GP 56L, a double wall aluminum extruded profile, offers sound insulation as a main advantage. This is achieved by introducing hard extruded PVC in the groove section and co-extruded (soft / hard) PVC in the hook section of the profile.
The aluminum vertical guide of the GP 56L is equipped with 2 hard PVC profiles, keeping frictions at a minimum. Two fins inside the guide help the slat not to come apart of the track, allowing wider openings.
