PROCURAL PE78NHI Window Curtain Wall

Window system with facade appearance for large-scale constructions

PROCURAL PE78NHI Window Curtain Wall is a three-chamber profile system with excellent insulation properties, adapted for a wide range of window hardware. A 42 mm thermal break and dual-component center seals provide high thermal insulation. The profile reinforcement shape imitates curtain wall mullions, creating an integrated facade appearance. The three-chamber design gives profiles high rigidity, allowing the creation of large-scale constructions. Two system variants are available depending on the inserts used — PE78N+ and PE78NHI. The system supports fixed windows, tilt-turn, outward-opening, and concealed hinge constructions.
