A noise reducing joist system includes a joist hanger, a joist and a sheath surrounding a bottom portion, a lower end portion and lower end side portions of the joist, the sheath and joist inserted into the joist hanger. The joist and sheath are inserted into the joist hanger. The sheath interfaces with the joist hanger rather than the joist thereby reducing noise that may be created by a sliding that might occur between the joist end the joist hanger.
