Abstract: Fire-resistant structures are provided having at least a 20-minute ASTM E-152 fire test rating. The structures include glass partition walls (105) having framing members (110A, 110B) formed from a gypsum-containing composition having a density of at least about 60 lbs/ft , a flexural strength of at least 30 lbs (1/2 inch thick material), and a screw-holding capacity of at least about 400 lbs. The gypsum-containing composition further contains a substantially uniform distribution of solids including about 65 wt.% to about 90 wt.% set gypsum dihydrate, about 7 wt.% to about 30 wt.% paper fiber, and about 1.5 wt.% to about 35 wt.% of one or more performance boosters selected from inorganic fiber, clay, vermiculite, and binder polymer.
