Boss® 13605 CHRTV FIRESTOP SEALANT #136

Boss 136 fireblock draftstop sealant is a single component sealant and is a non-combustible filler caulking used for fire blocking applications in the annular space around wires, pipes, ducts, vents, cable lines and other penetrations to the building envelope. It is a non-slumping sealant that sets to form a hard surface. Boss 136 can be applied to any gap or penetration where the specification is non-combustible and/or ASTM-E136 rated. Boss 136 is to be used for interior applications only. The non-combustible specification is common to one and two family construction and to non-rated penetrations in multi family and commercial construction. Boss 136 is colored red for ease of inspection. In the event of a fire Boss 136 will prevent the spread of fire, smoke and toxic gases through penetration openings. Boss 136 has been tested and meets the American Society for testing materials E-136. To pass this test a material must withstand 1400 deg F without exhibiting signs of flaming after the first thirty seconds in the test apparatus. Boss 136 serves to form a ''gasket or seal against air infiltration" as required by the model Energy code in both the performance and prescriptive versions.
