Place the vinyl window in the opening. Use shims to create a snug fit of the window in the opening. Do not force the shims too tightly as that may affect the operation of the window.

Screw through the vinyl frame of the window to secure the window in place. The windows will have small vinyl inserts that are removed to access the screwing area and replaced to cover the screw. Ensure that the top, bottom and sides of the window are level. You can use the screws to adjust the window.

Rip or cut small strips of batt insulation to fill any gaps between the window and the studs. Use a shim to stuff the insulation into place. All that is left is to finish the interior with your choice of trim and to seal the exterior with aluminum and caulk.

Tips & Warnings
The wood buck size should be considered when doing new, block construction as this will reduce the window size.
While you can use anchors to mount the windows directly to the concrete, it is not recommended as the wood buck makes for easier interior and exterior trim installation, as well as ensuring a square opening.
