Adding attic insulation to your home is one of the best things you can do to increase your home’s energy efficiency. The right type of insulation will help keep your home warmer in the winter and cooler in the summer. When considering which type of insulation to install, you have many options to choose from.
Whether you’re building a new home or retrofitting an existing one, you’ll probably want to consider fiberglass batts for attic insulation. These are a cost-effective way to insulate walls, and they’re easy to install.
Fiberglass is a naturally fire-retardant material, and it’s also environmentally friendly. However, it can release particulates into the air, which can irritate respiratory passages and skin. You should avoid installing this type of insulation if you have children, or if you work in a crawl space.
If you have an older home, you may want to consider cutting fiberglass insulation batts into smaller pieces. This will make the insulation fit better into the walls, and you may even be able to get better grades.
When installing fiberglass batts, you will need to use the right protective gear, such as a mask, goggles, or gloves. You may also want to consider using a blowing machine for the job. Some home improvement stores sell blowing machines to rent.
Fiberglass batts come in a variety of sizes, and you may need to purchase a specific size for your attic. There are also several different types of fiberglass batts, including unfaced, faced, and loose-fill. All of them can be used for attic insulation, but only the unfaced type will provide maximum insulation.
Fiberglass loose-fill can be blown into the attic, floor cavity, or wall. It provides a good moisture barrier, but it should be installed carefully. You should also avoid using it around recessed cans, crossbeams, or pipes. It’s also a good idea to use a mesh lining for insulation.
Fiberglass loose-fill is usually sold in bags, and it’s a great alternative to fiberglass batts for attic insulation. However, you should only use loose fill when you’re able to find a contractor who can install it properly.
When installing fiberglass batts, make sure you’re using the correct materials. These include a reflective foil backing. You can also use a paper layer to help keep the insulation in place. However, a paper layer will likely not be able to stop the insulation from moving, and it may be flammable.
Whether you’re insulating a new home or adding insulation to your existing home, rigid foam board attic insulation can help you save energy. It can also keep your home comfortable and reduce air leaks.
Rigid foam board attic insulation can be found in a variety of thicknesses. The thickness of the board can make a difference in the way it performs. Typically, the higher the R-value of the board, the better its insulating power. Rigid foam can be used in your attic, basement, or wall cavities.
Adding insulation to your attic can save you 15 percent on your energy bill. It can also protect your home from outdoor temperatures. You can also use rigid foam insulation on unfinished walls and ceilings. It doesn’t change the dimensions of your home, so it’s easy to cut to fit your space. Rigid foam board is also lightweight, so it’s easy to install. It’s also flexible, so it can be used in tight spaces.
Rigid foam insulation can also help control moisture. Moisture in the attic can cause mold to grow, which can be a health hazard. If you are insulating a basement, you can also use rigid foam to reduce air leaks and close gaps.
One of the most common types of rigid board insulation is polyisocyanurate, which is known for its excellent thermal properties. Typically, it has a higher R-value per inch than other insulation types, and it’s often used on flat roofs.
Another type of rigid insulation is extruded polystyrene, also known as “Styrofoam.” It’s a closed-cell product. It’s available in thicknesses of one, two, three, or four inches. It can be purchased for $0.45 to $2 per board foot. It’s also a good choice for crawlspaces.
Polyisocyanurate rigid board is most commonly installed on ceilings, walls, and roofs. It’s known for its low cost and great thermal properties. If you’re installing rigid board insulation on a flat roof, it’s recommended that you use a vapor barrier on the roof. Vapor barriers prevent moisture from forming, which could lead to mold.
If you’re unsure which type of rigid foam board attic insulation is right for you, it’s important to do your research. You’ll want to consider the thickness, the R-value, and the installation costs.
