Konstruktionsvollholz (KVH) wird aus Fichte, Tanne, Kiefer, Lärche und Douglasie hergestellt und nach Tragfähigkeit, Holzfeuchte, Einschnittart und Maßhaltigkeit sortiert. KVH gehört zur Kategorie Bauschnittholz, dabei handelt es sich allerdings um ein veredeltes hochwertigeres Produkt, dessen Feuchtegehalt 15 % nicht überschreiten darf. Als Vollholz werden Erzeugnisse bezeichnet, deren Querschnitte aus einem Baumstamm gearbeitet und eventuell spanabhebend weiterverarbeitet wurden. Im Gegensatz zu Brettschichtholz und Holzwerkstoffen wird das Gefüge nicht mechanisch bzw. mechanisch-chemisch verändert.
Konstruktionsholz kaufen dadurch sollen nachträgliche Verformungen an Bauwerken – durch das Austrocknen des Holzes – minimiert werden. Diese Reduktion wird durch eine künstliche Trocknung (Kammertrocknung) erreicht.

Deputies, Men of the German Reichstag! A year of events of historical significance is drawing to an end. A year of the greatest decisions lies ahead. In these serious times, I speak to you, Deputies of the German Reichstag, as to the representatives of the German nation. Beyond and above that, the whole German people should take note of this glance into the past, as well as of the coming decisions the present and future impose upon us. Today, we have overwhelming and authentic proof that Russia intended to attack; we are also quite clear about the date on which the attack was to take place. In view of the great danger, the proportions of which we realise perhaps only today to the fullest extent, I can only thank God that He enlightened me at the proper time and that He gave me the strength to do what had to be done! Our enemies must not deceive themselves-in the 2,000 years of German history known to us, our people have never been more united than today. The Lord of the Universe has treated us so well in the past years that we bow in gratitude to a providence which has allowed us to be members of such a great nation. We thank Him that we also can be entered with honour into the ever-lasting book of German history!
