The short answer
A product warranty generally addresses specified window components under the manufacturer's written terms, while installation or workmanship coverage addresses specified field work under the installer's written terms. Neither label tells you the remedy, exclusions, labor responsibility, service charge, transfer terms, or who coordinates a claim. Compare the actual documents and map each likely issue to one responsible party.
| Compare | Product document | Installation or workmanship document |
|---|---|---|
| Typical subject | Specified frame, sash, glass, finish, hardware, or screen components | Specified removal, setting, flashing, sealing, insulation, trim, or finish work |
| Provider | Manufacturer or named warrantor | Contracting or installation entity named in the agreement |
| Evidence | Product identifier, condition, maintenance record, and claim requirements | Contract scope, photographs, closeout record, and service process |
| Questions | Does the remedy include labor and reinstallation? | Does coverage include materials, finish, water entry, travel, or service charges? |

Common questions
Can both warranties apply to one problem?
Potentially, because the cause and remedy may involve both a product component and field installation. The written documents should explain claim routing and who evaluates responsibility.
