MX 603 — Minimal casement
Minimal thermal-break casement: slim profiles, strong performance and coordinated design options, including an “iron-look” sash.
MX 603 is a thermal-break casement with reduced profile sizes. It uses 28 mm New Lambda insulating bars. Declared sightlines are 70 mm at the side node and 94 mm at the centre node. Sash design options are square, chamfered or “iron look”. Suited to new build and renovation, including smaller openings, with higher light transmittance versus traditional systems (indicatively +18–24% depending on typology).
