How to choose soundproof windows without making mistakes? Four core strategies for glass, window frames, sealing, and installation!

Is urban noise penetrating everywhere? A properly ventilated and soundproof window is key to protecting your home's quality of life!

From materials to craftsmanship, we break down the key points for purchasing from four dimensions, helping you avoid "ineffective noise reduction" ⬇️

1️⃣ Glass: The "heart" of sound insulation performance

✅ Choose double/triple hollow structure : The interlayer is filled with inert gas (such as argon) and paired with a PVB membrane of 0.76mm or thicker, which can block 90% of mid-to-high frequency noise (such as traffic noise).

✅ Thickness matching environment : Choose 5mm+5mm glass for street-facing areas, and upgrade to triple-glazed double-cavity glass for areas near airports/elevated roads (noise reduction > 40dB).

⚠️Avoid these pitfalls: Single-pane glass or ordinary double-glazed glass have limited sound insulation!

2️⃣ Window frame: The "skeleton" of stability

✅Priority given to thermally broken aluminum profiles : Profile thickness ≥ 1.8mm, multi-cavity structure + nylon thermal insulation strip, resistant to deformation and reduces resonance noise.

✅ Be cautious when choosing PVC windows : They require built-in steel reinforcement for support, but they are prone to aging and air leakage with long-term use.

3️⃣ Sealing: The "last line of defense" for sound insulation

✅ Triple sealing design : EPDM sealing strip + middle pressure equalization strip + outer windproof strip between window frame and glass, air tightness reaches national standard level 8.

✅The more locking points the better : at least 5 locking points, with a gap of ≤1mm when tightly closed, to prevent "sound leakage".

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

✅ Wall gaps must be filled : Double-layer filling with high-elasticity foam and weather-resistant sealant, rejecting "perfunctory caulking".

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