Heat-treated wood protects big moose

Published: 27 July 2015

Stoorn, a 45 meter high wooden moose on the top of the mountain Vithatten, that is the entrepreneur Thorbjorn Holmlund's dream which he hopes to realize. If the construction of Stoorn begins, the University's knowledge of heat-treated wood will be an important part of the design.

– Heat treated wood has a greater resistance than ordinary wood, and that it is important because the moose will be exposed to extreme climatic variations in the form of sun, rain and cold winters. The heat treatment also makes it possible to obtain a surface that resembles the fur of a live moose, says Tom Morén, Professor emeritus in Wood Technology at Luleå University of Technology.

Luleå University of Technology in Skellefteå has a world unique equipment that makes it possible to analyze and perform heat treatment of wood, namely a CT-scanner combined with a custom build environmental chamber.

– The equipment allows us to analyze the material wood and the entire heat treatment process in a way that in fact cannot be done anywhere else. Heat treatment opens possibilities for wood as a building material, and another plus is that it is an environmentally friendly method, says Tom Morén.
