Here’s a structured breakdown of Sungye K5N Aluminum Casement Windows with key selling points and detailed explanations:


1. Reinforced 6063-T5 Aluminum Profile

High-strength alloy with 2.8mm thickness for durability and mid-rise structural stability.
The K5N uses 6063-T5 aluminum, precision-engineered for optimal strength-to-weight ratio. Its 2.8mm wall thickness and reinforced corner joints withstand wind loads up to 3,000 Pa, making it suitable for coastal and urban environments. The alloy undergoes anodizing and powder coating, ensuring resistance to corrosion, UV damage, and salt spray, with a lifespan exceeding 30 years.


2. Triple-Seal Thermal Insulation (U=1.0 W/m²K)

Dual PA66 thermal breaks + EPDM gaskets minimize energy loss.
Featuring dual polyamide (PA66) thermal barriers and triple EPDM seals, the K5N reduces heat transfer by 40% compared to standard windows. Independent testing confirms a U-value of 1.0 W/m²K, preventing condensation at -20°C and maintaining indoor comfort. The staggered chamber design disrupts thermal bridging, cutting HVAC costs by 20% in residential and commercial buildings.


3. Enhanced Security with 6-Point Locking

PAS 24:2016-certified anti-burglary system for residential safety.
Stainless steel shoot bolts engage at six strategic points, resisting up to 2,000N of forced entry. Tamper-proof hinge covers and reinforced strike plates deter crowbar attacks. The multi-directional locking mechanism integrates seamlessly with smart home systems, offering optional fingerprint or Bluetooth-enabled access control for modern security needs.


4. Effective Noise Reduction (Rw 42dB)

Laminated glass and asymmetric seals block 75% of urban noise.
The K5N combines 5mm laminated glass (0.38mm PVB interlayer) with triple EPDM gaskets to achieve Rw 42dB sound insulation. Its frequency-damping design neutralizes mid-range urban noise (e.g., traffic, construction), tested per ISO 10140-2 standards. Optional acoustic glass upgrades boost performance to Rw 45dB, ideal for schools or suburban homes near highways.


5. Aesthetic Flexibility & Customization

30+ RAL colors, woodgrain finishes, and slim 25mm sightlines.
Architects can customize interior/exterior finishes, including matte, metallic, or woodgrain textures, to match diverse design themes. The slim profile maximizes natural light penetration, while optional Georgian bars or curved glazing adapt to traditional or contemporary aesthetics. Pre-engineered templates support fast production for complex architectural projects.


6. Eco-Friendly & Low Maintenance

85% recycled aluminum and self-cleaning Nano-Coating™ surfaces.
Sungye’s closed-loop manufacturing recycles 85% of aluminum scrap, reducing carbon footprint by 35%. The hydrophobic Nano-Coating™ repels dust, rain, and pollutants, requiring only annual cleaning. Stainless steel hardware with PTFE lubrication ensures smooth operation for 50,000+ cycles, minimizing long-term maintenance costs.


Each feature is tailored to balance performance, aesthetics, and sustainability, positioning the K5N as a versatile solution for mid-range residential and light commercial projects.
