The Profile 70000 – Hidden Sash Series is Signum’s answer to modern minimalist architecture. Engineered for those who appreciate clean, uninterrupted lines and subtle design, this system offers a flush exterior appearance that seamlessly blends into contemporary facades — without compromising on performance, insulation, or durability.
Its compact frame — just 73mm visible width — creates a sleek aesthetic that reduces visual clutter while maximizing the glass surface area. The hidden sash design conceals the opening mechanism behind the outer frame, making it almost indistinguishable from fixed windows when closed, which enhances both style and visual continuity.
Beneath its minimalist exterior, Profile 70000 is a robust performer. Built with a 22mm polyamide thermal break, it achieves a Uf value of 1.7 W/m²K, providing excellent thermal insulation that helps lower energy consumption. It supports glass thicknesses up to 28mm, and is compatible with insulated and laminated glazing options, offering reliable acoustic protection and weather resistance.
Tested under extreme conditions, this profile delivers dependable performance with certified resistance to wind pressure (±5746 Pa / 120 psf), air leakage (0.10 L/s/m²), and water tightness (575 Pa) — making it ideal for both urban environments and storm-prone coastal areas.
