A 3D cutaway diagram of a rectangular wall element showing layers: OSB base (1.2 cm), OSB side walls (12 cm), XPS insulation, and Fermacell board (1 cm) on top, with dimensions.

Technical 3D cutaway illustration of a rectangular wall element ("tray") construction, shown in perspective. Outer dimensions: height 190 cm, width 75 cm, total depth approximately 14.2 cm. Construction layers from back to front: 1. OSB base panel, 1.2 cm thick. 2. OSB side walls forming an internal tray, 12 cm high, running along the edges of the base plate (interior walls, flush with the base edges). 3. XPS insulation filling the tray completely inside the OSB walls. 4. Fermacell board, 1 cm thick, fully covering the top surface, including the OSB walls, flush with the outer edges. Perspective view, slightly angled to show layers clearly. Realistic textures: OSB wood texture for base and walls, blue foam for XPS insulation, light gray for Fermacell. Neutral white background. Technical, clean illustration style. No people or artistic effects. See more
