BOSS® 814 Intumescent Latex Firestop Sealant

  • In the event of a fire, BOSS® 814, a one-part, elastomeric, intumescent firestop sealant will expand to form an insulating char that prevents the spread of fire, smoke and toxic gases through construction openings.
  • Formulated with non-combustible, inorganic materials.
  • Remains flexible when cured, making it ideal for both horizontal and vertical joints that are subject to vibration or dynamic movement. With its excellent adhesion properties, it is particularly suited for sealing walls and floors that have been penetrated by pipes, conduits and electrical cables in all types of construction. It can also be used to fill interior voids around HVAC, plumbing and framing.
  • BOSS® 814 Intumescent Latex Firestop Sealant meets or exceeds ASTM E-814 (UL 1479) and meets the criteria for fire/smoke/draft stop for BOCA, CABO, UBC, SBCCI, IRC and the 2003 International Building Codes. The product is very easy to apply using a standard caulking gun or trowel and cleans up with water, prior to curing.
  • It can be used for interior or exterior applications and can be painted (after inspection).
  • BOSS® 814 is available in 10.1 Fl. Oz. and 28 Fl. Oz. cartridges, 5 gallon pails, 20 Fl. Oz. sausages, and 11 Oz. Net Wt. aerosol cans.
