iNSulatiNg fireplace eNcloSure for
cold climateS
if you live in a cold climate, it is not required but highly
recommended that you insulate the fireplace enclosure to
eliminate cold air penetration as much as possible.
Insulate base of fireplace with a noncombustible insulation
rated for a minimum of 300° F. Insulating is very important
for outside wall installations over a concrete slab. If fire-
place is installed on a platform, insulation should be placed
on top of the platform before fireplace is set. Figure 9
When a fireplace is installed in a chase or on an outside
wall, enclosure should be treated like any outside wall in
a home. Insulation should be installed on the inside wall
as well as the outside wall(s). In a chase, it is also a good
idea to install a firestop at the first ceiling level above the
fireplace and enclose the chase with sheeting material.
Insulation may then be installed above sheeting material to
assure the space around the fireplace is totally protected.
