The longevity of wooden houses: How long can they last?
Just like traditional construction homes, prefabricated wooden houses also require regular maintenance or renovation of individual elements. There is no significant difference in the maintenance of a traditionally constructed house or a prefabricated wooden house.
Since the assembly of the prefabricated house elements takes place in the factory under controlled conditions, this also reduces the possibility of errors during the construction itself.
Are Jelovica wooden houses earthquake-resistant?
Yes, Jelovica prefabricated wooden houses are designed to be earthquake-resistant. The wooden frame structure transfers vertical loads, while the horizontal load, including earthquakes, is carried through cladding plates attached to the load-bearing structure. Proper design of the frame and panel claddings ensures the seismic resistance of the prefabricated houses. Wood, thanks to its greater elasticity, responds better to ground shaking compared to materials like concrete or brick. Additionally, prefabricated wooden houses are lighter than masonry homes, which reduces the horizontal force during an earthquake. Jelovica wooden houses are designed to withstand earthquakes and are used worldwide for their lightness and flexibility in seismic movements.
