01What are uPVC windows and doors?

uPVC (Unplasticized Polyvinyl Chloride) is a durable, low-maintenance material widely used for making windows and doors. It is resistant to moisture, corrosion, and termites, making it a long-lasting choice for homes and offices.

India experiences extreme summers, monsoon rains, and humidity in many regions. uPVC windows & doors are waterproof, termite-proof, rust-free, and weather-resistant, ensuring long life with minimal upkeep.

From concept to reality, the team turned my vision into a stunning, livable space. I couldn’t be happier with this!

I recently had Polysash install new UPVC windows in my office, and I couldn't be happier with the experience. Their team was professional, efficient, and incredibly fast. The installation was completed in no time, and the quality of the windows is excellent. I highly recommend Polysash for their exceptional service and top-notch products.
