Foshan’s original‑source soundproof glass factory | How effective is 35 dB, China‑standard insulated laminated glass at reducing noise in street‑facing residences?

Release time:

Aug 14,2026

On Douyin and Xiaohongshu, noise‑reduction home‑renovation projects are all the rage, with soundproof glass for street‑facing windows emerging as a must‑have bestseller for tackling road noise, traffic hum, and the din of night markets. Many residents living on busy streets and storefronts along commercial avenues suffer from low‑frequency traffic noise and high‑frequency human chatter, while standard double‑glazed windows offer only minimal sound insulation, falling short of everyday quiet‑living needs.

The new-generation national‑standard soundproof glass, featuring a hollow‑plus‑laminated composite structure, effectively attenuates both low‑ and high‑frequency noise. Without the need to seal windows or obstruct natural light, it delivers an upgraded level of indoor quietness, making it the mainstream solution for noise‑reduction renovations in homes and commercial spaces in 2025.

Guangdong Haibo Special Glass Technology Co., Ltd. As the original manufacturer of soundproof glass in Foshan, we specialize in the advanced processing of nationally‑standard noise‑reduction glass. Our products meet the latest residential building codes, deliver proven noise‑reduction performance, and are ideally suited to noisy environments across South China—whether along busy streets, in bustling urban areas, or near elevated highways.

Key new national‑standard specifications for our factory’s popular soundproof glass: It fully complies with the GB 55038‑2025 residential sound insulation regulations, delivering a weighted sound reduction index Rw+Ctr of ≥35 dB in street‑facing applications—far exceeding the noise‑reduction standards for ordinary glass. For standard 6+12A+6 insulated soundproof glass, the weighted sound reduction index Rw can reach 32–36 dB.

Upgraded 5+1.14PVB+5 laminated insulated‑glass configuration, with Rw+Ctr ≥ 38 dB, effectively attenuating low‑frequency traffic noise; integrally bent and sealed hollow aluminum spacer, achieving airtightness rating Class 6 to eliminate sound‑leakage gaps.

Glass transmittance ≥ 80%, providing noise reduction without blocking natural light and preserving indoor daylight; operates reliably across a temperature range of –20°C to 70°C, preventing condensation and mold even during damp, “return‑of‑the‑south” weather; tempered glass substrate with an inherent breakage rate of ≤0.01%, ensuring safety and compliance—suitable for both residential and commercial use.

Popular real-world applications for noise reduction: street‑facing residential units, neighborhoods adjacent to elevated highways, residents living along night market streets, ground‑floor storefronts facing the street, food and beverage outlets, office windows overlooking the street, rooms in bustling guesthouses, and noise‑reduction renovations for classrooms facing the street at schools.

Influencer‑approved noise‑reduction solutions: For standard street‑facing homes, opt for standard insulated double‑glazed glass to meet everyday quiet‑living needs at the best value; in areas with heavy traffic on elevated roads or major thoroughfares, upgrade to laminated insulated glass to tackle low‑frequency vibration noise; for small, street‑facing rooms, choose slim, nationally‑standardized soundproof glass that saves space and fits existing window frames; and for commercial storefronts, select high‑transmittance soundproof glass to balance noise reduction, natural light, and visual appeal.

Guangdong Haibo Special Glass Technology Co., Ltd. offers custom sizing, replacement‑compatible solutions for existing windows, and custom‑shaped processing. As a factory‑direct manufacturer based in Foshan, we provide integrated production with no middlemen or markups.

All soundproof glass products have passed national acoustic‑insulation testing and come with test reports and 3C certification. With full compliance documentation, they are ready for inspection and acceptance, backed by a five‑year structural warranty and long‑term, leak‑free sound performance. They offer a one‑stop solution to street‑side noise disturbances and are perfectly suited to meet the demands of trendy, noise‑reducing home‑renovation projects.
