After all, water is a conductor, so wet fiberglass insulation is about as effective as no insulation at all. To help fiberglass insulation dry out, place a dehumidifier or fan in the area. If possible, remove the affected batts and transfer them to a warm place to dry.
Glassfiber insulation is made from strands of glass fiber and temporarily loses its thermal resistance when it gets wet. However, if it can dry out and has not become compacted, it will retain its insulating properties. Wet insulation in a closed wall cavity will usually not rapidly dry out.
In an ideal circumstance, cellulose insulation should take around 24-48 hours to dry.
Keeping Your Fiberglass Dry
It is never a good thing when insulation becomes wet in the attic. The water will replace the air between the thin glass fibers. In turn, the insulation will reduce its thermal and acoustic insulating capabilities. You never want to ignore a problem with wet insulation in your home.
The material is designed to fill space with the “fluff” of the fibers to prevent voids and air pockets. When the fibers become wet to an excessive level, their weight increases, and the material will slowly compress and settle.
Fiberglass, a non-biodegradable substance is resistant to mold. With its sharp, ground glass, mold spores puncture before they can attach to it. Mold can grow on the fiberglass insulation backing, which is made of paper and is a mold food source. Fiberglass insulation without backing may be the best choice.
in general, blown-in cellulose insulation, surprisingly, is not found moldy." Both fiberglass and rockwool insulation (inorganic materials) have been tested. In the rockwool insulation tests showed enough nutrients to keep mold spores alive, probably from dust in the mineral fibers.
There are a few ways that insulation in the home can have an adverse health effect. Insulation can make you ill in a variety of ways, often presenting some allergies or the flu. Improper Installation--This could be poorly installed or hung insulation, or simply using the wrong material in the wrong space.
Descriptions of the problematic odor vary. The odor has been compared to burnt cookies, burnt cotton candy, and burnt glue.
Fiberglass doesn't absorb water, so no instant damage will be done to your home's structure. However, if the problem goes unfixed, that will do damage and seriously decrease the insulation's functionality. To dry fiberglass insulation out, use a dehumidifier and some fans.
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.
To help fiberglass insulation dry out, place a dehumidifier or fan in the area. If possible, remove the affected batts and transfer them to a warm place to dry. Once dry, return the insulation to the wall or floor cavity where it came from.
When resin coated fiberglass enters the sinuses or the lungs, there is the possibility that the resin could react with the soft tissues and cause inflammation or damage. It could also affect the immune system.
There is no evidence that fiberglass causes cancer in people. Animal studies have shown an increased risk of cancer when fiberglass fibers were implanted in the lung tissue of rats, but these studies are controversial because of how the fibers were implanted.
Douse the insulation in a bleach solution (1 cup bleach and 1 gallon hot water) and scrape clean with a wire brush.
If you notice any discoloration on your insulation such as brown, black, or even pink or orange particles, you are dealing with a dirt or mold problem. Insulation sheets are a solid color, so any discoloration will be obvious.
Airflow Can Cause Moisture, Dust, or Dirt To Build Up
First, your insulation might be black from air leaks. If there's air flowing into your insulation, it can bring in moisture, dust, or dirt, collecting on your insulation.
Technically, mold does not typically grow on the insulation itself. Fiberglass is not a viable food source for mold. Yet mold growth is often found on the top surface of attic insulation.
When portions of insulating material harbor mold spores, then you should replace it. Even if the material dries out, mold spores can become airborne and travel to other wet areas of the house. If you catch it early enough, then you'll only need to replace a small section of material, keeping your cost lower.
If you have loose-fill insulation that is gray, soft, and without a shine, it is probably cellulose insulation. Cellulose contains a high percentage of recycled paper and does not contain minerals. In general, it looks like shredded gray paper.
Fiberglass Melting Can Cause Problems
Although fiberglass insulation cannot burn, if it reaches a high enough temperature, it can melt. Fiberglass is rated to melt at temperatures above 1,000 degrees Fahrenheit (540 degrees Celsius).
You can insulate your dryer vent with rolled insulation. Wrap the pipe with the rolled insulation, making sure that the entire pipe is covered. Then, secure the insulation with duct tape. After this is done, caulk around the exit of the pipe on the exterior of the home to prevent cool air from seeping in.
Fiberglass and mineral wool insulation
Materials are noncombustible, and remain so for the life of the product. They require no additional fire-retardant chemical treatments—in fact, unfaced fiberglass and mineral wool are accepted as a fire block in wood frames.

Mildew (mold in early stage) and molds grow on wood products, ceiling tiles, cardboard, wallpaper, carpets, drywall, fabric, plants, foods, insulation, decaying leaves and other organic materials. Mold growths, or colonies, can start to grow on a damp surface within 24 to 48 hours.
