UPVC
uPVC (Unplasticized PolyVinyl Chloride) is a high performance building material widely used around the world for premium windows and doors. Known for its durability, energy efficiency, and low maintenance, uPVC has become the preferred alternative to traditional materials like wood and aluminum.
At Okna.id, we focus exclusively on uPVC windows and doors because they deliver the best long term value for Indonesian homes and buildings. Indonesia’s tropical weather intense heat, humidity, and heavy rainfall requires materials that can withstand the elements. uPVC is engineered to remain stable and strong in harsh environments.
Key Climate Benefits

• Corrosion free: Unlike metal frames, uPVC will never rust.
• Thermal insulation: Helps keep indoor temperatures cooler, reducing AC usage.
• Soundproofing: Ideal for noisy urban settings thanks to superior acoustic insulation.
