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.
Multifacades
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.

Frequently Asked Questions
Why is the STE-4000 a high-performance commercial window for high-rise residential, hospitality, and institutional projects in the U.S.?
The STE-4000 commercial window series is an AW-rated (Architectural Window) aluminum system designed for demanding building envelopes in high-rise residential towers, hotels, institutional buildings, and large-scale retrofit projects. Engineered for high wind loads and strong thermal and acoustic performance, the system features an aluminum frame with large thermal breaks, high-quality gaskets, and durable components that support excellent air tightness, water resistance, and long-term performance.
Available with double- or triple-glazed insulating glass, the STE-4000 is built to meet the performance expectations of complex projects in the United States where durability, occupant comfort, and envelope reliability are critical. Its structural capacity and refined integration potential make it a strong option for both new construction and façade modernization programs.
What window configurations are available in the STE-4000 series?
The STE-4000 aluminum commercial window is available in both fixed and operable configurations, allowing design teams to balance aesthetics, ventilation, and performance based on project requirements.
Fixed windows are ideal for large glazed areas where strong thermal performance, acoustic control, and a clean exterior appearance are priorities. They can be built with double or triple insulating glass and integrate well into curtain wall systems, Multifaçades assemblies, and precast façade applications.
Operable windows are available in multiple formats, including casement, awning, hopper, and tilt-and-turn. These options provide natural ventilation and occupant control while maintaining high performance. High-quality hardware helps ensure smooth operation and consistent seal compression, contributing to strong resistance against air leakage and water infiltration.
What sizes are available for the STE-4000 commercial window system?
The STE-4000 commercial window system supports generous dimensions suitable for many large-scale commercial and institutional applications. In operable configurations, typical vent sizes can reach approximately 5' x 7' (1.5 m x 2.1 m), depending on project-specific wind loads, hardware selection, and performance requirements.
For fixed applications, glazing areas can extend up to approximately 8' high by 5' wide. Final sizing depends on the structural and performance criteria of each project, and all dimensions should be reviewed with STEKAR’s engineering team during the design and specification phase.
What makes the STE-4000 commercial window series a high-performance choice for high-rise residential, hotel, and institutional buildings?
The STE-4000 commercial window series is an AW-rated (Architectural Window) aluminum system designed for demanding building envelope applications, including high-rise residential towers, hotels, institutional buildings, and large-scale retrofit projects. It is engineered to withstand high wind loads while delivering strong thermal and acoustic performance.
Its aluminum frame features large thermal breaks and high-quality gaskets that help provide excellent air tightness and water resistance. Available with double- or triple-glazed insulating glass, the system offers the durability, structural strength, and long-term performance required for complex commercial projects. Its robust design makes it a reliable solution for architects, façade consultants, and developers seeking a high-performance window system for demanding climates cross the U.S.
What configuration options does the STE-4000 commercial window offer?
The STE-4000 commercial window system is available in both fixed and operable configurations, giving project teams the flexibility to meet performance, ventilation, and design goals across different building types.
The fixed window configuration is ideal for large glazed openings where high thermal efficiency, strong acoustic insulation, and a clean exterior appearance are priorities. It can incorporate double or triple insulating glass within a thermally broken frame and integrates easily into curtain wall systems, Multifaçades assemblies, and other prefabricated façade systems.
The operable window is available in casement, awning, hopper, and tilt-and-turn configurations. These options allow for natural ventilation and occupant comfort while maintaining strong envelope performance. High-performance hardware supports smooth operation and consistent seal compression, helping improve air and water tightness over time.
What sizes are available for STEKAR’s STE-4000 commercial window?
The STE-4000 commercial window supports generous dimensions suited to many large-scale façade applications. In operable configurations, typical opening sizes can reach approximately 5 ft x 7 ft (1.5 m x 2.1 m), depending on project-specific wind loads, hardware selection, and performance requirements.
In fixed configurations, units can span up to approximately 8 ft high by 5 ft wide. Final size limits will vary based on the structural and performance criteria of the project and should be confirmed with STEKAR’s engineering team during the design and specification process.
