The use of aluminum foil facing in construction or insulation can potentially pose health risks. Inhalation of aluminum dust can lead to respiratory issues, and long-term exposure may contribute to neurological problems. There's also a concern about the leaching of aluminum into food when using aluminum foil for cooking or food wrapping, which some studies suggest could be linked to Alzheimer's disease, although this link is not definitively proven. It's important to handle aluminum foil facing with care, ensuring proper ventilation and protective gear during installation to minimize health risks.
