The Noise reducer is an effective sound wall with high noise insulation and absorption properties.

The sandwich construction includes:

  • A layer of noise absorbent mineral wool.
  • A thin metal plate for extra noise insulation.
  • All encased in a steel U-profile frame with galvanized steel wire-netting surround and high-density polyethylene (HDPE) windshield.

The Noise reducer HA is an extremely effective sound wall with very high noise insulation and absorption properties. The solid construction means the panels can be stacked on top of each other to heights up to 6 m.

The sandwich construction includes:

  • A layer of noise absorbent mineral wool.
  • A thin metal plate in the centre for extra noise insulation.
  • All encased in a steel U-profile frame with a galvanized steel wire-net (front and back) and HDPE windshield.

The plant-friendly surfaces of the panels can easily be covered with climbing plants or other decorative vegetation for natural blending into most surroundings.

Features and benefits:

  • Effective noise insulation and absorption.
  • Suitable as perimeter and sight protection.
  • Lightweight with a small footprint for easy installation.
  • Satisfies the most stringent noise reduction directives.
  • The surface is suitable for climbing plants (not HA model).

Applications:

With their lightweight, small footprint and easily installed pre-fabricated format, the barriers are suitable for busy roads, school playgrounds, and surrounding loud installations such as air conditioning units or transformers.
