One of the reasons our house was so energy inefficient is because the original windows used a weight and pulley system for opening and closing. This requires space on either side of the window to accommodate cast iron sash weights.
These balance the weight of the window sashes making them easy to open and shut - that is until the pulley ropes break.
With the other double windows Dan has replaced, the builder's rough opening has had no header. The job of the header is to bear the weight of the materials above it. Without it, sagging will begin to take place. Instead of a header, the builder of our house used the window casing to act as a post to bear the weight. We assumed this set of windows would be the same and so were surprised when that wasn't the case.
|There's actually space between the window casing and the 2x4 above it.|
So nothing was holding up the 2x4 that served as a pseudo-header.

with the blown-in insulation above the window opening.
It sagged a little bit but not too badly.
Dan's new header is a sturdy 3.5 inches by 5.5 inches.
The best part was being able to use all of our own homegrown, home-milled lumber.

Since the new window is smaller than the two old ones, the next step was to frame out the space for wall with a new rough-in for the new window.
Amazingly, there have been no unpleasant surprises to fix or rebuild, and this is probably going to be the fastest house project we've ever done.
New window shimmed and secured. The next step will be to put up the new siding.
