The paper is dealing with the development of thin slabs made from white Ultra-High Performance Concrete (UHPC), which can be used as facade or roof panels. The slabs were designed with reinforcement realized by randomly dispersed polyvinylalcohol (PVA) fibres and a textile glass 2D net with mesh 20 x 20 mm. The used 2D reinforcement (AR - Glass with 2400 TEX fineness) was coated to became resistant to alkaline environment. Three slab specimens with size of 750 x 125 x 15 mm were prepared and tested in four-point bending. The courses of the tests were continually monitored by an automatic measuring unit. The acting force, the deformation in the middle of the span, the deformation in the supports and the progressive formation and development of cracks were detected. The numeric model was created in 3D surroundings of Gid 2011 program and then converted into ATENA software. There was found an efficient correspondence between the results of the numerical analysis and the experimental tests.
