Product Overview
Aluminium noise reduction windows are designed to reduce external noise transmission into the interior. Noise control works at multiple levels: glass mass and thickness determine the base insulation, the insulated cavity width affects specific frequency bands, and the sealing system determines the overall performance limit.
These windows are used in street-facing residential and apartment buildings, hotel guest room windows, office building street-facing facades, school and hospital quiet areas, and buildings near elevated roads.
Core Advantages
Glass mass and cavity for base insulation:
The standard glass configuration is 5 mm + 12A + 5 mm tempered insulated. In street-facing residential buildings, the glass mass and cavity provide the base sound insulation before sealing performance is considered.
Unequal glass thickness option for low-frequency noise:
The glass configuration can be upgraded to triple glazing or unequal glass thickness combinations. In buildings near elevated roads where traffic rumble is present, unequal glass thickness reduces resonance coincidence effects compared with equal thickness panes.
Sealing system treated as a performance boundary:
EPDM sealing strips and automotive-grade sealing strips are used, and corner connection quality is included in quality control. In hotel guest room windows facing streets, the sealing system is controlled so that sound insulation is not reduced by sealing gaps.
Profile and glass range for different noise environments:
Profile wall thickness ranges from 1.4 mm to 1.8 mm, and frame width from 60 mm to 120 mm. In projects with different noise source types, the glass configuration is selected accordingly.
Applications
• Street-facing residential and apartment buildings
• Hotel guest room windows
• Office building street-facing facades
• School and hospital quiet areas
• Buildings near elevated roads
FAQ
Q: How many decibels can aluminium noise reduction windows reduce?
A: The acoustic result depends on glass configuration, sealing quality, and noise frequency. Insulated glass with multiple sealing lines provides a measurable reduction. The specific value is assessed according to the actual noise environment of the project.
Q: Are noise reduction windows effective against low-frequency noise such as traffic rumble?
A: Low-frequency noise requires greater glass mass and a wider insulated cavity. Unequal glass thickness or triple glazing can be recommended according to the noise source characteristics to improve low-frequency performance.
