C3B and C4B Bow Roof Installation
|Polymer window roofs are designed to be
installed with auxiliary casing provided by window
manufacturer or others .See illustration below. This casing
is sometimes no more than a piece of 1"x1" pine to fill in
the space between the platform or head board and the outer
edge of the window and is used to provide fastening for the
roof. Sometimes this piece could be a little wider to better
fill in the space between the window and the roof or perhaps
higher and wider to provide space for a crown molding.
Install Auxiliary casing: install
Caulk surface of flashing and other
surfaces of roof where it meets building and window.
These bow window roofs are attached
in front by fitting over trim strip.
After the roof has been attached to
the window use galvanized or stainless steel roofing
nails to attach the roof flashing to the building. Use
the nail holes provided or drill at least 3/16" holes.
Do not nail tight: leave room for expansion.
Install the siding: do not nail
through the flashing flange.
No other finishing is recommended
and may void warranty.
Care must be taken to insure that
windows are installed in accordance with manufacturers
instructions including support by cables or knee
brackets to keep windows from sagging.
