Living next to a busy road, train line, airport or lively commercial area can be exciting—but the constant noise is not. Traffic, horns, aircraft, loud music and construction sounds make it harder to sleep, relax, work or study.
Most people first think about acoustic glass when they want to quieten a home. But there’s another powerful tool you can add to the mix: low e glass types. While they’re best known for cutting energy bills and improving thermal comfort, the right low-E configuration can also play an important role in making noise-exposed homes more peaceful and liveable.
In this guide, we’ll break down what benefits low e glass types bring to noise-exposed homes, how they work together with laminated and acoustic glazing, and how to choose the right setup for your project.
1. Quick Refresher: What Are Low E Glass Types?
Low-E (low emissivity) glass is regular glass with a microscopic metallic coating on one surface. This coating is nearly invisible but dramatically improves how the window handles heat:
- In winter, it reflects indoor heat back into the room.
- In summer, it reflects outdoor heat away, limiting solar gain.
- All year, it can block a large portion of UV radiation, protecting interiors from fading.
There are several low e glass types, including:
- Hard-coat low-E – durable, often used in colder climates where some solar gain is desirable.
- Soft-coat low-E – more advanced, often with multi-layer coatings; excellent for strong solar control and high energy performance.
- Laminated low-E – where the low-E glass is combined with a laminated pane for safety, security and better noise control.
On their own, low-E coatings are about thermal performance. But in real-world window systems—double or triple glazing, multiple pane thicknesses and laminated layers—they become part of a high-performance acoustic and energy solution.
2. How Noise Gets Into a Home Through Windows
To understand how low e glass types can help, it’s useful to see how noise actually enters a home:
- Airborne transmission through the glass
– Sound waves vibrate the glass pane, which then vibrates the indoor air. - Air gaps and poor seals
– Even the best glass will fail if noise can leak through gaps in frames, sashes or opening joints. - Resonance and matching pane thickness
– If multiple panes of glass have the same thickness, certain frequencies can resonate and pass through more easily. - Lightweight frames
– Thin or poorly designed frames can act like drums, transmitting sound.
Low-E coatings don’t directly “absorb” sound, but they are nearly always used within insulated glass units (IGUs) that have multiple panes, gas fills, better seals and sometimes laminated layers. All of those elements together improve both sound and heat control.
3. Core Benefits of Low E Glass Types in Noise-Exposed Homes
3.1 A Quieter Home Through Better Window Systems
When homeowners upgrade from single clear glass to double-glazed low-E units, they often report that the house feels:
- Quieter
- More solid
- Less affected by street noise
That’s because high-performance low-E units typically include:
- Two panes of glass with an air or argon-filled cavity
- Different pane thicknesses, which reduces resonance
- Better gasket systems and frames, since the whole window is designed as a performance system
The low-E coating isn’t the acoustic hero by itself, but it’s part of the same engineering package that tackles noise effectively.
3.2 Combining Low E With Laminated Glass for Extra Noise Reduction
For homes exposed to heavy traffic, airports or rail lines, simple double glazing may not be enough. Here, the best approach is to specify laminated low-E glass:
- The laminated interlayer (often PVB) helps absorb and dampen sound vibrations.
- The low-E coating keeps heat under control and blocks UV.
Together, they deliver:
- Noticeably quieter interiors
- Stable temperatures near windows
- Safer glazing that holds together on impact
If you’re comparing where lamination becomes a safety requirement (skylights, barriers, storm zones), it’s worth reading:
👉 Which Safety Needs Require Laminated Low E Glass Types?
Even when codes don’t strictly require lamination, noise-exposed homes often benefit significantly from combining laminate and low-E.
3.3 Thermal Comfort and Acoustic Comfort Work Together
Noise isn’t the only comfort issue near busy roads. These homes are often:
- Hotter in summer (due to direct sun and reflected heat)
- Colder in winter near windows
- Prone to condensation and drafts
Low e glass types address these issues by stabilising the indoor temperature:
- Less heat leakage in winter means you can keep windows closed more often without feeling cold.
- Reduced solar gain in summer makes it easier to keep windows closed and still stay cool.
