What Is a Sliding Window?

A sliding window consists of one or more movable sashes that slide horizontally along tracks instead of opening inward or outward.

Because they require no additional opening space, sliding windows are ideal for:

• Apartments
• Offices
• Balconies
• Kitchens
• Living rooms
• Commercial buildings
• High-rise projects

Their simple mechanism also reduces maintenance compared to many hinged systems.

Two-Panel Sliding Window

One fixed sash and one movable sash.

Ideal for small and medium-sized openings.

Two Sliding Panels

Both sashes can move independently for improved ventilation.

Three-Panel Sliding Window

Typically includes a fixed center panel with two sliding side panels.

Suitable for wide openings.

Multi-Panel Sliding Systems

Large commercial or luxury residential projects often use multiple sliding panels to maximize natural light and panoramic views.
