Ultraglide
Smooth lift & slide at a sharp price point.
Application Example
Overview
What makes the Ultraglide
stand out.
Aliplast Ultraglide is a lift & slide system built for large openings with three insulation tiers: UG (standard), UGi (insulated), and UGi+ (premium insulation with foam inserts). All variants handle panels up to 440 kg with smooth one-finger operation. The MaxLight variant pushes sightlines to a minimum for maximum glass area. Corner solutions - both glass-to-glass and sash-to-sash - enable panoramic installations. At a price point below the premium lift & slide platforms, Ultraglide makes European lift & slide accessible to a wider range of projects.
