Have you ever tried relaxing at home, only to hear traffic, construction or loud neighbourhood sounds right through your windows? Many of our clients come to us with the same concern. Noise affects sleep, focus and overall comfort, which is why choosing the right glazing system is so important. The question we hear most often is simple: Which window reduces noise better—regular glass, DGU or TGU?
Here’s the answer based on our experience as façade and glazing specialists.
Why the Right Window System Makes All the Difference
Windows are the biggest pathway for noise to enter a building. Even a strong wall cannot compensate for poor glazing. That’s why, in our projects, we always guide clients toward window systems that offer both structural strength and acoustic performance. Modern glazing technologies like DGU and TGU reduce noise by slowing down vibrations before they enter your space.
Regular Glass: Basic but Not Built for Noise Control
Regular single-pane glass offers minimal insulation against noise. Since it has only one layer, sound waves travel through it without much resistance. If your building is located near a busy road, a metro line or a crowded commercial area, regular glass simply won’t provide comfort.
We install regular glass only in low-noise areas or internal partitions—not for exterior windows that require acoustic performance.
DGU Windows: The Practical and Popular Noise Reduction Solution
DGU windows—also known as Double Glazed Units—have two panes of glass separated by an insulating air or gas gap. This extra layer dramatically cuts down external noise.
Why Our Clients Choose DGU for Noise Reduction
- The two glass layers create a stronger protective barrier
- The gap between them slows down sound vibrations
- Laminated glass can be added for even better results
- Cost-effective compared to TGU
- Ideal for medium to high noise levels
For most residential and commercial projects, DGU windows offer more than enough sound insulation and also improve thermal performance.
TGU Windows: The Highest Level of Acoustic Comfort
TGU, or Triple Glazed Units, provide the strongest noise reduction available today. With three glass panes and two insulating cavities, they create a powerful shield against heavy noise.
Where We Recommend TGU
- Apartments near airports or railway lines
- Buildings close to industrial zones
- Premium residences seeking maximum silence
- Hotels, hospitals and corporate offices where quietness is essential
TGU windows cost more but deliver unmatched peace and comfort, especially in high-noise environments.
DGU vs TGU: Which Works Best for Your Space?
As façade experts, we always begin with a site assessment. The right glazing depends on the level of noise around your property.
Go for DGU if you:
- Want solid noise control for everyday disturbances
- Live near moderate traffic
- Prefer a cost-efficient option
- Want improved insulation without adding too much weight
Choose TGU if you:
- Face constant, heavy noise
- Live near highways, airports or railways
- Need premium acoustic performance
- Want the most advanced soundproof window system
Both are excellent choices—your environment helps decide the perfect fit.
Why Laminated Glass Is a Game-Changer
We often recommend combining laminated glass with DGU or TGU systems. The interlayer inside laminated glass absorbs sound frequencies extremely well. This combination is ideal for clients who want superior noise reduction without changing the entire window system.
Buildings like hotels, offices, schools and luxury apartments benefit the most from this upgrade.
Our Recommendation: What Works Best Overall?
To put it simply:
- Regular Glass → Not suitable for noise control
- DGU Windows → Best choice for most homes and offices
- TGU Windows → Best for high-noise locations and premium comfort
Most of our customers choose DGU because it offers strong acoustic and thermal insulation without a steep cost increase. For extreme noise levels, TGU remains the top-tier solution.
Final Thoughts
A peaceful environment starts with the right window system. Whether you prefer DGU or TGU, upgrading to an insulated glazing unit is the most effective way to reduce noise and improve comfort. As a façade solutions company, we ensure every window is engineered, installed and sealed to deliver long-lasting performance.
