When laying boards on joists, it it is important that the floor is even, without significant differences in level. Loose Fill is ideally suited for this purpose. In addition, make sure that the AGEPAN® OSB Ecoboard® is butted onto the beam. If the preliminary planning allows it, it is recommended to adjust the distance between the beams to the format of the AGEPAN® OSB Ecoboard® in order to avoid waste.
