How can this chemical affect my health?
Acute (Short Term) Effects
Chronic (Long Term) Effects
What are safer alternatives?
- GOOD – Select a fiberglass/mineral wool insulation product with a GREENGUARD™ certificate so it has been tested and third-party certified to have no or minimal off-gassing of formaldehyde.
- BETTER – Select fiberglass/mineral wool products that use chemical or bio-based substitutes for formaldehyde.
- BEST – Consider other types of insulation, such as cellulose, cotton and natural wool.
Note: Typical exposure comes from off-gassing of the chemical, however, poorly installed fiberglass/mineral wool insulation or poor cleanup after installation could leave dust and fibers that may be a respiratory irritant as well.
Effects detailed above can occur at various stages of the product’s lifetime, not just during usage. All have been included to provide a complete picture of the chemical’s danger.
