Résumé

Timber construction has become more and more competitive by adapting efficient prefabricated construction methods and by recent changes in fire protection norms. Until recently, multy-story buildings had to contain an escape route built in non-combustible materials. Nowadays, the fire protection rules veer towards performance-oriented criteria, as seen recently with the changes of Swiss fire protection specifications. However, cladding of the structure is still necessary in most cases and it is usually necessary to fill voids of the structure with non-structural materials, such as mineral wools etc. Massive structures that incorporate the fire cladding functions and add to thermal inertia while still retaining some degree of insulation and can, due to their low weight, be easily integrated into the prefabricated timber-construction process could have a big potential in timber construction.
