The calculator is 52mm Gulf (slim luxury); use 35mm/40mm sliding for big balcony glass on the same floor.

See slim glass doors when the ground floor needs alignment.
Very high floor without tuned reinforcement — we will flag in structural review.
Hidden steel or thicker profiles carry wind without fat sight lines.
Thicker DGU in slim grids often dictates lifting equipment line items.
Concealed hinges, minimalist handles, and finicky adjustment add skilled labour hours.
Stone and tile interfaces need laser control — “almost flush” is expensive when wrong.
