Fireblock Foam Spray
Quickly fill and seal large gaps around vents,
pipes, ducts and wires; and at wall-to-floor or
ceiling-to-floor joints. For use in Type V
residential construction, the foam is bright
orange for easy code identification and expands
2-1/2 to 3 times its dispensed size. Just one can
of this expanding foam yields up to fifteen large
caulk tubes.
