How to Document and Resolve Curtain Wall Defects Under an International Warranty

An effective international warranty claim for curtain wall defects begins with complete project evidence and a clear inspection process. The claimant should identify the project location, product specifications, installation date, affected sections, date of discovery, visible symptoms, measurements, photographs, and related delivery, installation, or maintenance records.

Once the claim is submitted, the supplier should investigate the cause and determine whether the defect originated from manufacturing, product dimensions, installation, customer use, maintenance, or a combination of factors. The final responsibility assessment should be supported by written inspection findings and a defined corrective-action plan.

Warranty Claim Process and Main Solutions

• Compile project information, product details, defect locations, photographs, dimensions, installation records, delivery documents, and maintenance history.
• Submit the complete evidence package for technical review and responsibility determination.
• For supplier-related quality or dimensional defects, the supplier covers replacement, transportation, and installation expenses.
• For customer-related damage or conditions, products and technical assistance are provided at cost price.
• Where both parties contributed to the problem, the correction costs are allocated through a fair and reasonable agreement.
• The service model supports projects including luxury residences, hotels, commercial developments, hospitals, and government construction from design assistance through installation and maintenance.

What Documentation Should Be Included?

A strong warranty file should connect the reported problem with the original order and project history. It should show which building, elevation, room, panel, frame, or opening is affected, when the issue was first noticed, and whether any installation, cleaning, repair, or maintenance work occurred beforehand.

Photographs should provide both close-up views of the symptom and wider images showing its exact position. Measurements, drawings, product specifications, batch or delivery information, installation acceptance documents, and records of weather or impact events can further clarify the condition. This evidence helps distinguish a factory defect from incorrect installation, site movement, improper use, or later damage.

Inspection Standards for Responsibility Assessment

Responsibility should be assigned only after the relevant technical checks are completed. Depending on the reported failure, the review may include raw material inspection, production-process checks, finished-product testing, installation acceptance, chemical safety testing, physical and mechanical performance testing, structural safety evaluation, and appearance or dimensional verification.

These inspections establish whether the supplied curtain wall met the agreed requirements and whether site conditions or subsequent handling affected performance. The results should be recorded in an inspection report that identifies the cause, recommended remedy, responsible party, schedule, and cost treatment.

Response Times, Warranty Coverage, and Service Support

For supplier-caused quality problems or dimensional inaccuracies, the stated after-sales policy includes replacement materials, transportation, and installation costs. Local after-sales cases in Africa are targeted for response and resolution within 24 hours, while domestic technical support matters are targeted for resolution within 48 hours.

Lingyin provides a 10-year warranty followed by lifetime maintenance service. Its support can cover installation guidance, on-site troubleshooting, technical coordination, and corrective work.
