I know it has probably been discussed before, but how tightly can we curve gypboard? I am looking at a spec house job with a bumpout staircase with the inside corners at the landings being 32″ radius. I am now trying to get some info on something called “1/4″ hi-flex” board, which sounds like the right direction. Maybe two layers of that on studs tightly packed at, say, 6″ centers at the curved parts. From the low landing the curved corner runs up about 17 feet, and the high one has a vertical run of about 10 feet. The 32″ radius is seen in plan view. A quarter-circle tangent to adjacent walls.
