How do polycarbonate observation domes ensure unobstructed 360° visibility?

To deliver uninterrupted 360° visibility, our observation domes employ an innovative combination of structural design and material selection. Above a strategic sight-line, we transition from framed panels to large, curved multiwall polycarbonate sheets that span between minimalistic slim aluminum ribs—just 50 mm wide—reducing visual obstruction. These ribs follow a geodesic pattern, positioning joints outside typical eye level. Seams between panels use low-profile EPDM gaskets and concealed pressure plates, ensuring watertight performance without bulky hardware. The transition to the base ring includes a transparent acrylic glazing strip, providing a seamless horizon view. Interior lighting fixtures are recessed into the frame or surface-mounted beneath the eye-line, preventing glare on the viewing surface. All mounting hardware is anodized to match the polycarbonate’s transparency, blending into the background. This careful integration of structure and skin guarantees a pure, panoramic experience for observers.
