Most buyers believe that mineral wool, as a material of natural origin, is safe for humans, and there is nothing to worry about. However, this is not quite true.
Where is the danger hiding?
In production mineral wool using phenol-formaldehyde resins. They glue the fibers of rocks, giving it a shape. These same resins age over the years, begin to release phenol and formaldehyde vapors, and due to temperature fluctuations, their concentration in the air increases.
These chemicals have long been recognized as carcinogens, which belong to the 2nd hazard class (according to GOST 20907-2016 “Phenol-formaldehyde resins liquid. Specifications).
The use of mineral wool can lead to health problems such as:
- Irritation of mucous membranes and respiratory diseases (chronic bronchitis, allergic asthma, chest pain, shortness of breath, and pneumoconiosis).
- Dermatological diseases (eczema on the face, forearms, hands, as well as damage to the nails).
- Neurological and mental changes (memory disorders, insomnia, unstable emotional state).
- Diseases of the gastrointestinal tract and genitourinary system (if the substance enters the body through the mouth);
- Oncology and reproductive dysfunction in women.
Who is at risk?
First, production workers.
Research conducted scientists Clara Ross and James Loki from the University of Cincinnati, showed that during the production of mineral wool, fine dust with a diameter of 3.5–7 microns is formed. These fibers irritate the skin, eyes and respiratory tract of workers. With prolonged exposure and inhalation of microfibers, the risk of developing lung cancer is very high. That is why in production it is necessary to observe labor protection measures and use personal protective equipment.
Secondly, builders.
Builders working with mineral wool are also at risk. Toxicologist Paul Brom confirms danger of the material and recommends the use of protective uniforms, respirators, goggles and gloves for any contact with fibrous insulation.
Thirdly, residents of houses and apartments insulated with mineral wool.
Residents of cities spend most of their time indoors. A house ceases to be a fortress when unsafe thermal insulation materials are used for its walls and roofs.
In 2011, the following story took place in the city of Berezniki, Perm Territory. A new residential complex was built, but before moving in, Rospotrebnadzor discovered that the concentration of formaldehyde in the air was so high that life in the house would be impossible. The residential complex was eventually demolished.
Later it was found that the increase in formaldehyde concentration was directly related to the use of mineral wool as a home insulation. Poor-quality material began to release formaldehyde vapor into the air.
How to protect yourself?
Before choosing mineral wool as thermal insulation, it is important to carefully consider your choice. Appropriate precautions are required when installing the material due to microscopic fibers.
In addition, the potential risks associated with the use of insulation, which we mentioned earlier, should be taken into account. It is better to choose reliable modern thermal insulation materials for construction in order to maintain the health of your family members.
