Fire Block Foam is a specially designed, closed cell, insulating foam used to fill

gaps and resist the migration of fire and hot gasses in Type V residential (wood frame)

construction. This foam is orange in color and easily identifiable on the jobsite. Best for use

where a fire rated foam is needed such as electrical, plumbing, and HVAC penetrations. Fire

Block Foam is UL Certified and ASTM tested.

• Specially formulated for fire blocking applications

• Orange color identifies Loctite Fire Block Foam as an approved fire block product for

Type V construction

• Fire rated and tested in accordance to:

• UL 723 in accordance with ASTM E84

• ASTM E814 (modified)

• NFPA 286

• Conforms to IRC (International Residential Codes) and IBC (International Building Code)

fire blocking requirements

Loctite Fire Block Foam is designed specifically to help prevent the spread of fire and smoke through concealed service

penetrations in Type V construction, and occupancy groups R3 and R5 buildings, in accordance with fire blocking requirements

outlined in the International Residential Code and International Building Code. "Fire blocking" is defined by the IBC as the use

of approved building materials installed in concealed spaces to resist the migration of fire and hot gases. Fire Block Foam may

also be used for gap filling purposes around wiring and plumbing penetrations, HVAC duct work, basement and crawl space

drafts, sill plate, attic hatch, and is for both interior and exterior use.

• Not for use as a “firestop” product and should not be used in hourly fire rated assemblies that require fire stop products

• Not for use in Type I through Type IV construction

• Some local building codes may restrict the use of polyurethane foams as “fireblocks”. Always check local building codes.

• Do not cut foam. The fire-blocking capabilities are greatly compromised if foam is cut or damaged.

• Should not be used in contact with chimneys, heater vents, steam pipes, or other areas which could be subjected to

surface temperatures greater than 187°F

• For cold weather application, product should be stored above 41°F (5° C) at least 12 hours before application

• Despite significantly higher UV resistance, it is still recommended to protect the foam from UV radiation. Exposed foam

should be coated with a protective covering or coating

• Do not store product on its side; cans must be stored upright at all times

• Does not bond polyethylene, polytetrafluoroethylene (PTFE)/Teflon

or siliconized surfaces

• Certain materials such as rubbers and plastics may have bonding difficulties. Test before use

• Flexible sheet goods

Technical Data Sheet Revision: April 1, 2023 Supersedes: NEW Ref. #:607448 STORAGE & DISPOSAL Product must be stored vertically, not horizontally on its side. Store in a cool, dry place for maximum performance and shelf life. Do not store below -4°F (-20°C). Below this temperature the product valve may spontaneously open, resulting in leakage. Product may be stored for a maximum of 1 week at -4°F (-20°C). For extended storage periods (longer than 1 week), store between 41°F and 77°F (5°C and 25°C).
