Foshan’s original manufacturer of soundproof glass: What engineering properties does Rw+Ctr acoustic glass used in construction projects possess?

Release time:

Oct 19,2026

Soundproof glass is a multifunctional specialty architectural glass that combines noise reduction and sound insulation, airtight thermal insulation, safety and explosion resistance, and weather‑ and moisture‑resistance. Unlike ordinary glass, which offers only light transmission, it employs a composite acoustic structure to specifically address urban noise pollution while also delivering multiple practical performance attributes. As such, it serves as a core material for noise control in modern residential buildings and for sound‑proofing upgrades in commercial spaces.

Soundproof glass is a multifunctional specialty architectural glass that combines noise reduction and sound insulation, airtight thermal insulation, safety and explosion resistance, and weather‑resistance and moisture protection. Unlike ordinary glass, which offers only light transmission, it employs a composite acoustic structure to specifically address urban noise pollution while also delivering multiple practical performance attributes. As such, it serves as a core material for noise control in modern residential buildings and for sound‑proofing renovations in commercial spaces.

Most users are only aware of its soundproofing capabilities, overlooking additional attributes such as thermal insulation, sealing, and safety, which leads to misaligned application choices and a subpar overall user experience.

Guangdong Haibo Special Glass Technology Co., Ltd. Leveraging Foshan’s technological edge in acoustic glass manufacturing, and drawing on the latest national standards, we conduct an in-depth analysis of the five core performance attributes of soundproof glass and their optimal application scenarios, providing a professional basis for selecting materials in both residential and commercial projects.

The five core functional attributes of soundproof glass and their corresponding national standard parameters:

First, its noise-reduction and sound-insulation properties comply with the new national standard GB 55038-2025. The standard model achieves an Rw value of ≥32 dB, while the upgraded version delivers an Rw+Ctr rating of ≥38 dB, enabling layered attenuation of low- and high-frequency noise from traffic, human speech, equipment, and more.

Second, with superior sealing and dust‑proof performance—featuring a dual‑seal, integrated bending process and an airtightness rating of Level 6—it effectively prevents sound leakage, dust ingress, and water seepage, ensuring the glass remains clear and pristine over the long term.

Third, its thermal insulation and energy-saving properties: the hollow structure achieves a thermal transmittance coefficient K ≤ 1.8 W/(㎡·K), effectively preventing heat transfer between indoor and outdoor air and reducing air-conditioning energy consumption.

Fourth, in terms of safety and explosion‑proof performance, the entire series features a homogeneous tempered‑glass plus laminated composite structure; after breakage, the glass fragments remain adhered and do not scatter, fully complying with the GB/T 15763 safety standard and effectively eliminating the risk of injury.

Fifth, with superior weather‑resistance and moisture‑proof properties, it is well suited to the hot, humid climate of South China; the hollow layer remains free of condensation and mold, and it withstands a 4,000‑hour aging test without degradation or loss of performance.

Functionally tailored to specific settings: Street‑facing residences and bustling urban spaces prioritize noise reduction and sound insulation, enhancing both living and working environments; coastal and humid areas leverage airtight, weather‑resistant properties to prevent glass condensation and mold; home and children’s spaces benefit from shatter‑proof features for enhanced safety; high‑rise apartments and sunrooms offer superior thermal insulation and soundproofing, ensuring year‑round comfort; while office and commercial spaces deliver dust resistance and noise control, fostering a clean, tranquil environment for business.

Scenario‑specific optimization plan: For low‑frequency vehicle‑traffic noise, prioritize a laminated‑hollow‑core structure to effectively target vibration‑borne sound; in humid “return‑of‑the‑south” climate zones, upgrade to a high‑strength sealing process to prevent moisture ingress; for high‑rise, elevated‑location scenarios, select thickened, explosion‑proof, sound‑insulating glass to balance safety and noise reduction; and for applications where energy efficiency and noise control are paramount, opt for standard‑compliant models that offer the best cost‑performance ratio.

All soundproof glass products from Guangdong Haibo Special Glass Technology Co., Ltd. have undergone rigorous testing in accordance with multiple national standards for acoustics, safety, and weather resistance, ensuring stable performance and compliance with relevant specifications. We can precisely tailor functional solutions to suit the specific on-site noise levels and building conditions, providing a one-stop solution that addresses acoustic insulation, energy efficiency, and safety requirements.
