EnglishSmart Soundproof Windows
Flexible smart windows combine advanced automation with high-performance soundproofing
Overview
Designed for residential and commercial applications, our electric windows offer remote control, sensor-based auto-closing, and seamless integration with smart-home ecosystems—all while delivering weighted sound insulation up to Rw ≥ 42 dB. Whether you are upgrading an old house, securing a balcony, or equipping a high-end hotel, our solutions are built to last and easy to maintain.
Key Application Scenarios
1. Home Safety & Security
Anti‑prying alarm – instant mobile alert if the window is forced open.
Child protection – locking the opening angle via RS‑485 to prevent falls.
Pet mode – set a small ventilation gap remotely when you are away, ensuring pet safety and fresh air.
2. Weather‑Adaptive Automation
Wind/rain auto‑close – optional sensors trigger automatic closing when wind speed reaches 3.4–5 m/s or rainfall exceeds 2.5 mm/h; thresholds can be customised.
Sleep mode – schedule the window to close at a set time (e.g. after 9:30 PM) to block incoming noise.
3. Convenience & Remote Access
Remote operation – open or close windows from anywhere via the mobile app, ideal if you forgot to shut them before leaving.
Scheduled ventilation – regularly open/close windows to air out new homes or reduce odours, even when you are away on holiday.
Voice control – works with Xiaodu, Tmall Genie, and other smart speakers (Zigbee/Bluetooth).
4. Elderly & Disability Care
Timed and sensor‑based operation – windows open/close automatically, eliminating the need for manual effort.
Gas leakage detection – optional gas sensors can trigger window opening and exhaust.
App monitoring – family members can check window status remotely, offering peace of mind.
5. Commercial & Industrial
Office buildings – integrate with fire, fresh‑air, and energy‑management systems via RS‑485; windows open automatically for smoke exhaust during a fire, and pre‑cool/pre‑heat ventilation in the morning reduces HVAC energy consumption.
Hotels – KNX bus integration enables unified control of windows, air conditioning, lighting, and curtains, raising guest comfort while lowering energy costs.
Factories/warehouses – optional Zigbee gas monitors automatically open windows and cut non‑explosion‑proof power when toxic levels exceed thresholds.
6. Renovation & Balcony Sealing
Old‑house renovation – full‑window replacement with sound insulation Rw ≥ 42 dB, rich smart‑control options.
Balcony window sealing – same high‑performance sound insulation, ideal for converting balconies into quiet living spaces.
Industry Challenges We Address
| Challenge | Reality |
|---|---|
| High price | Integrated smart windows typically cost 2,300–3,200 CNY per opening sash (as of June 2026), which is a barrier for many. |
| High failure rate | Built‑in motors inside window frames overheat (cavity temperatures can reach 70–80 °C in sunlight); over 50% fail within 3 years. |
| High maintenance cost | Sealed motor units cannot be repaired – only replaced entirely. |
| Poor interchangeability | No unified industry standard (the first national standard, GB/T42407‑2023, is only now being adopted); brands use proprietary systems that are not compatible. |
| Short lifespan | Most electric openers last less than 5 years due to sun, rain, and thermal stress. |
| Low user awareness | Many customers do not understand the differences between products or what they truly need. |
| Poor sound insulation | Most smart windows use standard insulating glass, but thicker glass requires stronger hardware that most electric systems cannot support, compromising acoustics. |
| Cross‑brand “smart” add‑ons | Giants like Xiaomi and Huawei simply attach chain openers to existing windows – they improve control but do nothing for sound or thermal performance. |
| Chain opener drawbacks | Simple and low‑cost, but bulky (≥50×50 mm section, 500–1000 mm length), unsightly, and interfere with screens. |
| Swing‑arm opener drawbacks | More compact, but low thrust and locking force; cannot seal windows tightly, also external and screen‑blocking. |
Our Solution – Flexible Smart Electric Windows
Core Advantages
Motor externally mounted – placed outside the sash (section 50×50 mm, length 230 mm), making repair and replacement simple, without affecting screens or aesthetics.
Robust screw‑drive transmission – 304 stainless steel struts, corners, and gearbox ensure precise closing and consistent sealing.
Superior sound insulation – engineered like our G60 series, with high density, damping, and minimal porosity:
Weighted sound reduction Rw ≥ 42 dB
Low‑frequency performance: 63 Hz ≥ 25 dB, 125 Hz ≥ 28 dB
Reliable brushed DC motor – 24 V, complies with GB 39560 and GB 17625 EMC standards; tested for over 20,000 open/close cycles (≈5 years at 10 cycles/day), backed by a 2‑year warranty and lifetime maintenance.

Sound Insulation Performance in Detail
Unlike ordinary insulating glass units that only attenuate high‑frequency noise (>1000 Hz), Feisbao windows are acoustically engineered to reduce mid‑ and low‑frequency noise (traffic, subway, railway, aircraft, and even square‑dance music). After installation, indoor noise levels typically drop to 35–40 dB(A) even in the noisiest environments.
| Frequency | Insulation Value |
|---|---|
| 63 Hz | ≥ 25 dB |
| 125 Hz | ≥ 28 dB |
| Weighted | Rw ≥ 42 dB |
Control Methods – FAQ Highlights
Q: Does voice control require an internet connection? What if the network is unstable?
Yes, voice control requires a stable network. We recommend a high‑quality router; alternatively, use the remote control or wall panel for direct, network‑free operation.
Q: What control options are available?
Standard: wireless remote and 86‑type wall panel. Optional: mobile app, smart speaker, and RS‑485 integration.
Q: Can I open the window if the power goes out?
Yes – use a 24 V power bank, a 24 V tool battery, or the manual hex‑key override.
Q: Will voice control work with elderly family members who speak dialects?
Current smart speakers (Xiao Ai, Tmall Genie) support only standard Mandarin as of June 2026. For elderly users, we recommend the remote or wall‑panel control.
Q: How does the sealing performance hold up in winter?
Our screw‑drive mechanism enables precise closing adjustment, achieving air‑tightness Grade 7 – no draughts or wind noise.
Q: What if it suddenly rains while I am away?
Optionally add a solar‑powered Bluetooth rain sensor – it automatically sends a closing signal upon water contact.
Q: Can the windows link to fresh‑air fans or air conditioners?
Yes, via RS‑485 (Modbus) and a programmable gateway. We deliver the windows with the RS‑485 port; integration is handled by your automation partner.
Q: What is the pricing model?
Total = (area × unit price per m²) + (number of opening sashes × per‑sash price).
Glass/insulation grade: 1,000–1,500 CNY/m²
Per opening sash: 1,800–3,000 CNY (depending on size and hardware)
