When it comes to roofing insulation, you have a few different options. Besides the traditional materials of cellulose, fiberglass, and batts, there are also some more advanced types of products. You’ll need to find the best material for your budget and your specific needs.
The roof insulation material you use should be suitable for your home and the climate in your area. This will make your roof more durable and help you save on energy costs. Also, it’s important to be careful about how you install the insulation. If you don’t use the right type, your insulation could become a fire hazard. Luckily, you don’t have to be a professional to complete this project.
Batts and rolls are popular for larger areas, but you can also opt for loose fill insulation if you’re doing a do-it-yourself project. Loose fill insulation can be layered over existing roofing materials. It can also be used in attics.
Fiberglass blown-in roof insulation is another option, and it is very lightweight. However, it can settle more than other roof insulation options, so you’ll want to check your roof before installing this type.
Fiberglass batts can be purchased with or without a foil facing. They come in many sizes and thicknesses, and you can stack them in your attic to reach the desired level of insulation.
Fiberglass is less expensive than other insulation options, but it can irritate your skin. Sheep’s wool is also a good choice for insulation, but it is not recommended for direct contact with light fixtures. Wool is not as effective as other insulation materials at insulating heat, but it does have a higher R-value.
Cotton is a good option for blocking airflow. Cellulose loose insulation is another type, and it uses recycled paper. Unlike other materials, it has an R-value of 3.2 to 3.8. Cellulose is treated to be resistant to insect infestations.
Rigid foam insulation is also available, and it can be attached to the attic side of a hatch. A secondary layer can be plywood, wood fiberboard, perlite, or gypsum board. These can be combined with a waterproof rubber membrane.
Lastly, there are the synthetic materials, such as polyisocyanurate and plastic foam. These insulation products are less expensive than extruded polystyrene, but they can delaminate when they are exposed to high traffic. In addition, they can absorb moisture when they are subject to leaks. Using a reflective blanket is another option, which can help reduce your energy expenses.
Choosing the correct roof insulation material will be the first step to your DIY project. Depending on your needs, you may need to purchase two or more layers of insulation to achieve the R-value you require. To determine the best product for your needs, compare prices and the label. You should also be aware of the manufacturer’s warranty. Some companies offer lifetime warranties on their products.
Whether you are completing a do-it-yourself project or hiring a contractor, you’ll need to choose the right material. Whether you’re installing batts, rolls, or loose fill, the insulation you choose will be one of the most important parts of your home.
