THE SHORT ANSWER<\/p>\n

Window lifespan depends on more than the frame material<\/h2>\n

These ranges are useful starting points, but they are not expiration dates. A well-made window that is measured, flashed, sealed, supported, and insulated correctly can continue performing well beyond a typical estimate.<\/p>\n <\/div>\n

WHY WINDOWS FAIL EARLY<\/p>\n

The window is only as dependable as the opening around it<\/h2>\n

Modern glass and frames are engineered for long-term performance. Early trouble often begins where the window meets the home: a poor seal, missing insulation, inadequate flashing, or an opening that was never properly leveled.<\/p>\n
