This property directly unlocks architectural freedom. The high flexural modulus and strength mean a PET sandwich panel can span much further between supports than a solid aluminum sheet or plywood of equivalent weight. This capability enables clean, minimalist designs: wide-span entrance canopies without visible ribs, large unbroken soffit panels, and streamlined fascias with fewer visible joint lines. It directly allows architects to eliminate secondary steelwork, creating sharper, lighter, and more elegant building lines.
