At SunFrame, we see curtain walls and windows as the breathing system of a building — regulating light, air, and energy while shaping how people experience the space inside.
Step into our production line and you’ll see workers inspecting every glass panel carefully, as if putting a custom protective coat on the building.
SunFrame’s Low-E curtain wall systems wrap each building in energy-smart protection, orchestrating natural light, thermal comfort, and long-term performance. By integrating advanced Low-E insulated glass with high-strength laminated panels, our systems not only enhance energy efficiency but also meet safety and aesthetic requirements for commercial, residential, and public projects.
Different climates and building functions demand different insulation performance. Thermal tests on several completed projects show that triple-silver Low-E insulated glass can reduce air-conditioning energy consumption by 15%–20% compared to standard insulated glass, while maintaining excellent natural lighting.
Type | Typical Configuration | U-Value (W/m²·K) | Solar Heat Gain (%) | Visible Light Transmittance (%) | Typical Applications |
Single-silver Low-E Insulated | 6+12Ar+6 | 1.2 | 55 | 72 | Residential / Standard Offices |
Double-silver Low-E Insulated | 6+12Ar+6 | 0.9 | 42 | 68 | Commercial Curtain Walls |
Triple-silver Low-E Insulated | 8+18Ar+8 | 0.4 | 38 | 65 | Passive Houses / High-End Projects |
Heat-Reflective Coated Glass | 6mm | 5.8 | 28 | 70 | Hot Climate Areas |
We can customize glass combinations for each curtain wall project based on local climate, orientation, and energy-saving objects.
One notable case is the Guyana CJIA Airport Expansion. SunFrame supplied an exposed frame curtain wall system with blue-grey Low-E laminated insulated glass, bringing daylight into the terminal while reducing cooling loads in the tropical climate. Aluminum veneer panels were added at the perimeter, acting as both protective closures and architectural accents.
Beyond appearance, the facade cut energy use, held up against coastal weather, and was delivered on a tight schedule. Learn more in the CJIA Airport Expansion curtain wall project ›
In high-rise, coastal, and public buildings, glass safety performance is critical.
Multiple impact and wind load tests show that curtain walls using SGP high-strength laminated glass significantly enhance safety in extreme weather conditions.
Type | Features | Typical Applications |
Tempered Glass | Breaks into blunt particles to reduce injury | Public buildings, Residential |
PVB/EVA Laminated Glass | Prevents splintering, impact-resistant | High-traffic areas, Exhibition halls |
SGP High-Strength Laminated Glass | Higher impact resistance and weather durability | High-rise, Coastal buildings |
Bulletproof Glass | Multi-layer lamination for ballistic resistance | Financial institutions, Security buildings |
Smart liquid crystal dimming glass is ideal for premium commercial, office, or meeting spaces. It can switch between transparent and frosted modes. This feature maintains natural light and ensures privacy.
Maintenance costs and frequency for large public buildings or high-rise facades must be considered at the design stage.
Photocatalytic self-cleaning glass can break down and wash away surface dirt with natural rainwater, reducing cleaning frequency by over 30% compared to regular glass.
Type | Features | Typical Applications |
Digital / Silk-Screen Printed Glass | Custom patterns with controlled translucency | Decorative facades, Brand buildings |
Curved Tempered Glass | Arc shapes with tempered safety | Shaped curtain walls, Corner facades |
Fire-Resistant Glass | 1–2 hour fire resistance per GB12513 | High fire-protection requirements |
SunFrame curtain wall and glass systems have passed multiple international tests:
▶ USA: AAMA 2603/2604, ASTM E1300, ASTM E2190
▶ Europe: EN 14351-1, EN 12150, EN 356
▶ Australia: AS2047, AS4284
▶ Japan: JIS H4100/H8601/H8602
▶ UK: BS 6496
▶ Middle East (GCC): High-temperature and wind-sand resistance tests
Our certifications confirm more than numbers: the systems resist storms, save energy, and stay structurally sound even under fire or impact. In practice, that means dependable performance whether in humid tropics or freezing winters.
Commercial Curtain Walls: Double-silver Low-E + High-strength laminated glass
→ Keeps interiors bright while reducing cooling costs in office towers and malls.
Residential Windows: Single-silver Low-E insulated glass
→ A cost-effective way to improve comfort and cut heat transfer in homes.
High-End Energy-Efficient Buildings: Triple-silver Low-E + Vacuum layer
→ Achieves ultra-low U-values, ideal for projects aiming for passive house standards.
Public Buildings: Self-cleaning glass + Laminated glass
→ Lowers cleaning frequency and provides added safety for busy public spaces.
At SunFrame, glass is the foundation, but the real value lies in the system — combining performance, safety, and design in one complete solution.
From the first choice of glass to the final assembly line, every detail is shaped with one aim — reliability that stands the test of time. Our projects show that the right façade system not only saves energy but also gives owners peace of mind for decades.
