Specification

The Insurance Bureau of Canada (IBC) reference to NFPA 285: Standard Fire Test Method for Evaluation of
Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible
Components has led to several rainscreen wall system manufacturers to test with Roxul cavity wall
insulation. The use of SPUF insulation does not allow rainscreen manufacturers to meet this requirement.
Superior Building
Envelope Performance
Roxul Comfortbatt
™
is a semi-rigid batt insulation
designed specifically for wood and steel stud
applications for residential and commercial
construction. The stone wool-based insulation is made
from natural stone and 75% recycled content, which
gives it properties that other insulation can’t match.
It also offers superior acoustical performance to wall
assemblies and floors and can be used in acoustic
applications required by building code.
Fire-Safe Insulation For
Wall Assemblies – Won’t
Burn or Develop Smoke
Roxul ComfortBatt stone wool insulation is non-
combustible as determined by ASTM E136 and
CAN4-S114. It will not develop smoke or promote
flame spread, even when directly exposed to fire, as
most other insulation materials will.
n
Extremely high melting point of 1177 °C (2150 °F)
n
Does not produce smoke or toxic gases in the event
of a fire
n
Excellent barrier against the spread of flames to help
protect occupants and reduce property damage
n
Eliminates the risk of insulation accidently catching
fire during installation
n
Excellent Passive Fire Protection – ComfortBatt can
add up to an additional 15 minutes of fire protection
to wall assemblies
