to grow and even damage the wall. When it gets colder, warmer air from the house and attic will drain to all areas with weak insulation or gaps. Loose fiberglass or cellulose can fall on the attic floor, between walls, or other spaces that may require insulation. Attics can house a deep layer of insulation, between 16 and 26 inches, further increasing resistance to heat flow when installing blown insulation.
Boric acid is the main chemical used to treat cellulose insulation and is found naturally in seawater, fruits and plants. In 1978, Colorado adopted new building codes that required the use of insulation and other energy efficiency measures. In addition, if your home is more than 10 years old, you probably need to increase the attic insulation of your Miami Beach home. Gaps can form when spray foam is applied to blocks and rolls, reducing the effectiveness of the new insulation. Having the right amount of attic insulation can make your Miami Beach home more comfortable all year round. Built-in insulation is a cost-effective and environmentally friendly way to increase your attic's insulation, which in turn can help reduce your cooling and heating bills.
The built-in insulation slows the transfer of heat from the attic to the lower levels of the house during hot summer months and strives to keep the air warm inside during cold winter months.
