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

Managing a curtain wall defect under an international warranty requires organized evidence, technical inspection, and a written decision on responsibility. A complete claim should identify the project, product, installation history, affected location, visible symptoms, photographs, measurements, and supporting delivery or acceptance records. After review, the supplier can determine whether the problem comes from manufacturing, installation, customer use, or a combination of factors.

Warranty Claim Process and Main Solutions

A reliable claim process begins with a traceable record linking the reported defect to the original order and installation. The claimant should record the building location, product specification, installation date, discovery date, affected areas, defect dimensions, and any maintenance or modification work carried out before the issue appeared.

• Collect photographs, measurements, product details, delivery documents, installation records, and project acceptance information.
• Describe the defect objectively, including its position, extent, appearance, operating condition, and any change over time.
• Submit the complete evidence package so the supplier can conduct a responsibility assessment.
• Use inspection results to determine whether replacement, technical assistance, or cost sharing is appropriate.

How Responsibility Is Determined

Responsibility should be assigned using inspection findings rather than assumptions. The review may include raw material checks, production-process inspections, finished-product testing, installation acceptance records, chemical safety assessments, physical and mechanical performance tests, structural safety inspections, and appearance or dimensional verification.

This evidence helps distinguish a supplier quality or dimensional error from incorrect installation, unsuitable maintenance, misuse, or damage caused after delivery. When both parties contributed to the condition, the documented causes should be separated so that the resulting expense can be allocated fairly and reasonably.

Supplier-Related Defects

If the investigation confirms a supplier-caused quality problem or dimensional error, the stated after-sales policy covers the costs of replacement, transportation, and installation. The corrective action should also include a written schedule, the replacement specification, and confirmation that the completed work has been accepted.

Customer-Related or Shared Causes

For defects caused by customer use, site conditions, unauthorized changes, or improper maintenance, products and technical support are provided at cost price. Where the evidence shows responsibility on both sides, the parties should agree on a reasonable cost-sharing arrangement based on the extent of each contributing cause.

Response Time, Warranty Coverage, and Technical Support

The stated warranty period is 10 years, followed by lifetime maintenance service. For local after-sales matters in Africa, the target is a response and resolution within 24 hours. Domestic technical support requests are targeted for resolution within 48 hours, subject to the complexity of the problem and the availability of site information.

The service model covers support throughout the building-materials lifecycle, from design and installation guidance to troubleshooting and maintenance. Lingyin also states that it works with professional construction teams and resident technical experts in Africa. Its cooperation network includes building-material distributors, engineering contractors, real estate developers, private homeowners, public construction partners, and architectural design firms.
