A commercial window is a combination of frame, glazing, seals, hardware and its connection to the building. Start by distinguishing repair of an existing component from replacement of the complete opening.
Describe the problem before selecting a frame
Note whether the concern is broken glass, difficult operation, water entry, condensation or a planned appearance change. Record which openings are affected and when the problem appears.
Compare named window systems
Kawneer’s commercial window range distinguishes operating configurations, glazing options and thermal performance. Compare the published information for the actual system being proposed; a general material label does not describe every performance characteristic.
Make the comparison useful
Ask each proposal to identify the frame system, glazing specification, finish, operation and included hardware. Keep the opening schedule consistent so a price for a fixed window is not mistaken for an equivalent operable replacement.
Account for the occupied building
Explain interior access, tenant hours, furnishings near openings and any access equipment constraints. Identify what must remain usable while work is planned. These details belong alongside product selection.
Prepare a window enquiry
Provide photographs from inside and outside, approximate opening dimensions and any existing manufacturer information. State whether the request concerns glass, seals, hardware or a full replacement; final dimensions and scope still need confirmation.
Include these details
- Affected openings and symptoms
- Existing system or label
- Access and operating constraints
- Send the site details and your question
Questions about this topic
Can frames be compared by material alone?
A useful comparison also identifies glazing, seals, operating configuration and published performance for the specific system.
What if only the hardware is faulty?
Describe the faulty operation and include a hardware photograph. Ask for repair and replacement scope to be distinguished before selecting new windows.
