What’s wrong with my windows…?????
So you don’t give your window supplier a hard time…the 3 most common causes of windows and doors not opening or closing, or sticking(binding),Occur during installation are…
1)Installing the window out of square
Out of square frame easily seen at the corners of the sash.
2) The absence of packers, or the failure to put them in the right place. All windows and doors are installed into brick veneer construction by nailing into the timber frame – but there should always be packers (usually Masonite or
plastic ) between the timber window reveal and the timber house frame. Packers are used to ensure that the
frame is plumb and true when openings are not.Packers are CRITICAL under a mullion (inner vertical member)
where a heavy window (double glazed or maybe 2m x 1.8m) incorrectly supported can easily bend the reveal
and distort the openings, causing the sashes to bind.
3)Bricks compressing the jamb (side of window/door or outer vertical member). The bricklayer using the slightest force in laying up to a jamb can distort the jamb in the middle, again causing binding.
Not excuses-reality. But the binding can “usually” be fixedpost- constructionby the window supplier, but it’s not a window problem.
If you are keeping an eye on your build, watch out for packers…
