LR-3100 Insulated Sliding System
LR-3100 combines a slim profile with strong thermal, water and air tightness, giving balconies, terraces and living-room openings expansive glass with smooth, secure and effortless operation.
LR-3100 is LineaRossa's most widely installed insulated sliding system. A 21 mm polyamide thermal break and 30–32 mm double glazing cut energy loss, while the 32 mm sash and 44 mm frame keep the look slim. Sashes up to 120 kg, a 34 mm centre mullion that is 50% slimmer, multi-point locking and a fly-screen-track frame option make it the default choice for residential and commercial projects.
Key features
01 · Minimal architectural solution
The 50% slimmer centre mullion gives a larger glazed surface and a clean look; at 90° sash joints the 34 mm middle sash lets in more daylight.
02 · High-security locking
A high-strength multi-point lock ties the sash to the frame at several points, improving security and operating control.
03 · Thermal efficiency
The 21 mm thermal break and polyamide-insulated centre detail interrupt the thermal bridge for energy savings and indoor comfort.
04 · Easy fabrication and installation
A low part count reduces labour time and complexity: fast fabrication in the Ferrini workshop, fast installation on site.
