Choose the opening action before the window system.
Casement, fixed and tilt-turn windows have different size limits, hardware and safety requirements even within the same profile house. Approved drawings and the quotation govern the fabricated order.

Repeated openings need repeatable workshop checks.
Window schedules can use agreed opening references, with the labelling requirement stated on the quotation.
Profile-system options
