What are the dangers of fiberglass insulation?
“Fiberglass insulation should never be left exposed in an occupied area, according to the American Lung Association,” says ALA’s Godfrey. “Exposed fiberglass insulation, once in the air, does cause respiratory reactions, such as dry, scratchy throat and coughing, as well as acting as a skin and eye irritant.
Is fiberglass insulation better than cellulose?
When it comes to air infiltration cellulose is a better choice because it has 38% better air infiltration than fiberglass. Cellulose properly insulates the attic because it forms a dense continuous mat and keeps the air moving within the insulation. You can try Ceramic rope instead of fiberglass. 20 views
Is fiberglass insulation bad for the environment?
Unfinished parts of the home may still have exposed fiberglass insulation, and it can cause the same skin and airway irritations as listed above. Is Fiberglass Harmful to the Environment? Given the properties and risks of fiberglass, it is clear that it is a potential environmental hazard. Just consider the problems facing the wind energy industry.
Is compressed fiberglass insulation really so bad?
Incompletely filled cavities are a problem. Gaps are a problem. But you can compress fiberglass insulation quite a bit and it still works just fine. The North American Insulation Manufacturers Association (NAIMA) has a little two-page document about compressing fiberglass insulation.
Is fiberglass insulation fireproof?
Fiberglass insulation is made of glass combined with plastic polymers and is naturally fire-resistant. However, you need to be careful with batts that are backed with foil or paper as these materials can burn quickly.
What insulation is combustible?
Cellulose insulation Products are largely made of newspaper, which is highly combustible. Even though it's heavily treated with fire-retardant chemicals prior to installation, it is a recognized fire hazard by the Consumer Product Safety Commission (CPSC).
Is insulation combustible material?
While mineral-based insulation materials are non-combustible, or low in combustibility, the paper or foil backing surrounding the insulating material may be flammable.
Is batt insulation considered combustible?
If you are considering batts, you must be wondering whether they are combustible. Batt insulation made from fiberglass isn't flammable, but the fiberglass will melt if the fire gets too hot. If the batt is covered with kraft paper or foil, though, these materials will burn, only melting the fiberglass.

What is fiberglass insulation?
Fiberglass is one variety of insulation that is made from fibers of glass, often with a polyester coating. The fiberglass may be used as a loose-fill or installed in batts, blankets or rolls. In blanket or roll form, it has a fairly unique fluffy look to it. This has drawn some concern to homeowners who think it might be flammable.

Types of Insulation and Their Ignition Temperature. As you can see, fiberglass and mineral wool insulation are some of the best when it comes to preventing fire ignition. Additionally, when factoring in cost, fiberglass insulation is definitely in the best tier for most people.
Why does fiberglass insulation make you itch?
Fiberglass insulation can cause itching because it is actually made with glass fibers. These glass fibers can get into your skin and your lungs, causing irritation. For this reason, fiberglass insulation is not a good choice for people with certain allergies or sensitivities.
What happens when fiberglass melts?
Additionally, when fiberglass melts it can spread heat to other materials that might be more flammable, like wood sheathing. Lastly, burned fiberglass insulation can send particles into the air, which can cause exposure to irritants like silica and boron.
What temperature does fiberglass insulation melt?
Fiberglass insulation is rated to melt at roughly 1,400°F or 760 Celsius. The most common area that fiberglass insulation will catch fire is typically around electronic devices such as heat exchangers. There have been numerous reports of fires in homes as a result of this.
What is the R value of a fiberglass batt?
For example, fiberglass batts and blankets have R-Values of about 3.3 per inch, 44% more effective than loose-fill fiberglass, which has an R-Value of 2.1 per inch. Depending on the severity of the burn, fiberglass batts clearly have the most potential for R-Value loss.
What is the most popular insulating material?
Fiberglass is one of the most popular insulating materials used in house construction, today. It’s a very low-cost material and it’s easy to stuff into spaces between interior and exterior walls and mute the radiation of heat from inside your home to the outside world. It is also used in boats, aircraft, windows, and roofing.
Is carbon fiber the same as fiber?
Fiberglass is often confused by people with carbon fiber, but the two materials are not in the remotest bit chemically similar. Even though they make look similar in certain applications, carbon fiber is made out of carbon, as the name suggests, glass, on the other hand, is made out of Silicon Dioxide and contains no carbon at all.
Is fiberglass a trademark?
Fiberglass is actually a trademark. But rather like Hoover or Kleenex, also both trademarks, it has become associated in the public mind with one thing – that is the pink insulating material used in walls and to line the attic of the average house as an insulating material. (Though it is actually used in other forms for other applications as well.)

Rather than using material that has high thermal resistance (like fiberglass), radiant barrier insulation is made of a foil-like material. This material helps radiate heat AWAY from your home, keeping it cool in the Dallas heat.
What is spray foam?
Spray Foam. Spray foam is a different material from cellulose and fiberglass. When applied it has the texture of shaving cream but when it cures it becomes an impenetrable barrier. It’s great at sealing up even the smallest cracks and preventing moisture.
Is cellulose insulation combustible?
Cellulose is another commonly used material and one of its significant qualities is that it is made of recycled paper fiber. So, if you are looking for “green insulation,” cellulose is the one. However, because it is made of paper, it will be combustible, even though it is heavily treated with fire retardant.
Is fiberglass insulation fireproof?
In addition to that, it is non-combustible, meaning it is inherently fireproof and does not need to be treated with a fire retardant. That being said, SOME fiberglass facings, such as kraft paper and foil are combustible. “Faced insulation” is insulation that has a paper vapor retardant, used for moisture control. Facings can be found in batt insulation and must never be left exposed.
