After Installation

1. Apply interior trim as desired. Adjust the windows for best

operations (if applicable). Protect recently installed units from

damage from plaster, paint, etc. by covering the units with

plastic. For casement windows, remove the shipping blocks

underneath the sash.

2. Shim the side jambs aligned with the fasteners from the corners

at each end and footer. Inspect the window for square, level and

plumb. Adjust as needed with shims. Fasten window through

side jambs and shims. Use Chart A for fastener intervals. If the

window is wider than 3’, fasten the head jamb at 24” maximum

intervals with a free ﬂoating screw. Do not shim the head. Install

vinyl plugs supplied or available through suppliers if desired.

3. From the exterior, place the new ﬂush window into the existing

frame. Ensure the window sill rests completely on the sill and

shim as necessary. NOTE: Hold window in place until fully

fastened. Fasten window temporarily through the predrilled

holes in the jamb from one upper corner. If there are no

predrilled holes, us a 1/8” tapered drill bit with 3/8” countersink

to drill a screw hole through the side jamb and into the buck

(on the interior, or exterior if insucient space). Countersink

should not penetrate the back wall of the frame. Apply sealant

to threads of a 3-1/2” screw and drive into the side jamb.

4. Insulate with ﬁberglass batting or low-expansion foam. Fill gap

with low-expansion foam around the window perimeter at the

sash position. Fill remaining cavity with ﬁberglass batting. Use

as per manufacturer’s instructions.

Quantity of pre-drilled holes may vary by brand or series.
