CONCRETE BLOCK INSULATING SYSTEMS, INC. NEVER USES UREA FORMALDEHYDE IN ITS PRODUCTS, NEVER HAS AND NEVER WILL.
Formaldehyde, which has been documented as a cause of illness in humans and shown to underperform over time, is used in concrete block insulation produced by some other manufacturers.
Because urea formaldehyde is widely believed to no longer be in use in concrete block insulation, we post this note of caution.
