STE-4000 Window
A high-performance commercial aluminum window
The STE-4000, classified as AW (Architectural Window), is a high-end window designed for projects where quality is paramount: multi-residential towers, hotels, institutional buildings, and large-scale renovation projects. This exceptional quality window represents a high-performance solution in terms of durability and overall building envelope performance.
Available configurations
The STE-4000 series comes in two configurations to adapt to the needs of each project
STE-4000 FIXED WINDOW
The fixed configuration of the STE-4000 is designed to offer maximum performance in thermal and acoustic insulation. It incorporates double or triple thickness insulating glazing and optimized thermal break profiles.
It allows for large glazed surfaces while maintaining the structural rigidity and dimensional stability of the frame.

A window designed for performance, occupant well-being and flexibility for your projects.
Energy performance
Energy performance is at the heart of current concerns. Thanks to its double and triple thickness glazing, thermal breaks and high-end sealing joints, the STE-4000 ensures optimal air and water tightness.
Structural capacity and certified sealing
Rated AW (Architectural Window), the STE-4000 is tested according to the most demanding standards. Its robustness allows it to withstand the high wind loads typical of residential towers, without any deformation or sagging.
Simple and adaptable installation
Designed for quick installation, the STE-4000 features modular or structural frames that adapt to all site conditions: new construction or renovation, insertion into precast concrete or integration with Multifacade systems.
Comfort and flexibility for occupants
The STE-4000 window offers great freedom of use. Its opening sashes allow interior spaces to be ventilated and improve occupant well-being without compromising aesthetics.
The STE-4000 window and modern architecture
Current trends favor minimalist profiles and extended glass surfaces. Thinner frames maximize natural light and visual continuity, while meeting insulation and energy efficiency requirements.
Modern systems incorporate double or triple glazing with low-emissivity treatments, reducing heat loss and excessive solar gains.
Aluminum remains a preferred material to meet these criteria: its rigidity allows for large openings, while its durability and recyclability make it a choice consistent with sustainable construction approaches.
These technical advances now make it possible to design lightweight, continuous and high-performance facades, while meeting the aesthetic and energy requirements of contemporary buildings.
Do you want to integrate the window into an existing system?
The STE-4000 integrates seamlessly into various facade systems to meet your project's specific needs.
Multifaçades
The STE-4000 commercial window integrates perfectly with the Multifacade system, forming a harmonious and high-performance ensemble. Together, they offer refined design and exceptional energy efficiency, maximizing glazed surface performance while meeting the highest demands of the North American market.
Murs-Rideaux
It can also be combined with classic curtain walls to create fully glazed facades. Thanks to its robust aluminum frame and modular design, the STE-4000 ensures seamless integration into our curtain walls while maintaining the thermal and structural performance requirements specific to contemporary architectural projects.
Precast Concrete
The integration of the STE-4000 window into precast concrete represents a modern and efficient solution for designing high-performance and durable envelopes. Thanks to its aluminum frame, the STE-4000 adapts perfectly to the tolerances and constraints of concrete, ensuring a watertight, stable and uniform junction.
A word on building envelope retrofitting
For retrofitting, the STE-4000 commercial window represents an effective solution to modernize facades while improving the energy performance of existing buildings.
Its aluminum frame provides the necessary strength and durability to adapt to different structures, whether concrete, steel, or masonry. Thanks to its modularity, it facilitates the integration of new openings or the replacement of windows without altering the continuity of the envelope.
Compatible with Multifacade and curtain wall systems, it allows for partial or complete facade retrofitting, while standardizing the appearance and overall performance of the building.
Its performance helps reduce heat loss, improve indoor comfort, and extend the lifespan of the renovated envelope. Our approach ensures long-term financial returns on the building for all our partners in retrofitting projects.

Frequently Asked Questions
What makes the STE‑4000 commercial window series a high‑performance choice for multi‑residential towers, hotels, and institutional buildings?
The STE‑4000 is classified AW (Architectural Window) and is engineered for high wind loads and demanding thermal/acoustic performance. Its aluminum frame incorporates large thermal breaks and high‑quality gaskets, ensuring exceptional air‑ and water‑tightness. Double or triple glazing options, robust structural capacity and compliance with the highest standards make it suitable for towers, hotels and retrofits.
What configuration options does the STE‑4000 window offer, and how do they benefit different projects?
- Fixed window: optimized for large glazed areas with maximum thermal and acoustic insulation. It uses double or triple insulating glass and a thermally broken frame, and it integrates seamlessly into curtain wall or Multifaçades systems.
- Operable window: available as casement, awning, hopper or tilt‑and‑turn (interior opening). High‑performance hardware provides smooth operation and uniform seal compression for superior air and water tightness. These options allow natural ventilation and user comfort while maintaining performance.
Both fixed and operable windows can be integrated into curtain walls, Multifaçades panels or precast concrete systems.
What are the dimensions of STEKAR’s commercial window?
The system allows generous dimensions. In operable configurations, typical opening sizes can reach approximately 5 ft × 7 ft (1.5 m × 2.1 m), depending on wind load and hardware selection. Fixed windows can span up to roughly 8 ft in height and 5 ft in width. Exact limits vary by project and should be confirmed with STEKAR’s engineering team during design.
