Swiss Spruce, Western Size, Grade III, moderately thermo-treated
Producer: Florinett, Graubünden, Switzerland
FSC-certified operation, both forest and mill
Advantages of thermo-treated wood against conventional timber:
* higher velocity of sound in all directions
* lower density means reduced weight
* reduced resorption capacity leading to lower shrinkage and swelling and higher dimensional stability
* fully dry after heat treatment, wood can be processed immediately
