| Performance Parameter | Tested Standard / Grade | Engineering Feature | Application Benefit |
|---|---|---|---|
| Wind Pressure Resistance | Class 9 (up to 5000 Pa) | Thickened 6063-T5 aluminum extrusions | Suitable for coastal buildings and high-rise structures subject to severe wind forces. |
| Air Tightness | Class 8 (GB/T 31433) | Continuous EPDM sealing gaskets & interlocking sashes | Prevents dust, draft, and air infiltration; reduces indoor heating/cooling energy loss. |
| Water Tightness | Class 6 (700 Pa) | Stepped concealed drainage channels & dam design | Prevents water accumulation and overflow during heavy rainstorms. |
| Acoustic Insulation | Rw = 36 dB – 42 dB | Argon-filled Low-E double/triple tempered glazing | Effectively muffles city noise, traffic, and industrial background sounds. |
| Thermal Transmittance (U-Value) | U ≤ 1.2 – 1.8 W/m²K | Polyamide PA66 insulating strips & warm edge spacers | Complies with modern energy codes for low-carbon green building projects. |
Aluminum profile cutting and corner joint milling are executed to ±0.05 mm accuracy for tight, draft-free frame alignment.
