Fiberglass attic insulation is relatively easy to install. It comes in various forms, including batts, which are large, rolled-up sheets held together by reflective aluminum foil and paper that acts as a vapor barrier. While batts are the easiest to install, some disadvantages include the risk of loose fiberglass particles that can irritate the skin and respiratory system. Workers should wear protective goggles while working in the attic to avoid this.
The most important consideration is the R-value. While both types of insulation can help to control energy bills, some are better than others. Cellulose, for example, tends to have a lower R-value than fiberglass. Fiberglass tends to retain its R-value better at higher temperatures. It also retains its full R-value even at sub-zero temperatures. Additionally, both cellulose and fiberglass are easily available, inexpensive, and fire-retardant. The ease of installation offsets the disadvantages.
Another disadvantage of rolled fiberglass is that it doesn’t work with existing insulation. Old fiberglass will create gaps that will compromise the fit. Adding more fiberglass will raise the attic’s R-value to at least R-38, though it won’t be as effective as removing the old insulation. However, this option is more costly and time-consuming than tearing out the existing insulation. As a result, many homeowners opt to install more fiberglass insulation.
Fiberglass is not a good choice for people with allergies or asthma, as its particles may make them itchy and trigger coughing attacks. Moreover, it’s a known skin irritant, so wearing safety gear is important when working with this material. Luckily, you can purchase pre-cut fiberglass batts that come in a variety of thicknesses and widths. This means that you can select the right R-value for your attic.
When choosing a fiberglass attic insulation, consider its lifespan. While fiberglass is relatively durable and long-lasting, it can only last for up to 100 years under the ideal conditions. During that time, moisture, leaky roofs, and air leaks can shorten the insulation’s lifespan. It’s important to inspect your attic frequently and be on the lookout for warning signs of any insulation problems. If you notice a noticeable decrease in its lifespan, you should consider replacing the entire fiberglass attic insulation.
Another advantage of fiberglass attic insulation is its noise reduction capacity. Because it absorbs sound waves, it creates a soundproof barrier that minimizes the sound emitted from the attic. The thicker the fiberglass attic insulation, the better it is at reducing noise transmission. Noise from HVAC units and noisy pets can distract you while you are trying to sleep. The right fiberglass insulation is crucial to maintaining a healthy home. This type of insulation is easy to install, so consider the pros and cons before deciding on a fiberglass attic insulation for your home.
Fiberglass attic insulation has many advantages. It is non-flammable, which means that you can line wooden joists with it without fear of catching fire. Furthermore, fiberglass attic insulation is more resistant to moisture than other forms of insulation. And, it can even last for 100 years under the ideal conditions. It is an excellent choice for homes in humid climates. This insulation is highly effective in reducing utility bills. If you want to make the most of your attic space, fiberglass is the best option.
Cellulose is also a good choice for uninsulated wall cavities. It can be installed using a “drill and fill” procedure. If you don’t have enough room for batt insulation, you can add loose fill insulation instead. However, the benefits of fiberglass attic insulation over batts are obvious. Fiberglass is made of plastic polymers and glass, which are fire-resistant. While fiberglass is non-combustible, it can melt at temperatures of about 1000 degrees Fahrenheit. Even though fiberglass itself is non-combustible, batt insulation covered with kraft paper or foil can catch fire.
Loose-fill fiberglass is like cotton candy and contains air pockets, meaning that it does not have as high an R-value as cellulose. It is easier to install and maintain than cellulose, so it’s more cost-effective than other methods. The most important thing to remember when installing fiberglass attic insulation is that you should measure the depth of your attic before you start to install it. This is important because your insulation should be even and uniform in depth.
A few problems with fiberglass installation are well documented. In 2006, a new insulation installation protocol was introduced and requires graded installations. The HIRL, or home insulation inspection report, should also list the grade of fiberglass installation. Most fiberglass installations never receive a grade. That’s because fiberglass is a potentially harmful irritant for those without protective gear. Hence, it’s best to hire a professional to do the work.
