Interior tile floors need periodic movement (expansion) joints. Industry guidance commonly recommends interior movement joints roughly every ____, and MORE frequently for floors exposed to sunlight or moisture.
a.50 to 60 feet
b.20 to 25 feet
c.5 to 8 feet
d.Only at the room's exact center
Explanation
Interior tile floors typically get movement joints about every 20 to 25 feet (and at changes of plane and abutting restraints), with tighter spacing (roughly 8 to 12 feet) where exposed to sun or moisture. Fifty-plus feet is too far apart, 5 to 8 feet is unnecessarily tight for typical interiors, and a single center joint ignores perimeter restraint.
