Combination Awning / FIX Atis

With the aim of delivering an optimal window-opening solution for modern living spaces, TOSTEM introduces the Atis top-hung window combined with fixed glass panel. This smart combination integrates two window types within a single frame system, enhancing usability while maintaining the architectural façade’s visual appeal.

Multi-functional structure for effective ventilation and daylight

The window is designed with a top-hung sash that tilts outward along a horizontal axis, allowing natural ventilation without rain intrusion. Below it, a fixed tempered glass panel maximizes natural light entry into the interior. This structure optimizes daily functionality while ensuring high safety in all weather conditions.

Flexible operation mechanism with outstanding durability

The top-hung sash operates with a turn handle and a sliding hinge system, allowing users to open the window at various angles. For ventilation, simply rotate the handle to adjust the tilt as desired. The fixed glass panel remains stationary, preserving the open view without obstruction. The system features EPDM gaskets and multi-point locking for superior sealing performance, offering excellent dust resistance, water tightness, and sound insulation—even when the sash is open.

This operation mechanism is especially useful in urban environments where ventilation is needed under unpredictable weather, while keeping the interior clean and quiet.

An ideal solution for modern urban housing

This window configuration offers an open and airy living experience while ensuring security and privacy. The combination of top-hung and fixed glass design increases natural light and expands interior views, without disrupting the overall building layout. With a sound insulation rating of up to 25dB, it is an ideal choice for high-rise apartments and urban townhouses that require effective noise control.

High aesthetic value with architectural flexibility

Part of the ATIS aluminum system, this product features a minimalist design with clean, refined lines that complement modern architectural trends. It can be flexibly combined with various glass panel styles to create attractive façade compositions. The slim yet sturdy aluminum frame enhances the glass surface area, offering wider views and a sleek appearance for the end user.
