Aluminum Sliding Window

Walidor aluminum sliding windows are a practical choice for spaces that need easy operation, clear outdoor views, and better ventilation without requiring swing space. The horizontal sliding design allows the sash to move smoothly along a track, making it suitable for homes, apartments, offices, commercial spaces, and replacement projects.

Depending on your project, aluminum sliding windows can be reviewed with thermal break frame options, insulated glass, screen or net configurations, magnetic blinds, grille details, custom colors, and different size requirements. Series options can be compared based on frame structure, glass configuration, water tightness, wind resistance, sound insulation, and overall comfort needs.
