Let Air Pass but Block Noise with Our noise reducing shades
Noise reducing shades resemble ordinary louvers on a building, but they feature a special sound-absorbing inner structure. They fit into wall openings where fresh air is needed without compromising quiet. This solves the common problem of having to choose between sound insulation and airflow-you can have both. They are most effective against medium- and high-pitched noises, such as traffic, fans, or crowds. The slats block rain and dust while absorbing sound. Made from aluminum or steel, they resist weathering and rust, making them ideal for outdoor use.


Tough Design for Outdoor Use with an Attractive Look
These shades are built from strong materials that withstand sun, rain, and harsh weather. The blades are shaped to block water while allowing air to flow freely. Behind the blades, we use sound-absorbing material or perforated liners to trap noise before it passes through. The frame mounts easily into concrete or metal walls and can be painted to match the building color. They are available in different sizes and blade angles. By combining airflow and noise control, they save space and reduce costs, keeping equipment rooms cool without creating noise problems for neighbors.
Where to Use Our noise reducing shades
These shades are suitable for many applications. Power plants, substations, and pump rooms use them on exterior walls to allow ventilation for generators and pumps while keeping noise inside. Apartment buildings near busy roads install them on windows for quiet ventilation. Hospitals and schools use them to provide fresh air without street noise. Highway sound barriers sometimes include them for airflow, and even recording studios or TV stations use them for silent cooling. Standard specifications are listed below.
