SECTION 4: DOOR FRAMES & FACADE
THE DOOR FRAME FLANGE:
The Temp-Cast “arched” door system was
designed so that a standard brick, with a
nominal thickness of 3.75”, could be easily
installed behind the door flange. However,
since brick sizes vary greatly across North
America, masons often cannot find a
suitable brick in these dimensions. In
addition, natural stone and rock often cannot
be found in these dimensions.
FACADE/ FLANGE OPTIONS:
The following techniques will allow thicker
facades to be concealed behind the door
flange.
FOR FACADES UP TO 4.25” THICK:
Glue an extra layer of 1/2” ceramic fibre
between the door frame and the heater core,
on top of the standard 1/2” layer. When
slightly compressed, this extra layer will
provide up to 3/8” additional space behind
the door flange. (Refer to Fig. 11)
FOR FACADES OVER 4.25” THICK:
For facades more than 4.25” thick, a “row-
lock” bond can be employed, in which half-
bricks are cut to approx. 3” and laid around
the door frame, fitted behind the flange.
Thicker facade materials can then be laid up
next to these row-lock bricks. (See Fig.
11a)
Alternatively, attach fire-brick “splits”
around the door frame opening with
refractory mortar, before the ceramic wool is
applied. These splits, up to 1.5” thick,
increase the space between the core and the
flange, allowing for a thicker facade material
to fit behind it. (In all cases, increase the
combustion air space under the door by the
thickness of the added splits - e.g. cut an extra
1.5” from the facing under the door if 1.5” splits
are added.)
