LR-2100 Uninsulated Sliding System
A clean aluminium sliding system for interiors and partitions where no thermal break is needed: a centre mullion half as wide as usual, sashes up to 120 kg and monorail or 3-track frame options.
LR-2100 is the economical sliding solution of the LineaRossa LR series. With a 32 mm sash and a 44 mm frame it maximises the glazed area and carries 20–22 mm single or double glass. The hollow centre detail reinforced with a polyamide profile keeps the structure rigid even in projects that do not require a thermal break. It suits balcony-to-living-room dividers, winter-garden partitions, office and shop enclosures.
Key features
01 · Minimal centre mullion
A centre mullion 50% slimmer than standard sliders leaves glass instead of profile where the two sashes meet, so the room reads brighter.
02 · Frame to suit the project
Monorail (single track) or 3-track frame; 45° or 90° sash joints. Different openings are solved with the same profile set.
03 · Multi-point locking
A multi-point lock designed for the sliding sash ties the sash to the frame along its full height: resistance to forcing and a tight close.
04 · Polyamide hollow centre
A 20 mm polyamide profile placed in the hollow centre prevents sash deflection and supports a long service life.

Can a fly screen be fitted?
Yes. A fly screen compatible with the frame is applied to the outer track of the 3-track frame.
