Wood as a construction material has taken on greater importance than would have been thought possible just a few years ago. Structural research has brought about major improvements to the fire safety and soundproofing of timber structures, and material developments and computer-assisted calculation and assembly methods are enabling completely new forms of design. Forests cover over 48% of the total area of Austria, and with a share of 60%, spruce is the most common tree and the main construction timber used. CLT is made from PEFC-certified softwood derived from sustainably managed forests and controlled sources. A PEFC certificate guarantees that CLT is produced according to the highest environmental and ethical standards.
