When it comes to insulating your home in hot climates, fiberglass insulation is the most popular choice. It is an effective barrier against heat loss, has a low environmental impact, and provides immediate energy savings. However, proper installation is essential to ensure long-term performance. Aerosol foam insulation is also a great option, as it fits easily into cracks and gaps and forms a firm boundary that prevents heat transfer and resists humidity.
Cellulose insulation can also be adjusted to the same range, but it tends to degrade faster than fiberglass. In addition to the main attic insulation, homeowners should consider applying a radiant barrier to stop more than 80% of the radiant heat trying to enter the attic from the roof. This type of insulation works best in warm climate zones like southern Arizona. When insulating parts of your home, such as the attic, you should be aware of the different types of insulation available. Blown fiberglass and aerosol foam are two of the most common types used in attics. It is important to use waterproof materials to ensure that the insulation does not break down quickly or form mold.
Insulating blocks and similar products should be avoided in cold climates where insulation is relied upon heavily. If you are considering doing the insulation yourself, keep in mind that it requires a fairly advanced level of skill and that you must follow all safety precautions and guidelines necessary for your area. It can also be quite a large and dirty task, so it may be best to hire a professional if you are not confident in your abilities. A professional can also examine your current insulation to determine if it contains asbestos, which may be present in older homes that haven't been recently insulated.
