The Kirchdorfer Group is expanding its product range: the PHONOBLOC® wood-concrete noise barriers, which have been awarded the natureplus® seal of approval, are being fitted with photovoltaic panels. Kirchdorfer is thus opening a new chapter in the greening of Austria’s traffic route infrastructure.

The solar power generated by this product is expected to offset the total amount of energy used to manufacture, transport and install the “noise barrier power plant” after just two years of operation.

With the installation of PV panels (glass-foil) on the upper Y-shaped element, an annual yield of 1,173 kWh/kWp can be expected at a utilization rate of 90%, whereby 1 kWp is equivalent to a generator area of approx. 4.85 m². This corresponds to an annual CO2 saving*) of 325.4 kg/kWp.

In order to make optimum use of the existing noise protection infrastructure, we also make it possible to retrofit existing noise barriers with our power plant noise barrier. With a specially designed Y-shaped element, which is used instead of the uppermost noise barrier element, and an appropriately adjustable substructure, we can optimally align the photovoltaic panels against the sun and at the same time protect them against the wind and snow loads to be expected at the respective location.“ as Klaus Aichholzer, KCS Head of Road Business Unit, explains.

With the installation of PHONOBLOC® wood-concrete noise barriers, the Kirchdorfer Concrete Solutions division is one of the leading providers in the expansion of infrastructure along roads and railways. Thanks to the new development of a Y-shaped element, existing noise barriers can also be retrofitted for the installation of PV panels “on top” by simply replacing the uppermost standard noise barrier element.



Are we a career match?

Do you enjoy sharing your knowledge with others?

Did you know that we use recycled car tires in cement production?

The motto here is ‘Recycling old tires instead of disposing of them.’ In Ohlsdorf, Upper Austria, the only used tire recycling plant in Austria is located. Kias Recycling GmbH, a joint venture between ART and the Kirchdorfer Group, supplies this valuable alternative fuel for our cement plant. This plant is renowned globally for its cleanest cement production.


Do you like to think outside the box?

Do you believe that we manufacture stairs for fish?

Fish ladders assist fish in overcoming barriers such as dams or hydroelectric power plants. The unique Kirchdorfer fish passage system is a clever prefabricated system, much like LEGO blocks. In Austria, it has been used to build the highest fish passage in Europe.


Construction sites and a hammer in hand are totally your thing?

Did you know that we are part of the largest photovoltaic facade system in Austria?

In 2023, our joint venture Martini Beton renovated its office building. The exterior transformation resulted in an integrated PV facade that annually produces environmentally friendly solar power equivalent to the energy consumption of around 50 single-family homes.
