SGL Glass Curtain Wall Windows: Engineered for Durability and View
The definitive solution for panoramic views without compromising structural integrity or thermal performance.
When you specify glass curtain wall windows for a project, you aren't just buying glass; you are investing in the building's envelope performance. At SGL, we move beyond standard glazing. We provide a comprehensive curtain wall system designed to withstand hurricane-force winds, drastically reduce thermal transfer, and provide the sleek, "wall of windows" aesthetic that modern architecture demands.
Whether you are a general contractor managing a high-rise build or a homeowner designing a bespoke villa, our systems bridge the gap between heavy-duty commercial strength and refined residential luxury.

Why Choose SGL Curtain Glazing Systems?
Solving the "Fishbowl" Problem
A common failure in generic window walls is the "fishbowl effect"-where the interior becomes scorching hot in summer and freezing in winter due to poor insulation. Many contractors also face water infiltration issues after 3-5 years due to inferior sealants.
SGL solves this through engineering precision. Our glass curtain wall units utilize a thermally broken aluminum profile combined with double or triple silver Low-E glass. This setup blocks up to 70% of solar heat gain while maintaining high visible light transmittance. Furthermore, our proprietary triple-seal EPDM gasket system ensures airtightness that exceeds NFRC standards, effectively waterproofing your facade against driving rain.
Built for the Real World
We don't just test for static pressure; we test for dynamic reality. From seismic drift in earthquake zones to high wind loads in coastal areas, SGL curtain glazing is designed to flex and settle without cracking the glass or breaking the seal

FAQ
Q1: What is the difference between a "Window Wall" and a "Curtain Wall
A1: A curtain wall system hangs off the outside of the building structure (like a curtain), covering the floor slabs. A window wall sits between the floor and ceiling slabs. SGL manufactures both, but window walls are generally more cost-effective for residential high-rises as they don't require exterior installation equipment.
Q2: Can your system accommodate operable windows?
A2: We can integrate top-hung, awning, or casement vents seamlessly into the glass curtain wall grid. From the outside, the operable vents look identical to the fixed glass, maintaining a uniform facade aesthetic.
Q3: How do you handle shipping glass without breakage?
A3: We use fully enclosed plywood crates reinforced with steel bands. The glass units are separated by cork pads and shrink-wrapped. We have a breakage rate of less than 0.5% over the last 10 years of exporting. If breakage occurs, we ship replacements immediately.
Q4: What is the lead time for a custom order?
A4: After the shop drawing is approved, production typically takes 25-35 days depending on the complexity of the curtain glazing specs. Shipping time depends on your location.
Q5: Do you provide installation services?
A5: We primarily focus on manufacturing. However, for large commercial projects (>1000 sqm), we can send a technical engineer to your site to guide your local installation team on the correct anchoring and sealing procedures.
Q6: Is the system compatible with smart home glass?
A6: Yes, our profiles are designed with raceways to hide wiring. We can equip the frames with switchable privacy glass (PDLC) or motorized blinds inside the double glazing unit.
Q7: Can I get a sample corner section?
A7: Absolutely. We strongly encourage contractors to order a sample corner of our glass curtain wall windows to inspect the profile thickness, coating quality, and mechanism before placing a bulk order.
