Soundproof Windows
Tired of street noise, neighbors or construction? Windows with Silent Package technology reduce noise levels 1.5 times more effectively than standard windows. Finally, peaceful sleep and quiet in your home.
Who Needs Soundproof Windows?
Silence is not a luxury, it's a necessity
- Windows facing a busy street — trams, buses and trucks will no longer disturb your sleep.
- Construction or industrial sites nearby — protection from constant background noise.
- Noisy neighbors or kindergarten below — enjoy silence at any time.
- Working from home — concentrate without distractions from street noise.
- Sensitive sleep — fall asleep quickly and sleep soundly.
Silent Package Technology
Street noise enters the room through windows. Silent Package uses glass of different thicknesses and chambers of different widths filled with argon. This combination dampens sound vibrations of different frequencies, providing noise reduction up to 50 dB.

Impact of Noise on Health
Why silence is so important
Effects on Adults
Research shows that constant noise exposure leads to serious health problems:
- High blood pressure — the body reacts to noise as stress
- Cardiovascular diseases — chronic noise increases heart attack risk
- Sleep disorders — even if you don't wake up, noise reduces rest quality
- Increased anxiety — constant noise background exhausts the nervous system
Effects on Children
Children are particularly vulnerable to noise. Constant noise background can cause:
- Memory impairment — noise interferes with concentration and memorization
- Reduced attention — harder for child to focus on studies
- Reading problems — noise hinders speech skill development
- Chronic fatigue — poor sleep quality affects development
Glazing Type Comparison

| Single chamber unit | 4-4 mm | ~25 dB | Only for quiet areas |
| Double chamber standard | 4-4-4 mm | ~30 dB | Basic option |
| Double chamber with argon | 4-4-4 mm | ~35 dB | Good choice for city |
| Silent Package (different thickness) | 4-6-8 mm | ~45 dB | Recommended for busy streets |
| Acoustic triplex | 6.5-12.8 mm | up to 50 dB | Maximum protection |
* Acoustic glass consists of two laminated glass layers with PVB film between them. This film absorbs sound vibrations, providing maximum soundproofing.

Additional Soundproofing Factors
Increased Width Profile
For maximum soundproofing, we recommend profiles 70 mm wide and more. 70-88 mm profiles have 5-7 air chambers, each serving as an additional sound barrier.
Thermal Insulation as Bonus
Thick acoustic glass retains heat well. Heat transfer coefficient (U-value) around 1.2 W/m²K — this means less heat loss in winter and coolness in summer. Soundproof windows pay for themselves through heating and air conditioning savings.
Sandwich Panel Reveals
Noise penetrates not only through glass but also through reveals and installation joints. 10 mm thick sandwich panels additionally absorb sound and insulate the reveal. We include this finish in standard installation.
Professional Installation
Even the best glass unit won't protect from noise with improper installation. Our installers follow standards and use quality installation materials for complete sealing.

FAQ
Frequently Asked Questions About Soundproof Windows
How does Silent Package reduce noise?
Silent Package uses glass of different thicknesses and chambers of different widths filled with argon. This combination dampens vibrations of different frequencies, so Silent Package reduces noise up to 50 dB and is approximately 1.5 times more effective than standard glass units.
How much more expensive are soundproof windows than regular ones?
The price difference is 15-25% depending on configuration. You get not only silence but also improved thermal insulation, which pays for itself through heating savings.
Which profile is best for soundproofing?
We recommend profiles 70 mm wide and more: REHAU Synego (80 mm), REHAU Geneo (86 mm), Schüco Living 82, Kömmerling 76. More chambers and profile depth = better noise protection.
Can soundproofing be installed on existing windows?
No, for maximum effect complete window replacement is required. The glass unit must be specially designed considering glass thickness and chamber width. Proper installation is also important.
What is acoustic glass and how does it differ from regular glass?
Acoustic glass is laminated glass consisting of two layers with PVB film between them. This film absorbs sound waves and vibrations. Acoustic glass thickness from 6.5 to 12.8 mm allows achieving soundproofing up to 50 dB — twice as much as a regular single chamber unit (25 dB).
Does reveal finish affect soundproofing?
Yes, significantly. 10 mm thick sandwich panels additionally absorb noise, insulate the reveal and block sound penetration paths through reveals and installation joints.
