Bestimmung der Feuerwiderstandsdauer von Fachwerkwänden / Determination of the Fire Resistance Period of Half-timbered Walls

As there are no certificated qualification for the fire resistance period of halftimbered walls different walls with and without claddings were tested. The tests were carried out in a small fire chamber and are based on DIN 4102. On the basis of the tests the dependence of the building elements and materials according tofire were revealed. It was obvious that careful sealings mainly in the area of joints could reduce the passage of fire and thereby the failure of the whole construction. Good sealings are clay and other insulating mortars that are used for infillings. Good sealing materials are further plaster and/or insulating plaster layers just as panel kind materials like gypsum and fire prevention boards. The present results are not able to replace a test according to DIN 4102 Τ 2/3 but they can be helpful for a judgement of an individual expert's opinion.
