Investigation into UF Foam in Residential Buildings

Recently there has been increased attention in the Netherlands for UF foam, an insulation material that was used in the past to insulate residential buildings. Several organisations are currently investigating where this material may have been applied and what this could mean for residents.

UF foam (urea-formaldehyde foam) was previously used to insulate cavity walls. During installation—and sometimes afterwards—the material can release formaldehyde. In higher concentrations this gas may cause health complaints such as irritation of the eyes, throat and airways.

Research in the Netherlands
Following recent reports and studies, organisations and housing managers are reviewing where UF foam may have been used. This includes collecting information about previous renovation and insulation works. The aim of this investigation is to provide clarity about the possible presence of the material and to determine appropriate next steps if necessary. Ensuring a healthy and safe living environment is always the priority.

Situation may differ per building
Initial findings suggest that UF foam has not been used everywhere and that the situation may differ from one building or project to another. This is why careful research is required. Improving the sustainability of buildings remains important, but always with attention to the health and wellbeing of residents and users.

More information
If you have questions about insulation materials or health in the home, you can find more information and advice on the websites of the Dutch public health services and national organisations. Updates will be shared once more information becomes available.
