I. 

Install wood blocking around the entire opening.

 

The blocking must be the same height as the 

existing aluminum window frame. The blocking must 

extend to the interior far enough to provide full 

support for the sill of the new window, however may 

extend as far to the interior as desired. Set blocking 

in sealant against drywall return to prevent air 

infiltration.

K. 

Cut treated wood or PVC filler to loosely fit the 

sill cavities in the existing aluminum frame.

 This 

filler material will help support the weight of the new 

window, but should not prevent water drainage. The 

depth of the filler should be the same height as the 

tallest leg of the aluminum frame. Cut the sill filler 

to fill the entire length of the sill in both cavities. Cut 

notches in the sill filler to correspond with the weep 

holes of the existing aluminum window frame.  

L. 

Install the wood filler into the existing aluminum 

frame. 

Insert the sill filler with the notches over the 

existing window weep holes. DO NOT block any 

weep holes in the existing window. 

J. 

Apply sill flashing tape.

 Cut a piece of flashing tape 

6" longer than the existing aluminum frame width. 

Apply the tape bottom over the wood blocking so 

it overhangs 1” into the first sill cavity of the existing 

aluminum frame and goes up 3" each jamb.

M. 

Install and level sill spacers. 

Place 1" wide x 1/4-3/8" 

thick spacers on the bottom of the window opening 

1/2" from each side and 1/2" back from the interior 

surface of where the  new window will rest. Spacers 

are also required below mullions and at screw anchor 

locations.

Note: The depth of the shim should be equal to the 

window frame depth minus 1/2". Cut the shim to this 

dimension. Place the exterior edge of the shim flush 

with the exterior of the existing window. Improper 

placement of shims may result in bowing the bottom 

of the window.
