What are uPVC Doors?
Polyvinyl Chloride (PVC) or Unplasticised Polyvinyl Chloride (uPVC) is a thermoplastic known for its recyclability, as it can be remelted and reused multiple times. The ‘u’ indicates that the plastic was not softened during manufacturing, so it retains its strength. Its unique composition provides exceptional strength and durability.
This durable material is used in a wide range of home improvement products, including bi-fold doors, front doors, uPVC windows and double-glazed windows.
