How to choose soundproof windows without pitfalls? Four key tips for glass, frames, sealing, and installation!

September-30th-2025

Is urban noise pervasive? A qualified ventilated and soundproof window is the key to maintaining the quality of your home!

From materials to craftsmanship, we analyze the key points of purchase in 4 dimensions and reject "ineffective noise reduction"⬇️

1️⃣ Glass: The “heart” of sound insulation

✅Choose a double/triple-layer hollow structure : the interlayer is filled with inert gas (such as argon) and paired with PVB interlayer film above 0.76mm, which can block 90% of medium and high-frequency noise (such as traffic noise).

✅Thickness matches the environment : Choose 5mm+5mm glass when facing the street. It is recommended to upgrade to three-glass and two-cavity glass near the airport/overpass (noise reduction > 40dB).

⚠️Avoid pitfalls: Single-layer glass or ordinary insulating glass has limited sound insulation effect!

2️⃣ Window frame: the "skeleton" of stability

Thermal break aluminum profiles are preferred : profile thickness ≥ 1.8mm, multi-cavity structure + nylon insulation strips, anti-deformation and reduce resonance noise.

✅Be careful when choosing plastic steel windows : they require built-in steel lining for enhanced support, but they are prone to aging and air leakage after long-term use.

3️⃣ Sealing: the “last line of defense” for sound insulation

✅Three -sealing design : EPDM sealing strip + middle isobaric strip + outer windproof strip are required between the window frame and the glass, and the airtightness reaches national standard level 8.

✅The more locking points , the better : at least 5-point locking system, the gap is ≤1mm when tightly closed, eliminating "leaking gaps".

4️⃣ Installation: determines 50% of the sound insulation effect!

✅The gaps in the wall must be filled : double-layer filling of high-elastic foam glue + weather-resistant sealant, no "perfunctory glue application".

✅Micro -positive pressure ventilation windows require professional debugging : ventilation volume and sound insulation need to be dynamically balanced, and non-standard installation can easily lead to secondary noise.

[Three-element ventilation soundproof window] Four core technologies, one-stop solution to the pain points of noise and stuffiness!

Three-glass, two-chamber design + aviation-grade sealing : Measured sound insulation of 30-45dB, reducing low-frequency noise (such as subway vibration) by 60%.

Thermal break aluminum window frames are wind pressure resistant to level 9 : thickened profiles + multi-cavity structure, no fear of deformation in extreme weather

German TÜV positive pressure ventilation system : With a ventilation rate of 60-120m³/h with closed windows and a PM2.5 filtration efficiency of >99%, it provides both quietness and fresh air.
