An underlayment apparatus for a floating floor, the underlayment apparatus comprising:
- a core tube;
- an integral composite underlayment wrapped around the core tube, the integral composite underlayment alterable between:
- (1) a rolled state in which the integral composite underlayment is wrapped around the core tube;
- and (2) an unrolled state in which the integral composite underlayment lays substantially flat on a support surface;
- the integral composite underlayment comprising:
- a flexible support layer having an upper surface and a lower surface;
- a pressure sensitive adhesive layer disposed on the upper surface of the flexible support layer;
- an insulating layer disposed on the lower surface of the flexible support layer;
- and
- a release layer disposed on the pressure sensitive adhesive layer.
