One handle, two motions. German Salamander profiles, specified for American walls. Tilt for locked ventilation; turn inward to clean, pass furniture, or meet an egress opening.

The motion
The sash leans in at the top a few inches. Bottom keepers stay engaged so you can vent overnight without an open hole at the sill.
The same handle swings the sash fully into the room. Wash both faces of the glass from the floor. Size the opening for egress when the code asks for it.
European multipoint locks throw bolts around the sash. The count rises with the size of the unit — not a single latch at a meeting rail.
Each window is produced on Salamander Streamline 60 or 76 after we spec the wall, glass package, and hardware. No stock sizes.
Salamander systems
Both profiles are German uPVC systems with steel reinforcement and tilt-turn hardware. Cross-sections below are manufacturer technical drawings of the Salamander Streamline systems we import.

Multi-chamber entry system. Compact 60 mm installation depth with glazing up to about 36 mm. Suited to replacements where wall depth is limited.

76 mm installation depth, five chambers, dual seals, and glazing up to about 48 mm. The workhorse for thermal and acoustic performance with full tilt-and-turn hardware.

Wide patio spans belong on a patio door, not a tilt-turn sash. If that is the opening, we will say so.
