Still there are old prejudices when it comes to building with wood. Good reason, therefore, to compare the 10 most common wrong opinions and the right facts:
Error 1: “Wooden houses do not last so long”
Wooden houses are extremely durable when they are well built. The best proof are the centuries-old wooden houses in climatically rough regions such as the Alps and Scandinavia. Probably the oldest wooden house in Europe, which is probably the oldest wooden house in Norway, dates back to 1170. Modern wooden structures also offer an excellent long-term perspective – today the construction of wood preservation is so perfect that the durability of wood is practically unlimited. Wooden houses are thus, in terms of their service life, of other construction methods in nothing.
Mistake 2: “Wooden houses burn lighter”
Wooden houses are subject to the same legal fire protection regulations as houses constructed in a different construction. These regulations are absolutely binding in the planning and realization of buildings. Therefore the fire risk of wooden houses is not higher. By the way – wood keeps its static self-protection longer than many other materials!
Error 3: “Wood is moldy, and if not, it must be done with a lot of chemistry.”
Mold is produced in the case of structural deficiencies or unsuitable constructions, irrespective of whether the house has been built in wood or in another construction. In keeping with the constructive wood protection and the building physics, the mold has no chance in a wooden house. In residential construction, wood is installed today with wood moisture levels of less than 20% and is protected by the construction in a sustainable manner against unacceptable moisture. In order for fungi to develop, however, it would take a lot of wood moisture, which is much higher.
Mistake 4: “Wood always looks like a Schwarzwaldhaus”
Wood look is not a must: Many wooden houses are often not seen their construction. Depending on the owner’s taste, wooden houses can also be plastered or clipped. Many examples of modern architecture show the diversity of design that wood offers – the perfect material for individual building concepts and interesting styles.
Mistake 5: “For the timber the forests are cleared”
The Federal Forest Inventory has shown that there is as much wood in our forests as it has been for centuries – and with a high use. The wood used for timber construction comes from sustainable timber management, which has been operating in Germany for 300 years. So more wood grows than we use. When wood is installed and not fired, it makes a multiple contribution to climate protection: it keeps the bound CO2 in its cell storage as building timber, and this climate-damaging gas is absorbed by newly planted trees.
Error 6: “Hardly anyone builds a wooden house”
It is true: more and more builders in Germany are choosing wood for construction. The current timber construction ratio in residential construction is 16.1%, – and the trend is rising.
Error 7: “There are frequent licensing problems with wooden houses”
The Land Building Regulations lay down the same rules for wooden houses as for other houses. In normal home building, there are therefore no differences in the approval procedure.
Error 8 “Wooden houses are nurturing”
Like so much that we want to maintain in a good state, buildings also need regular maintenance and maintenance. And this is completely independent of whether they have been created in wood construction or in a different construction. A wooden house does not require much more maintenance either inside or outside, and does not incur any higher costs.
Mistake 9: “It takes a long time to build a wooden house”
Wood is a top rider in terms of short construction times! The components are precisely prefabricated industrially, and this part of the construction project is completely independent of weather conditions. On the construction site, the shell is often 1 to 2 days long. For weeks, drying phases such as masonry or concrete are dispensed with. This makes timber construction faster, more accurate and of higher quality than building in a different construction.
Mistake 10: “Wooden houses are more difficult to finance”
In principle, the same prerequisites apply to the financing of timber and other houses – so there are no special “wooden house” conditions. Similarly, wooden buildings are treated equally when it comes to grants from KfW-Bank.
