Enredo

Tens of thousands of homes each year are insulated with UF foam sprayed into cavity walls. The material is considered sustainable and is subsidized for its energy savings and climate benefits. At the same time, residents across the country are reporting serious health problems after installation, including headaches, shortness of breath, and eczema. In some cases, the symptoms are so severe that residents are forced to leave their homes. Experts are raising concerns about the carcinogenic formaldehyde in the foam. Zembla is documenting the complaints and investigating the health risks of this insulation method.
