Glass floors: structure, load, 2026 price
Laminated under the floor is engineering, not decoration. Substructure requirements, typical-span prices, real cases.
A glass floor isn't "buy a panel and lay it." It's a 3–4 layer PVB-laminated glass package on a steel frame with anti-slip coating, engineered to SP code for the specific span and load.

Most common complaint after 2 years: "scratches appeared." Normal. Anti-slip sandblast has texture that collects dust and shoe grit. Prevention: weekly soft-brush cleaning.
