Non-Metal. Non-Conductive. Better Thermal Insulation.

When the outdoor temperature drops to -30°C, window profile material matters.

Compared with aluminum alloy and steel, PU fiberglass composite profiles have a much lower thermal conductivity coefficient, helping reduce heat transfer and improve indoor comfort.

✅ Non-metal material
✅ Non-conductive structure
✅ Low thermal conductivity: 0.114 W/m·K
✅ Helps maintain a more stable indoor temperature
✅ Suitable for high-performance window and building projects
