In India’s evolving construction landscape, Aparna Enterprises Limited has emerged as a leader in next-gen fenestration through its range of uPVC windows and doors. With an unwavering focus on quality, precision, and eco-conscious materials, Aparna offers a complete vertical—starting from raw profile manufacturing under Ökotech to final product fabrication and installation through Venster.
Why uPVC Is the Preferred Choice
uPVC (Unplasticized Polyvinyl Chloride) is the gold standard in modern window and door systems. Known for its:
- High resistance to weather and chemicals
- Low thermal conductivity for energy efficiency
- Excellent noise reduction
- Low maintenance and long life
uPVC frames do not rot, warp, or fade like traditional materials, making them ideal for Indian climates ranging from humid coasts to hot interiors.

Venster, a flagship brand from Aparna, offers customizable and ready-to-install uPVC windows and doors for homes, offices, and high-rise buildings. Some popular types include:
- Sliding Windows & Doors – Space-saving and ideal for balconies or patios
- Casement Windows – Airtight sealing for maximum insulation
- Tilt-and-Turn Windows – Dual functionality with enhanced airflow
