Structural glazing Spider: modern façade nuances
Frameless point-fixed façades with floating-glass effect. Tech, loads, real SPb costs.
Structural glazing Spider — premium façade tech: glass anchors via 4 points per panel, no vertical/horizontal profiles. "Floating glass" effect — the building reads as a monolithic crystal.
01Build
Each panel has 4 corner through-holes. A spider (steel "spider" with 2 or 4 arms) anchors through the holes to a steel substructure. Silicone joint 8–12 mm between panels.

Spider is premium and its price reflects that. Tight budget but similar look? Consider very thin mullion-transom (40×40 mm profiles) — looks similar from a distance, 2–3× cheaper.
Real SPb projects: BC Gaiot 2 800 m² (2023, 38M ₽), Galereya atrium 1 200 m² (2022), Sky Garden 4 500 m² (2025).
