Perforated Aluminum Balcony Screens and Noise on Busy Streets

t260-33

Perforated aluminum balcony screens can reduce some street noise by partly blocking and scattering sound before it reaches the balcony and nearby openings. They work best as part of a combined approach with solid barriers, sealed windows and careful design, and they still provide visibility and airflow.

How perforated aluminum screens affect sound

Sound travels in waves, and a solid panel reflects much of it. A perforated aluminum screen behaves differently: the holes let some sound pass through, while the metal surface and the pattern of perforations break up and scatter the waves. The result is usually a modest reduction in the noise that reaches your balcony, rather than complete silence.

The effect depends on how much of the surface is open, the size and spacing of the holes, and the distance between the screen and the noise source. Traffic noise is often low-frequency and hard to block, so expectations should stay realistic.

Where screens help most on a busy street

Screens are most useful when they sit between the balcony and the direction of the traffic. Their effect is limited when noise arrives from several directions or from above. A well-placed screen can also soften the sound of nearby engines and horns that hit the balcony at a low angle.

Balconies facing a main road or intersection
Ground-floor and lower-floor balconies near passing vehicles
Spaces where you want to keep the balcony usable during daytime

Combining screens with security bars

Many residents want protection and quiet together. A perforated aluminum panel can sit within a security frame so the balcony stays safe from unwanted entry while sound is softened. Planning both at the same time keeps the design consistent and avoids cutting or reworking the structure later.

Aluminum is light, does not rust easily, and suits the coastal environment of Tel Aviv. The panel and frame should be matched in finish so the result looks intentional rather than added on.

Design choices that matter

Several details change how well a screen performs and how it looks from both sides:

Perforation pattern and open area, balanced against privacy
Panel height and how fully it covers the balcony edge
Gaps at the floor and at the sides, which can leak sound
Fixing method, so vibrations are not transmitted into the wall

Your engineer or our team can review these with you on site.

Balancing noise, light, air and privacy

A screen that blocks too much can make a balcony dark and stuffy, while one that is too open may not help with noise. Perforated aluminum offers a middle path: some daylight and airflow, partial privacy, and a noticeable softening of sound. Consider which direction you sit facing most of the day and how much light your rooms need.

Think about how you will use the space, whether for plants, seating, or children playing, and choose the density accordingly.

Planning the project step by step

A clear process helps avoid surprises. Start by sending photos of the balcony and the street side. We then measure on site and prepare a drawing and written specification for your approval. Once approved, the panels and frame are produced in our factory and finished with hot-dip galvanizing or powder coating, before installation.

For railing heights and safety requirements, we follow the Israeli railing standard SI 1142 and confirm exact values with the engineer for your building.

Frequently asked questions

Will a perforated aluminum screen block all street noise?

No. It reduces some of the noise reaching the balcony, especially higher-frequency sounds, but it will not make the space silent. Results improve when combined with sealed windows and other measures.

Does a perforated screen reduce light and airflow too much?

It keeps a good amount of daylight and air moving through the holes. The open area can be chosen to suit your balance between privacy, light and sound reduction.

Can the screen be combined with security bars?

Yes. Many projects integrate a perforated panel into a security frame so the balcony is protected and quieter at the same time.

Do I need an engineer for this kind of installation?

For railing heights and fixing details, it is advisable to confirm with the engineer for your building. We can coordinate the drawing and specification with them.

Common mistakes to avoid

Choosing a screen only for appearance without considering the direction of the traffic and the size of the gaps. Ignoring side and floor openings, which can let much of the sound through.

Our recommendation

Measure the balcony and note the direction of the main noise source before choosing the perforation density. Plan the screen and security frame together so the fixing and finish match.

Summary

Perforated aluminum balcony screens can soften street noise while keeping light, air and security. Their effect is real but moderate, so plan them carefully and combine them with other measures.
