¹OS represents ordinary sandwich panels (PU core) without lattice-web reinforcements, and the following number (e.g., 50, 75, and 100) represents the height of the core. ²TS represents lattice-web reinforced sandwich panels; the first number (e.g., 75, 125, and 175) represents the spacing between the lattice webs, and the following number (e.g., 50, 75, and 100) represents the web height.
