Background

A major new hyperscale data centre in the UK required a carefully designed acoustic solution to manage noise from its cooling and heating systems. These systems were position along the edge of the site, close to areas where noise control and visual presentation are essential. The data centre operator required a barrier to reduce sound travelling past the perimeter of the site, as well as complement the architectural language of the development and provide long term durability. The brief focused on acoustic performance, structural reliability, and a clean, visually appealing finish.

The Challenge

The primary challenge was the height and scale required to achieve effective noise reduction. At 9m high, the barrier had to interrupt the line of sight between mechanical plant and nearby receptors while withstanding wind loads associated with such a tall structure. The location along the side of the building created coordination pressures, as installation had to take place alongside ongoing construction activities. The project demanded precise sequencing, reliable access planning, and materials that could be delivered to support a controlled and efficient build.

An additional consideration was visual, the design needed to soften the industrial character of the plant zone and provide an attractive screen for local viewpoints. Any solution had to balance robust acoustic function with a natural finish that would help integrate the site into its surroundings.

Traditionally, earth bunds have been used where noise reduction and aesthetics are required; however, earth bunds require a large footprint.

The Solution

Jacksons Fencing supplied a continuous 9m high timber reflective acoustic barrier, supported by steel I beams designed to handle structural loads. The acoustic barrier was manufactured to provide consistent reflective performance, helping to reduce both tonal and broadband noise generated by the data centre. With deep V tongue and groove boards, the construction provides noise reduction of up to 28dB, and an anti-climb façade.

The steel I beams form the structural backbone of the barrier. Foundation interfaces and fixings were engineered in accordance with the site’s wind conditions and the barrier was installed as a continuous run that maintained acoustic integrity even where the ground level or building interfaces changed. The natural timber finish delivered a soft, visually appealing frontage.

The completed barrier reduces the spread of noise from the cooling and heating systems to sensitive areas and supports compliance with the project’s planning noise limits. Its height and continuity improve acoustic performance while the timber finish provides a clean and attractive elevation.

The barrier is an effective security fence due to its lack of hand or footholds and conceals services, pipework, and plant, effectively improving both functionality and appearance.

The I beam frame ensures the barrier remains resilient under local wind conditions and offers a long service life with a 25 year guarantee against rot, insect attack, and rust, with minimal maintenance requirements; the barrier does not need any painting, staining, or treating throughout its lifetime.
