Steel-skin entry tier
RD67
RD67 is the sensible starting point when the goal is Ryterna fit, finish and design control without paying for the deeper aluminium systems. Its cold-rolled steel skins are galvanized, treated and powder coated. The frame uses a 24mm thermal break, and the standard hardware package is already a proper three-point lock with a WILKA cylinder and five keys.
- 67mm double steel-skin leaf
- 0.94 W/m²K on the published test size