Since open windows are one of the biggest noise paths, the ability to keep them closed while still feeling comfortable is a huge indirect noise benefit.
3.4 UV and Glare Control for Calm Interiors
Noise-exposed homes often sit in dense or highly built-up areas with lots of reflected light. Low-E glass can help:
- Cut glare while still letting in natural daylight.
- Block UV, protecting soft furnishings, timber floors and artwork.
The overall effect is a more calm, visually comfortable interior, which makes noise feel less overwhelming even when some sound still gets through.
4. Best Low E Glass Types for Different Noise-Exposed Situations
4.1 Homes on Busy Urban Streets
Need: strong reduction of traffic noise, improved comfort, better security.
Good configuration:
- Double or triple glazing
- One pane laminated low-E
- One pane of different thickness to break up resonant frequencies
- Well-sealed, thermally broken frames
Result:
A quieter, more energy-efficient home that feels insulated from the city outside.
4.2 Apartments Near Rail Lines or Airports
Need: maximum noise reduction at both high and low frequencies.
Good configuration:
- Laminated low-E with an acoustic interlayer on the interior side
- A thicker outer pane, possibly with additional solar control
- Deep, well-insulated frames and attention to junction detailing
Here, the acoustic lamination does much of the heavy sound work, while the low-E ensures the glazing doesn’t become a thermal weak point.
4.3 Suburban Homes Exposed to Occasional Noise
Need: more comfort and moderate noise reduction.
Good configuration:
- Standard double-glazed low e glass types with argon fill
- Optional lamination on critical facades (e.g., bedrooms facing a road)
In many suburbs, simply switching from single clear glass to well-designed low-E double glazing reduces noise enough to make a noticeable difference, while dramatically improving energy performance.
5. Noise Control for Skylights and Roof Glazing
Skylights bring in wonderful top light—but they can also let in:
- Aircraft noise
- Rain and hail sounds
- Heat and glare
For noise-exposed homes, low e glass types for skylights should nearly always be:
- Toughened laminated for safety
- Equipped with a low-E or solar-control coating
- Part of a double- or triple-glazed system
This combination:
- Softens external noise from above
- Keeps spaces below the rooflight cooler and more comfortable
- Maintains safety if the outer pane is damaged

6. Don’t Forget the Bigger Design Context
Windows are only part of the story. Even the best low e glass types work better when the overall design supports noise control and comfort:
- Facade orientation and room layout – place bedrooms away from the noisiest sides where possible.
- External landscaping and walls – trees, earth berms, fences and garden structures all help diffuse or block sound.
- Balconies and overhangs – can act as acoustic shields as well as shading devices.
At a broader scale, thinking about glazing, planting, outdoor surfaces and shading together is an example of integrated landscape architecture and building design. For more on that design mindset, you may enjoy:

7. Practical Tips When Choosing Low E Glass Types for Noise-Exposed Homes
- Identify your noise sources
– Road, rail, aircraft, nightlife, industrial? Each has different dominant frequencies. - Decide how quiet you want the interior to feel
– Background noise vs “library” quiet will require different glazing setups. - Talk in terms of whole window systems, not just glass
– Frame type, seals, installation quality and wall construction all matter. - Ask specifically for laminated low-E where noise is severe
– Especially for bedrooms and living spaces facing the noise. - Combine with smart ventilation
– Trickle vents, mechanical ventilation with heat recovery, or well-sealed openings let you keep windows closed more often without sacrificing fresh air. - Balance performance and budget
– Start with the noisiest rooms and ades; you don’t have to upgrade every window to the same level.
Conclusion: Calm, Comfortable Homes With Smart Low E Glass Types
Noise is one of the hardest problems to fix once a home is built, but the right glazing can make a huge difference. While low-E coatings alone won’t make a house soundproof, low e glass types used in well-designed window systems bring a powerful combination of:
- Quieter interiors through double/laminated units
- Better thermal comfort in both hot and cold seasons
- UV and glare control for calmer spaces
- Lower energy bills and a smaller environmental footprint
And when you team low-E with laminated and acoustic strategies, you can transform noise-exposed homes from stressful to serene—without sacrificing natural light, views or design quality.
