Frequently Asked Questions (FAQs)

How do I find reputable double glazing supplier factories or manufacturers?
Start by searching online directories, trade platforms, and attending industry trade shows. Check reviews, request recommendations, and look for industry certifications to ensure credibility. Always verify their business licenses and client references before proceeding.

What should I consider when comparing different double glazing suppliers?
Focus on product quality, pricing, lead times, warranty terms, minimum order quantities, and after-sales support. Also, consider supplier location, customization options, and their ability to meet your specific requirements.

How can I assess the quality of a manufacturer’s double glazing products?
Request product samples, inquire about certification standards (like ISO or CE marks), and ask for detailed specifications. You can also request customer testimonials or case studies to better judge long-term performance and reliability.

What are the most common payment terms when working with double glazing manufacturers?
Typical payment terms include deposits (often 30% upfront, 70% before shipment) or letters of credit for larger orders. Always clarify payment terms before signing agreements and never pay the full amount upfront to minimize risk.
