UPVC (unplasticised polyvinyl chloride) windows are a type of window made from uPVC material, which is an unplasticised version of traditional uPVC. UPVC has greater rigidity and strength compared to regular uPVC, making it an ideal material for windows and doors. UPVC windows are weatherproof, non-corrosive, do not require painting and are easy to maintain, making them a very popular choice in the construction industry.
The difference between uPVC and uPVC is mainly that uPVC does not contain plasticisers, which are added to traditional uPVC to make it more flexible. For this reason, UPVC is more rigid, hard and resistant to temperature changes and mechanical damage. PVC, on the other hand, with plasticisers, is more flexible but less durable and resistant to damage, which is why it is not used for window manufacturing.
