What Is a 90 Series Thermal Break Aluminum Window?
An SGL-90 Series thermal break aluminum window is an aluminum-framed window system with a nominal 90 mm frame width and an insulating barrier separating the internal and external aluminum sections. Aluminum is strong and dimensionally stable, but it also conducts heat. The thermal-break construction interrupts part of that direct aluminum path. Together with insulated glass and properly compressed seals, it gives the project team a more suitable basis for reviewing comfort, condensation risk, solar control, and energy performance than an unbroken aluminum frame alone.

How Is It Different From a Standard Aluminum Window?
| Topic | SGL-90 thermal-break aluminum window | Standard non-thermal aluminum window | What it means for a project |
|---|---|---|---|
| Frame construction | Inner and outer aluminum sections are separated by a thermal-break component | Aluminum sections can form a more continuous heat path | Thermal design needs are considered at the frame as well as the glass |
| Frame width | Nominal 90 mm system depth | Depth varies by system | More profile depth can accommodate the defined system design; it is not a performance rating by itself |
| Glass direction | Tempered double insulated glass standard; Low-E can be added | Glass selection varies | Glass can be aligned to safety, privacy, solar, acoustic, and thermal needs |
| Sealing | EPDM weather, air, and water seals | Seal arrangement varies by system | Proper fabrication and installation details are central to weather performance |
| Typical buying use | Projects that need a configuration-led window package | Simpler or lower-spec applications may use standard aluminum | Selection should follow location, façade exposure, budget, and project requirements |
The practical difference is not only the word "thermal." A project should review the whole assembly: profile sections, thermal-break structure, glass make-up, gaskets, drainage, hardware, sash size, wall interface, and installation method. That is why SGL asks for the project location and drawings before confirming a final configuration.
Which Window Types Can the SGL-90 Series Be Made Into?
| Window style | How it works | Where it is often considered | SGL-90 review points |
|---|---|---|---|
| Outward-opening casement | Side-hinged sash opens to the exterior | Villas, residential rooms, low-rise and façade openings | Check exterior clearance, wind exposure, screen arrangement, hinge side and cleaning access |
| Inward-opening casement | Side-hinged sash opens into the room | Residential, apartment, and renovation projects | Check furniture clearance, interior finishes, handle position, safety and drainage detailing |
| Top-hung | Sash is hinged at the top and opens from the bottom | Bathrooms, kitchens, corridors, high-level vents | Check reach, restrictor, opening angle, privacy glass and wind-driven-rain exposure |
| Tilt window | Sash tilts for controlled ventilation | Bedrooms, apartments, hotels, controlled-ventilation openings | Check ventilation strategy, restrictor, handle operation and safety requirements |
| Tilt-and-turn | One handle supports an inward side opening and a top-tilt ventilation position | Villas, apartments, hotels, and projects needing flexible ventilation | Check hardware selection, sash weight, opening limit, user operation and maintenance access |
| Fixed-plus-opening combination | Fixed panes are combined with operable sashes | Larger window walls, repeated elevations, offices and hospitality projects | Check sightlines, mullions, operable-vent positions, glazing and façade coordination |
What Sizes Can Be Made?
The SGL-90 Series is made to project dimensions rather than a one-size catalog range. SGL can review custom width, height, glass area, sash ratio, fixed-plus-opening layout, and mullion positions. The final maximum sash or panel size must be confirmed from the selected opening type, glass unit weight, hardware capacity, wind exposure, reinforcement requirement, and project drawings.
For a fast technical review, send a window schedule or list the width × height for each window type, quantity, opening direction, glass requirement, project floor level, and destination. This lets engineering separate a small bathroom top-hung window from a large villa casement or a repeated apartment tilt-and-turn unit.
Why Choose an Aluminum Frame Design?
Aluminum frames are considered when a project needs a precise, architectural frame material that can be formed into repeated or custom configurations. With 6063-T5 aluminum alloy, a powder-coated finish, insulated-glass options, and suitable hardware, the SGL-90 system can be reviewed for villas, apartments, hotels, and commercial projects.
The reason is practical: the frame must carry the chosen glass and hardware, retain the intended opening geometry, coordinate with façade colours, and support the sealing and drainage strategy. Aluminum is not a universal answer on its own. The right system comes from matching the aluminum profile, thermal break, glass, seals, hardware, and wall connection to the project environment.
Aluminum Profiles: 6063-T5 alloy, 1.8 mm wall thickness, 90 mm frame depth, powder-coated finish.
The SGL-90 frame is constructed from 6063-T5 aluminum alloy, featuring a nominal profile wall thickness of 1.8 mm and a frame depth of 90 mm. Different configurations-such as small top-hung sashes, large tilt-and-turn sashes, and combined fixed-and-operable window wall systems-impose varying requirements regarding structural loads and hardware specifications.
The standard surface finish is powder coating. Final color selection should be based on approved RAL color charts, project color schedules, or physical samples. Please specify any special requirements regarding gloss levels, textures, dual-color finishes, weather-resistant coatings for coastal environments, or third-party coating certifications in the Request for Quotation (RFQ) to ensure the surface treatment plan is reviewed prior to production.
Glazing: Tempered double-glazed insulating glass units (Low-E glass optional).
The SGL-90 comes standard with tempered double-glazed insulating glass units (IGUs). This serves as a practical baseline configuration for projects requiring insulating glass and safety glazing; however, the final glass composition must align with actual opening dimensions and specific project design requirements. Low-E glass may be specified if performance criteria such as solar shading, thermal insulation, condensation resistance, or indoor comfort are to be factored into the overall window system assessment.
Hardware: Guitto (Standard Configuration).
The SGL-90 series features Guitto hardware as standard. Guitto is a high-quality (Grade A) door and window hardware brand of Danish design, backed by a 10-year warranty. Depending on the chosen configuration, the hardware package may include components such as handles, hinges, multi-point locking systems, support stays, limiters, or tilt-and-turn operating mechanisms.
Sealing System: EPDM (Ethylene Propylene Diene Monomer) weather, air, and water seals.
The SGL-90 series utilizes EPDM sealing gaskets specifically engineered to provide weather-resistant, airtight, and watertight performance. The performance of the sealing system is closely linked to window frame geometry, sash compression, glazing installation, drainage paths, corner detailing, sill design, and the construction of installation interfaces. Proper design in all these areas is essential for the window to effectively withstand wind and rain and control air infiltration.
For projects located in exposed, damp, high-humidity, extreme-heat, or extreme-cold environments, please provide elevations, building height, wall assembly details, and data on rainfall and wind conditions (if available). This will enable the technical review to focus on actual environmental conditions rather than relying solely on generic weather-resistance performance claims.
