Customer Value: More comfortable year-round temperature differences in outdoor spaces, gazebos resistant to winds up to Grade 10, 20-year maintenance-free outdoor use, and installation labor costs reduced by 30%

In addition to standardized energy-efficient profile inventory, CNW also supports custom mold development for differentiated thermal break structures tailored to each country’s energy-efficient building standards, assisting customers in obtaining PHI passive house certification and CE compliance.

4. Core Advantages

Exclusive Isotermal Thermal Break Technology: Utilizing PA66 GF25 thermal break strips arranged in an isotermal layout, combined with multi-chamber profile structures, dramatically reduces thermal conductivity. Certified through Germany’s PHI Passive House thermal testing, this represents a key differentiating selling point for high-end energy-efficient windows and doors in Europe, helping customers command a 25% premium on their products.

Climate-Adaptive Sealing System: All window and door models come standard with triple-layer EPDM sealing strips, achieving airtightness rating of 8, watertightness rating of 6, and wind-pressure resistance rating of 9, suitable for Southeast Asian rainy seasons, European frigidity, and North American coastal areas with high salt mist, significantly reducing post-sale complaints about leaks and drafts.

Comprehensive Weather-Resistant Surface Treatment Ensuring Longevity of Insulated Profiles: With proprietary vertical powder coating and wood-grain transfer lines, undergoing salt-spray tests lasting ≥500 hours, the integrated process ensures that thermal break strips and profiles remain crack-free, maintaining consistent insulation performance even under long-term outdoor conditions.

Vietnamese Localized Mass Production Guarantees Delivery Timeliness: Monthly production capacity of 1,500 tons of insulated profiles, with regular stock delivered within 20–25 days and custom-molded products ready in 30–35 days, meeting the seasonal bulk order demands of overseas window and door manufacturers.
