Is LaPolla FoamLok Toxic?

Cured polyurethane foam is NOT toxic. However, when the foam is being applied we are basically making a plastic and thus, there are hazardous chemicals involved. Within a half hour of application and with proper ventilation there are no hazardous fumes present in the building. After curing it is an inert plastic that will last hundreds of years.

Does FoamLok™ contain Urea Formaldehyde?

No.
