9. Technical FAQ (Expert FAQ)

Q1: What materials best balance flexibility, durability, and chemical resistance in door bottom draught excluder production?
A: Silicone rubbers (VMQ) and TPV are optimal for balancing temperature stability, low compression set, and chemical resilience. Reinforced with corrosion-resistant aluminum or stainless steel carriers per ISO 4892-2 for longevity.
Q2: Which industry standards should be met for commercial installation?
A: ISO 9001 for quality management, ANSI/BHMA A156.22 for door sealing hardware, and fire safety standards (UL94) are essential. Cleanrooms should also reference ISO 14644-1 for particle performance.
Q3: What is the typical installation clearance required for an effective under door draft stopper?
A: For optimal sealing, provide 3-7mm gap coverage with at least 1mm compression overlap. Fit should be tight but avoid excessive drag, which leads to premature wear.
Q4: How does cycle durability testing work for draught excluders?
A: Samples undergo repeated mechanical opening/closing per ANSI/BHMA simulation. Leading models such as Qzseals are validated beyond 320,000 cycles, retaining over 90% sealing function post-test.
Q5: Are there fire-retardant grades for door bottom seal strips?
A: Yes. Modern door bottom seal strip products offer silicone/TPV grades certified to UL94 V-0 or V-1, ideal for use in regulated fire-safety environments.
Q6: Can under door draught stopper be retrofitted to glass, metal, and wooden doors?
A: Absolutely. Multi-profile extrusions and universal mounting hardware allow for adaptation to wood, aluminum, steel, and glass doors. Self-adhesive or screw-mount options available.
Q7: What is the warranty and after-sales service for Qzseals products?
A: Qzseals guarantees a 5-year warranty, technical guidance for installation, and responsive support (normally
