In many cases, the manufacturer stands behind the unit, but not the labor that put it in your wall.

If the installer says "lifetime warranty," ask whether that means lifetime on the glass, lifetime on the frame, or lifetime on the workmanship, since those can be very different promises.

Some warranties are full coverage for a set number of years, then prorated after that, which means the replacement value drops as the window ages.
