Shot-Resistant, Break-In-Resistant, Explosion-Resistant Façades
Shot-resistant façades can be achieved using the recipe durcrete ‘shot’. With a slenderness of 7 cm, no piercing or spalling will happen under impact of solid-core ammunition calibre 7.62 x 51 mm (class 7 acc. EN 1063 oder EN 1522/1523). Resistance class RC6 to manual burglary attempts acc. EN 1630. Panels can be delivered from Germany or produced in a local prefab plant. More Infos see www.durcrete.de/downloads/.
Façades with laminated foils
A simple method of relocating sales from downstream trades like plaster, tiles, coatings and claddings toward the precast plant is to coat or laminate the concrete surfaces with special foils. Durcrete and Prilhofer Consulting [www.prilhofer.com] have specialized in this field of added value and are advising prefab plants on this new topic in the whole world. More infos see BFT-international 03/2018.
