I've always sheathed walls on the floor. But the last time I did it was the last time I ever framed.
I was laid off from my real job for a few winter months, so I went to work for a guy building condo's in Park City. I nailed mine off and I cut out the window hole. The piece didn't drop out, so I walked out on it and gave it a big ol' stomp...
...on my way to the basement floor, I remembered that I had just cut out the stairwell window, and there weren't no stairs yet! I hit flat on my back, breaking several vertibrays(sp?). At the local clinic, they found blood in my urine, so off to Salt Lake in an ambulance (my only ambulance ride, so far) At the hospital, I discovered that this low-life SOB that I worked for didn't have a scrap of insurance. No worker's comp, no liability, no nuthin'. I found this out when the hospital threw me out. I wasn't gonna die, so that ended their involvement with me.
That was 25 years ago and I live every day in considerable pain.
My point is-be careful when cutting out windows:blink:
