What is uPVC?

UPVC, also known as unplasticized polyvinyl chloride, is an easy-to-maintain building material used as a substitute for painted wood, mainly for window frames and sills when installing double glazing in new buildings, or to replace older single-glazed windows.

It has many other uses, including fascia, siding or cladding. The same material has almost completely replaced the use of cast iron for plumbing and drainage, which is used for waste pipes, drain pipes, gutters and drain pipes.

What is good to know?

What is good to know is that UPVC is a cheaper alternative to expensive hardwood and aluminum. It is a popular material due to its durability and cost-effective option. It may also be known as PVC and PVCU.


The incredible strength, versatility, and low maintenance comes from being manufactured using a vinyl polymer that is bonded to chlorine atoms, so the window frames are not actually plastic and can work well with steel. This means that homeowners will not have high running costs.

Currently, all UPVC windows and doors must be energy rated to comply with building regulations and are available in attractive colors and wood effect finishes.

Energy efficiency

If you are looking for energy efficiency, UPVC is a perfect choice, because energy-categorized UPVC windows are extremely thermally efficient. They have very low thermal conductivity as a result of the type of material used in production. This stops heat from escaping as easily as it can with some other building materials.

The main advantage

The main advantage of all high-quality UPVC products is that they never need painting, plus the only maintenance they usually require is wiping with a damp cloth once every few years.
