Replacement window questions
Most of the old wood sash window frames around here look like this. (It's just a basic drawing, so go easy on my lack of skills here.)
All the inside edges of those colored strips line up with each other.
I usually measure from the inside edges of the blue strips (sometimes they are wide strips instead of as shown... no big deal) and sometimes glue in a window width strip to fill in the space between the window and the frame.
The reason I do this is because we have some VERY strict and restrictive codes in parts of Florida that won't allow for much of any space between the window and the wood frame.
This is a little tricky to do.
You have to remove the blue strip (it's just nailed on)
Then dig out the pink strip (it's usually in a groove)
Now you caulk up the inside back edge of the green strip and slide the window in. The 'fins' butt against the back edge of that green strip.
Screw the window into alignment.
Here comes the 'tricky' part.........
Doing only one side (or the top) at a time, you remove the screws (on that one side only). Now you glue up the backs of your "filler" pieces, and slide them into the space between the window and the wood frame.
Wedge the filler strip up tight against the wooden frame with shims.
Let the glue dry. I use 2P-10 Jel (with no activator), so it only takes a few minutes for the glue to set up solid.
Put the screws back in.
Do this to the other sides, in turn.
In some areas where wind is not a big factor and the codes don't kill your production, I don't even bother with the glued-in strips. I just screw the windows in place. But I am telling you about the filler method so you can feel better about adding it to give you a greater thickness of wood to screw into. The fillers also limit the possible side-to-side movement of the window as it is pushed around by the wind... (the reason for our heavy code restrictions)
I know the window is only drawn a couple of inches tall.... It's just to give you an idea of how it all fits together (use your imagination)
