The present gated barrier includes a threshold and an isolator on the bottommost surface of the threshold to space the gated barrier from the floor. The isolator includes a compressible layer made of a textile. In a second embodiment, the isolator includes a relatively compressible layer made of a textile and a relatively incompressible layer made of a plastic. The isolator protects the floor against scratches and dampens the noise that is made when the gate is shut.
