Sliding Systems
Eight sliding systems, from a balcony door to a 4-metre living-room opening: a family that spans uninsulated interior sliders, lift-and-slide and minimal systems with concealed frames.
Three questions decide the choice of sliding system: is thermal insulation needed, how heavy is the sash, and how visible may the frame be? LineaRossa offers eight answers along these axes. LR-2100 and LR-2200 are uninsulated for unheated spaces; LR-3100 and LR-3200 are standard insulated sliders with a 21 mm thermal break; LR-3500 carries 400 kg sashes with its lift-and-slide mechanism. In the Grande series GLR-33 gives the highest insulation with glass up to 60 mm, GLR-36 a seamless passage with its flush threshold, and GLR-37 a minimal look with concealed frames.

Frequently asked questions
Which one for an insulated balcony door?
LR-3100 for standard residential balcony doors; LR-3200 or LR-3500 if the sash exceeds 120 kg. For an unheated partition inside an enclosed balcony, LR-2100 is enough.
How are fly screens handled on sliding systems?
All LineaRossa sliders have a fly screen option compatible with the frame; in GLR-36 the screen is fully integrated into the sash profile.
When is lift-and-slide necessary?
When the sash exceeds 120 kg or a single sash wider than 2.5 m is required, the LR-3500 lift-and-slide mechanism moves the heavy sash effortlessly.
