FAQ – Noise Barrier Rental

Here you will find answers to the questions we are asked most often – about products, hire, delivery and performance. Your question is not listed? Then write to us.

Products and performance

What is a mobile noise barrier?

Sound-absorbing acoustic mats that are fixed to temporary fencing or to stable scaffolding. That is the barrier – and after the project it is gone again just as quickly.

What are mobile noise barriers used for?

Wherever it gets loud for a limited time: construction and demolition, road works and civil engineering, core drilling and piling, generators and pumps, industrial plant, events, and night and weekend work. They protect residents, staff and sensitive areas such as hospitals or schools.

How many dB do the systems achieve?

It depends on the system: standard acoustic mats have a sound reduction index of approx. 14–16 dB, high-performance mats 23 dB. How much of this arrives at the neighbour’s depends on frequency, set-up, distance and height of the noise source and on the surroundings. In practice, simple noise screening usually achieves around 10 dB less – most people perceive that as roughly half as loud. Low tones such as bass or humming are attenuated less well than high ones.

Which heights are available?

2.0 m is the standard height of temporary fencing. 3.0 to 6.0 m is usually realised on scaffolding. Special heights on request.

Does it also work for generators, pumps or machines?

Yes, very well. The barriers are suitable for screening diesel generators, hydraulic power units, pumps, compressors and construction equipment of all kinds. Set them up in a U or L shape to enclose the noise source even better.

Are individual solutions possible?

Yes. We also offer made-to-measure acoustic mats, acoustic sheeting for scaffolding and work tents with noise control. Special colours, branding and printed images are possible as well – in some cases for purchase only.

Hire and process

How does hiring work?

1. Clarify the need: length, height, noise source, hire period (from/to). 2. You receive a recommendation and a quote from us. 3. Delivery. 4. Set-up by you. 5. Use during the construction phase. 6. Dismantling and return transport by you. If you need the barriers for longer, a chargeable extension is normally possible by arrangement.

Do you install the systems on site?

Installing the mats is simple – they are fixed with cable ties – and is done by the hirer. For high noise walls on support frames, installation can be offered on request.

How long can I hire noise barriers?

The minimum hire period is 1 week. Typical projects run for 1 to 12 weeks, long-term projects for 6 to 36 months. The longer you hire, the lower the price per month.

What does it cost?

We quote individually. The price depends on the length in metres, the height, the sound reduction index (14, 16 or 23 dB) and fire protection class, the hire period, the delivery location and whether express delivery is needed.

Can I call at short notice if the authority demands more noise control?

Yes. Many customers order exactly when residents complain, the authority threatens to stop the works, night work has been approved or limits are exceeded. Express delivery is possible.

Delivery and set-up

How fast do you deliver?

Within Germany usually within one week as general cargo. For urgent sites, express delivery within 24 hours is possible. It is even faster if you collect the mats yourself from us in Darmstadt. Delivery times to other countries on request.

How are the barriers transported?

By pallet shipment, by lorry or with our own van. You can also collect the mats from us in Darmstadt and return them there free of charge.

Where do you deliver?

To Germany, Austria, Switzerland, Luxembourg, the Netherlands and Denmark; other European countries on request. For Switzerland, rental is only possible if you handle customs clearance and VAT yourself. Delivery times outside Germany are agreed for each project.

What has to be available on site?

Level ground, enough space, access for the delivery vehicle and, if necessary, ballast or bracing against wind. Important: the customer is responsible for a stable set-up.

How much space do I need?

As a rule 0.5 to 1.2 m depth depending on the system, more with scaffolding; where applicable additional distance from danger zones such as tracks; room for ballast or supports; and access for lorries and pallets.

Good to know

How can the sound insulation be increased further?

For example by using the mats in two layers – ideally with a gap between them – or by combining them with closed timber hoardings. You can try the effect of a second parallel barrier in our noise barrier calculator.

Can I buy instead of hiring?

For projects lasting a year or more, buying can make sense. Ask us for a quote for both options.
