The Challenge
In dense urban environments and compact living spaces, traditional swing windows waste valuable interior and exterior space when opened. Balconies, corridors, and tight floor plans need windows that open without projecting into usable space — while still delivering the thermal and acoustic performance modern buildings demand.

Common Questions
2-track is standard for most residential applications. 3-track allows 2/3 opening area and is popular for balcony enclosures. 4-track provides maximum flexibility for large openings where panels can stack to one or both sides.
Modern thermal break sliding systems achieve Uw values of 1.4-1.8 W/(m²·K), which is excellent for most climates. However, casement windows achieve slightly better air-tightness due to compression seals vs. sliding seals.
