BOSS® 814 UL classified intumescent latex firestop sealant is a one part, elastomeric, intumescent firestop sealant that expands when exposed to fire or extreme heat, forming an insulated char. BOSS® 814 will prevent the spread of toxic gases, smoke and fire. BOSS® 814 is suitable for adhesion to almost any surface and remains flexible, making it ideal for both horizontal and vertical joints, subject to vibration or dynamic movement. BOSS® 814 can be used for interior or exterior applications and can be painted (after inspection). BOSS® 814 has been tested to ASTM E-814 (UL 1479) and meets the criteria for fire/smoke/draft stop for BOCA - CABO - UBC - SBCCI - IRC - IBC.
