Your new Garden Window sits to the outside of your wall opening rather than the inside as your current window does.

Secondly, the inside dimension of the Garden Window is considerably smaller than the outside dimension. Since the outside dimension is larger, it will be necessary to cut back your siding. For example, a 36" aluminum window will be replaced with a Garden Window that si approximately 39" wide.

1. Remove your current aluminum or vinyl window by cutting back the siding with your skill type saw all the way around the window. Set the saw blade so that it will cut through the siding but not into the sheathing under the siding.
2. Remove the excess siding, exposing the nail fin and nail heads. Cut off the nail heads or pull the nails, then remove the window.
3. Cut back the siding to the correct size of the Garden Window. To determine where to cut, measure your new Garden Window (measure from outside edge to outside edge, not including the nail fins) width and height and then add 3 ¼" to each measurement to leave room for the 2x2 wood trim pieces. To establish where to place your cuts, lets start with the sill. Measure down 2 ½" from the inside of your sill. Note that it is better to be a little low than high. Mark this line, measure your height, center your width, measure, and mark. Take your power saw and cut back the siding to the correct size opening. You may eliminate this last step be going ahead and doing the final measurement process for the final cut before you remove your existing window.
4. Cut the 2x2 wood trim. To determine the correct length of the trim pieces, you should take the width and height of the Garden Window, as you did before, and add 3 ¼". This will insure the trim pieces are the correct lengths. A nice touch is to miter the ends to match up on a 45 degree angle.
5. Nail the 2x2 wood trim piece along the bottom of the opening.
6. Set the Garden Window in place. Be sure to center the window. Nail through the aluminum nail fins. Set the balance of the 2x2 trim pieces in place and nail.
7. Caulk the space along the side trim pieces all around the window.
8. From the inside, drill and countersink screws though the baseboard and into the sill below. The gap between the window frame liner and the Garden Window frame can be covered by a small wood trim piece or you may wish to replace the current liners with wider liner material that will cover the space between the Garden Window frame and the interior surface of the inside wall.
9. You are now ready to tile the baseboard or cover it with counter top material to match your kitchen.
10. Paint or stain all exposed wood to the desired finish.

Wood double hung windows come in two basic styles; the tilt pack balanced or the traditional block and tackle counter balance systems.

1. Remove the sash on th tilt pack window simply by titling in and disconnecting the balances. With traditional block and tackle windows, remove the inside stop with a hammer and chisel. Be careful not to damage the inside stop, as you may want to reuse it. Remove the sash and cut the ropes. Repeat this process to remove the other sash.
2. Remove the vinyl jamb liners from the tilt pack window and fill in the space with wood filler pieces. Use a putty knife to scrape the jambs and sill free from dirt or foreign material.
3. Attach the aluminum angle fin to the top of the window frame so that it is flush with the inner edge of the stops. Use the 2 ½" wood screws to fasten the bracket into the window header.
4. Now you will have to level the window sill by using two pieces of wood. Both pieces should be cut to the width of the Garden Window. One piece should be cut from a board or scrap plywood to form the base. The second piece will be used as a spacer between the outer edge of the sill and wooden base. This second piece will have to be cut to the correct height to ensure the base will level.
5. Apply caulk to all surfaces, wood and metal, that will come in contact wth the Garden Window when it is set into place.

Rough Opening – is the measurements of the bare stud framing in which the Garden Window will be installed.

Daylight Opening – is the measurements of the finished opening that is to be covered by the Garden Window.

Net – is the exact measurement of the Garden Window unit itself from outside Garden Window frame to outside Garden Window frame. Not including the nail fin.

Fin to Fin – is the measurement from the very outside edge to the very outside edge of the Garden Windows nail fins.
