A B757 captain noted that windshield delaminations are not tracked by maintenance for area increases...

Narrative:

Departed gate with a known window defect. For several months now I have been writing up windows per the far's for delamination. In all cases; the mechanic comes up; measures the delamination and then we are told the window is good to go with no further action taken. There is no log created to check it after so many hours; no one keeping on eye on it etc. There is no yellow dot on it like a dent on the fuselage to prevent multiple write ups. So once airborne I write it up again because I am not sure that it didn't get bigger and isn't legal for the next flight. I am very uncomfortable with this procedure of the window being unmonitored by maintenance. If every pilot were doing his/her job correctly per the far's; the delamination would be written up on every leg. And that is a huge waste of the pilots time and the mechanics time as well as the company's money. A dent in the aircraft is a defect and it is noted in the log and a yellow dot is put on it. A delaminated window is a defect even if is within tolerance (which I think is 3 inches) and should also be noted in log book for regular checks by maintenance to make sure it is not expanding. There is no reason we should be departing with a known defects unless it is logged in log book for further evaluation at a later date.
