80 meters and more - the “woodscrapers” are coming
Wood is a wonderfully versatile and potentially sustainable building material which, for good reasons, is now also increasingly being discovered for the construction of apartment block buildings. However, fire protection regulations are still a restriction for high-rise wooden constructions. For example, wooden buildings in Germany which are above a certain height must have escape routes made of non-combustible material such as concrete. In Austria, regulations are similar and as a result, what will soon be the highest wooden house in the world, the HoHo in Vienna, will have a concrete core. We have reported on this previously in our blog. Now, a small town in Norway is about to challenge the HoHo.
“Mjøstårnet” (Mjøsa Tower) is the name of the project that is currently emerging in the Norwegian town of Brumunddal should be for the town what the Eiffel Tower is for Paris. However, while Paris is certainly well-known all over the world, even without the Eiffel Tower, Brumunddal would probably only become widely known because of Mjøstårnet. The 18-floor mixed use building is intended to reach a height of 81 meters – and would thus become the highest timber house in the world.
Really the highest?

As with The Tree, Moelven will also supply and install the various components for Mjøstårnet. The supporting structure of the skeleton construction is made of laminated wood which has a load-bearing capacity of up to 80 percent greater than solid wood. But not only that. The mighty columns and beams additionally have better fire protection qualities than, for example, load-bearing parts made of reinforced concrete. Steel melts at high temperatures and loses its load-bearing capability, while for wood, only the top layer burns initially which has the effect of protecting the rest of the wood from further burning for a long time. If the load-bearing parts are thick enough, as is the case in the Mjøstårnet, the load-bearing capacity remains intact even after a two-hour fire.
