Is insulation a hazardous material?

Insulation materials can contain a range of hazardous chemicals. Those of highest concern include halogenated flame retardants, formaldehyde-based binders, organotin catalysts, isocyanates, and blowing agents with high global warming potential.

Is fiberglass cancerous?

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.

How can you tell if insulation is wet?

While a contractor may use a moisture meter to detect wetness in a wall, the consumer may have to open the wall cavity to determine if it is wet and allow the insulation and adjacent materials to dry.
