There are webs or panels of mineral wool, in particular rockwool, for heat and/or sound insulation of buildings, in particular building roofs and external walls, in which the mineral wool is always formed within the web or panel from successive, mutually overlapping layers and in which the mineral fibres are ordered essentially parallel to the layer surfaces. In order to create a web or panel of mineral wool which, on the one hand, has a sufficient compressive strength in the direction perpendicular to the surface of the web or panel but, on the other hand, at the same time has a high degree of elasticity at least in one direction running parallel to the surface of the web or panel, with likewise sufficient compressive strength, it is proposed that the layers are provided to extend at an angle of about 10 DEG to 60 DEG , preferably 15 DEG to 45 DEG , relative to the plane of the web or panel.
