Building out a window frame.

Door frames have three pieces. Door and window frames span the gap between the stud frame and the wall. To build a new window frame in an existing wall. Mark and drill three pilot holes spaced evenly through the ends of the top and sill pieces at each joint using a drill driver.

Add glue and screw the frame together with 2 inch screws to build a pocket frame. They are usually 3 4 inch pine or fir with nothing special about them. While you ve probably thought of improving the quality of your glass to increase thermal insulation you can do the same for your frames saving money. If you re attaching the four pieces directly to the rough framing drill pilot holes with a 3 16 inch bit centered through each piece and screw the top on first.

It s a fairly simple project but a lot of information. For this project tom shows you how to install window trim that has reeded side and head casings plain corner blocks a thick stool and a dainty apron all of which he copied from the original trim. Use the holes in the siding to find the inside of the new frame and measure back toward center the width of the side jamb usually about 3 4 inch 1 2 inch. A window frame is the window s structural support.
