When a fire ignites, it spreads by air movement between rooms, through unsealed penetrations in the walls and lumber. Building codes require the use of a draft stopping sealant in these spots, to reduce the potential spread of fire and help isolate flames to a single room.
Engineered to seal with a single application in temperatures as low as -4°, Fire Block Extreme is our most popular fire block foam, designed to work well with our Extreme Temp window & door foam, in locations requiring the orange color for easy identification by inspectors.
TYTAN Professional Fire Block Extreme is part of the TYTAN UP! Whole Home Air Sealing system. When used properly, this system can provide measurable improvement to blower door test results for air exchanges per hour.
