UPVC مخفف عبارت Unplasticized PolyVinyl Chloride به معنای پلی‌وینیل کلراید سخت‌شده است. حدود ۸۵ درصد ترکیب پروفیل‌های پنجره UPVC را این ماده تشکیل می‌دهد. ساختار اصلی این متریال از ترکیب نفت خام و نمک طعام حاصل می‌شود؛ به‌طوری که اتیلن از نفت خام و کلر از نمک به دست می‌آید. این ترکیب، ماده‌ای مقاوم و پایدار را ایجاد می‌کند که در صنایع مختلف، به‌ویژه ساخت درب و پنجره، کاربرد گسترده‌ای دارد.

UPVC stands for Unplasticized Polyvinyl Chloride—a rigid form of PVC that constitutes approximately 85% of the material used in UPVC window profiles. Its base components are derived from crude oil and common salt, with ethylene extracted from petroleum and chlorine from salt. This combination produces a strong, stable material widely used across industries, particularly in the manufacturing of doors and windows.

UPVC (Unplasticized Polyvinyl Chloride) windows are among the most cost-effective and durable options for door and window systems. These products offer outstanding thermal performance and sound insulation while requiring minimal maintenance over their long service life. For larger frames, galvanized steel reinforcements are integrated to increase structural strength. Their resistance to rust, decay, and discoloration, along with full recyclability, makes UPVC windows a sustainable and environmentally friendly choice.
