Our one-story house has a very large window on the first floor -- appx. 72" high by 130" wide. I'd like to add a basement egress window to the room below. I'm worried that having more glass than wall on this side will somehow compromise the structure. Is that a realistic concern? E.g...
- Does cutting the foundation for an egress window put more lateral stress on the foundation above/below the egress window?
- Does having an egress window put more lateral stress on the above-grade wall?
In case it matters, the wall is a gable wall. This wall supports a beam in the ceiling of the 1st story and the foundation beneath this wall supports a beam in the floor of the 1st story, but in both cases the beams are a few feet away from the window opening and the proposed egress window. Floor joists and ceiling joists run parallel to the wall in question.
The house is 60+ years old and there is evidence of some small displacement (1/4") between the corners of the very large first floor window and the floor/ceiling.
