02Casement

Classic proportions meet contemporary precision. Our casement window systems draw from the timeless language of steel-frame architecture — the slender profiles, the geometric clarity — while delivering the thermal performance and durability that modern living demands.

Concealed handles integrated into the frame, invisible hinges, hidden drainage. Every technical element withdraws from view, leaving only the purity of design.

Frameless windows"Frameless" does not mean without structure: the frame is there, recessed in the masonry, and the sash hides behind the glass. Inside and out, only glass and view remain.
