Method 5: Exposed Concrete Rough Openings
In some areas and in certain types of construction, it is not customary to leave any material, wood or plastic, in the
window or door rough opening, and only a concrete face is desired. This is easily attained by using the same method as
above in Permanent Internal Wood Frames, but decreasing the size of the buck-out (or shuttering) to make the outside
surface of the wooden form match the desired concrete rough opening size. Quad-Lock Panels are still run past the
wood form and fastened with Wind-Lock plastic plates and screws, but no nails are placed into the concrete side of the
form. The concrete side of the form is treated with a form release agent. The entire form is then braced into position for
the pour. After the pour, screws and Wind-Locks are removed, and the foam is cut with a circular saw back to the edge
of the concrete. The entire form assembly is removed, cleaned, and saved for later use.

When reaching the level to install the pre-fabricated window bucks, or rough openings, determine the sill height, and
mark it on the inside panels. Center the opening according to the plans, and cut the foam away down to the required
height for your type of buck with a hand saw. Cut the outside panels in a similar fashion. Attach blocks to the sill of
internal bucks to help position them.
Lift the pre-fabricated assembly into position, and have a crew member tack it into place using Wind-Lock style fasteners
and appropriately sized screws.
