When was asbestos used in insulation?
All of these properties made it particularly attractive for home construction, and asbestos was the main material used for building insulation for the late 19th century and much of the 20th century. But as early as the 1930s, the health hazards of asbestos became clear.
Is fiberglass a carcinogen?
It also has some worried that the fibers from fiberglass are just as dangerous as asbestos -- it's sometimes referred to negatively as "man-made asbestos" or the asbestos of the 20th century. But while early research on rats in the 1970s stated that "fibrous glass of small diameter is a potent carcinogen," more modern research isn’t as sweeping in its findings [source: Montague ]. The American Conference of Governmental Industrial Hygienists, on the other hand, claims fiberglass is "Not Classifiable as a Human Carcinogen," meaning there isn't even data to say whether or not it causes cancer in people [source: Yeshiva University ]. The U.S. National Toxicology Program issued its 13th Report on Carcinogens in fall of 2014, and while its entry on Certain Glass Wool Fibers (Inhalable) states that they are “reasonably anticipated to be human carcinogens,” it also goes on to say that there is so much variation in production that full assessments must be made on a case-by-case basis [source: NTP ].

How does insulation affect fire?
The amount of insulation in the walls and ceiling/roof of a room can affect the rate of growth of a fire. Insulation will reduce heat transfer to other areas (i.e., rooms), thereby raising the temperature in the fire room. Higher temperatures in the fire room will accelerate the burning of materials in the room, resulting in an increase in the heat released into the room. The greater the amount of insulation, the higher the temperature the fire in the room can be expected to reach.
What happens when you put insulation in a fire?
Fires in insulation materials can result in the release of toxic gases and smoke, which can be fatal if present in sufficient quantities. Smoke can create problems for occupants trying to evacuate the fire area.
Why is UF insulation used in foam in place?
UF is an insulation used only in foam-in-place applications because its fragility makes it difficult to handle. It is light in weight, but its open cellular structure permits higher permeability to liquid than other plastic insulations. Therefore, it is not used in direct contact with liquids or soil. It is considered rot-proof, vermin-proof, and is somewhat less combustible than other foam plastic insulators. Its adherence to confining surfaces is weak.
How long does it take for cellulose insulation to dry out?
Many installers use dehumidifiers and allow for proper dry-out to occur by leaving the wet cellulose insulation exposed for at least 48 hours. Low moisture content (50 percent maximum by dry-weight content) is also employed to minimize dry-out problems.
What is organic insulation?

Why do plastics burn?
The rate of burning is determined by the polymer grouping and the plasticizers, lubricants, fire retardants, and other additives in the particular plastic. Foamed plastics generally burn much more rapidly than solid plastics. This is due to the large amount of surface area exposed to air in these sponge-like materials. For the most part, plasticized insulations have higher heat content per unit weight than most materials, thereby intensifying its fire hazard.

Is spray foam recyclable?
Currently, not really no. I’m sure someone somewhere has come up with a creative use for old bits of spray foam, but for the most part it will be heading to a landfill at the end of its life. Wood studs are recyclable, plywood is recyclable, rigid foam insulation boards like EPS are recyclable and even reusable, but anything with spray foam stuck to it is in all likelihood going to the dump. That means any wood, concrete or plastics that it is adhered to that could have been useful will fill up a landfill.
When did spray foam switch to climate safe blowing agents?
