Ancient craftsmanship meets modern technology - strong & durable
Log construction has survived for so long because of the many positives attributes associated with both the design and the materials.Timber buildings are known for very good stability and strength, and the material is 100% renewable, something that fits well with today’s discussions on the future and the environment.
In terms of the abrasion resistance, log constructions are proven to be very stable in areas where the weather and the forces of nature are harsh. They have excellent durability even in the face of earthquakes, hurricanes and typhoons, or major strains due to snow masses. It is often said that log constructions resist both vertical and horizontal movement in a way that many other buildings can’t handle. This is a factor of buildings’ design and composition, as well as of the quality of the wood.
And the Nordic pine used in manufacturing Hasseltornet models is particularly durable. This durability is thanks to the wood’s slow growth in clean and healthy forests. An important bonus with this timber is that it holds a high concentration of wood fibers, which makes it very fire resistant. When the surface layer is charred, the inside of the log becomes insulated, retaining its structure and holding its capacity for resistance for a long time.
Massive logs from 200 mm and up reach as high as EI90 in fire rating, which is an excellent score. The thickness also ensures the building meets Swedish energy requirements for permanent housing throughout Sweden’s zones.
