Fixed windows offer superior sound insulation compared to sliding windows. Fixed windows provide the best airtight seal, effectively blocking external noise; sliding windows, due to structural gaps and sealing strips, offer weaker sound insulation, with an overall noise reduction of approximately 20-35 decibels. Seamless fixed windows, on the other hand, provide more thorough soundproofing.
While fixed windows offer better sealing than sliding windows, our soundproof sliding windows feature an aluminum alloy frame and double-glazed design, achieving sound insulation of over 25 decibels. Product specifications show that our soundproof sliding windows utilize multi-layer sealing strips and a thermally broken aluminum alloy structure, effectively compensating for the gaps and defects inherent in sliding windows. We offer high-performance custom-made doors and windows, along with testing reports and warranty services.
