CLT Production.jpg

The temporary end to major investments

Article by Günther Jauk (translated by Eva Guzely) | 27.11.2023 - 12:26

Basically in contradiction to the poor sales situation, CLT production will continue to grow in 2023, albeit at a significantly lower rate than in previous years. The figures reported by manufacturers from the DACH region, Italy and the Czech Republic show an increase of 4% to 1.27 million m³ and thus another production record.

Given the current market situation, this development is atypical at first glance. It is mainly due to newcomers or fairly new market participants whose capacities are far from being fully utilized. In 2023 alone, five new production facilities will be launched by best wood Schneider, Mayr-Melnhof Holz, Mosser Leimholz, Schilliger and Ziegler Holztechnik.

Major projects in the DACH region

Mayr-Melnhof Holz is carrying out the biggest investment project in the company’s history at its headquarters in Leoben. There, the group is building a cross-laminated timber plant with an annual capacity of 140,000 m³. Together with its CLT production site in Gaishorn am See, the Styrian company’s total capacity amounts to well over 200,000 m³ a year.

best wood Schneider is starting up a cross-laminated timber line with an annual capacity of 100,000 m³ next to a sawmill at its newly built production site in Meßkirch/DE. At its headquarters in Eberhardzell, the company already produces an annual 25,000 m³ of CLT with a width of 1.25 m. For the production of the same system format, Mosser Leimholz recently put a production line into operation in Randegg.

In Hermsdorf, at the former Tecsol factory, Ziegler concentrates and expands its glued timber competencies. Even though the site was originally designed almost exclusively for glulam, a CLT line was put into operation there a few months ago. In the future, Ziegler wants to process around two thirds of its production output into finished modules, while one third is to be sold. In 2021, the company had also announced a major project in Tirschenreuth, Bavaria, which includes two CLT lines, each with an annual capacity of 75,000 m³, as well as a house construction line for up to 3,000 houses a year. At the moment, Ziegler is waiting for the development plan to be approved. Only then, the detailed planning can start and the expected start of production can be determined. At the same time, the company will closely monitor the market and, if necessary, react to it and make adjustments.

In addition to its production facility in Küssnacht/CH, the Swiss timber group Schilliger is currently building a second CLT plant at its French site in Volgelsheim, directly at the German border. Regular production is scheduled to start at the beginning of 2024.

Another jump in capacity

According to the machine suppliers, there are still some Central European companies who plan to increase their capacities, but most of those plans have been put on hold for the time being. In light of the current economic situation and the existing capacities, this is not surprising. When you add up the possible output of the existing plants and the plants which are under construction, you get around 2.3 million m³ a year which will be available in the coming years (see below).

However, experience has shown that even in times of a buoyant economy, it takes several years for a company to build up the necessary structures – from planning to production and sales – to be able to come close to fully utilizing their theoretical capacities. Once Cltech’s planned production site in Kaiserslautern has gone into operation sometime next year, the times of huge investment projects will probably be over for quite a while.
