    are you supposed to shim vinyl window units that have the nailing flanges ? (new construction ones)

    if so then where do you shim them at- and how do you keep the shims in place ?

    or do you just set the units on the bottom of the rough frame opening and make them level there and then nail the flanges to the exterior and call it good ?

    they are pella units, double hung, full vinyl, 32x54"

    im working on resizing the rough opening in the wall right now, almost done with one- other than figuring out how in the heck to header them

    also how do you seal across these units across the tops to keep out water ?
    with flashing metal ?
    how ?
    just nail the flashing over the window nailing flanges, or ?

    should i do the sides too ?

    thanks

    Watch for the muzzleflash!
    JUst have someone help you from the inside and center them in the hole and when you nail them dont sink the nails just snug em so they can expand and contract, thats why the nail holes are oblong, but dont ask me I havent framed in 15 years...:doah: :D

    Have someone help you hold the window in place. Draw around the flange on the outside wall. Take the window back out of the opening. Now lay a big fat bead of silicone inside the flange lines. Set the window back up on the lines and staret nailing or screwing.
    If the new window does not rest on the framing, I would definately shim under the bottom of the sill. Even the good vinyl windows will give a little if you lean down on them. Use regular shims, turned sideways, under the center of the window. Use a little silicone to hold them in place.

    Don't use nails, put your screws right through the shims where possible, and for god sakes- don't over tighten! You'll farg up the window frame and have all kinds of issues.
