A new
Edition of Timber Arch

In our new edition of the Timber Arch publication, we present a selection of excellent architectural projects that have been developed thanks to the editorial support of the architectural offices.

The publication contains a special collection of KLH® projects that show the versatility, uniqueness, harmony and beauty of solid wood as a building material. No matter whether it is a cosy single-family house, a modern, environmentally friendly school or an exclusive hotel building - KLH® - CLT makes every project special and inviting.

Cross-laminated timber with its versatile application as well as its lightweight and high degree of prefabrication sets unbeatable trends, providing a high level of freedom in architecture. All this is what makes wood the building material for our sustainable future.

2nd KLH
CLT FACTORY

In 2019 KLH Massivholz Wiesenau GmbH has started building of new cross laminated timber plant in Wolfsberg in Carinthia (Austria). The commissioning of the plant with an annual capacity of around 150,000 m³ in the final expansion stage is planned for mid-2020.

This project is co-financed by the ERDF European Regional Development Fund.
 
 
The latest production technology used in the new plant will safeguard the competitiveness and market share of the Johann Offner Group in the field of cross laminated timber, increase the degree of prefabrication of the cross laminated timber produced and create up to 83 new jobs in the structurally weak Wolfsberg region.
