Learn about the properties of uPVC windows: when is it worth choosing them?

Here’s a bit of history – uPVC windows, known for their affordability and easy maintenance, have evolved significantly since their rise in popularity in the 1980s. These windows, made from unplasticised polyvinyl chloride, are a top choice for homeowners in the United Kingdom seeking durable, well-insulated, and cost-effective window solutions.

Versatility and design

Modern uPVC windows are not limited in style. They are available in various colours, textures, and configurations, fitting both double and triple glazing. This versatility allows them to complement any home style, from new builds to Victorian terraces. Furthermore, uPVC windows are among the most affordable options in the market, costing about from 50% up to 200% less than aluminium windows and 50% less than wooden frames.

Types of uPVC windows:

  • Casement uPVC Windows
  • Sliding uPVC Windows
  • Tilt and Turn uPVC Windows
  • Sash uPVC Windows
  • Fixed uPVC Windows
  • Bow and Bay uPVC Windows

Comparative advantages

When compared to timber, aluminium, and composite frames, uPVC windows excel in energy efficiency, security, and appearance. They are easier to clean and maintain than timber, more cost-effective than aluminium, and, while not as long-lasting as composite windows, they offer a balance of efficiency and affordability.

Customisation options

A major benefit of uPVC windows is the wide range of colours and finishes available, allowing homeowners to tailor their windows to match their home’s interior design. While white frames are the cheapest, more unique colours and wood grain finishes are also available, though at a higher cost. These options significantly enhance the curb appeal and value of a property.

Energy efficiency and noise reduction

The choice between double and triple glazing units in uPVC windows depends on the homeowner’s priorities. Triple glazing offers superior insulation and energy efficiency but at a higher cost. Conversely, double glazing provides good warmth retention and soundproofing, with some uPVC casement windows reducing noise by up to 70%.

Purchasing and environmental considerations

The uPVC windows can be bought off the shelf or customised for unique properties. It’s crucial to engage FENSA accredited (UK market only) installers for fitting. Despite being a plastic product, uPVC windows, when maintained well and recycled at the end of their lifespan, can have a minimised environmental impact. They typically last between 20–35 years, offering a balance of style, security, and budget-friendliness.

When is it worth choosing uPVC windows?

Choosing uPVC windows is particularly advantageous in several scenarios. If you’re seeking a cost-effective solution without compromising on quality, uPVC windows are a top choice due to their lower price point compared to alternatives. They are ideal for homeowners prioritising low maintenance, as they require minimal upkeep and are durable against various weather conditions. 

For those living in noisy areas, uPVC windows with a double or triple glazing unit can significantly reduce external noise. Additionally, if you’re looking to improve your home’s energy efficiency, these windows offer excellent thermal insulation, potentially lowering heating costs. Their versatility in design and colour options makes them suitable for both modern and traditional homes, ensuring they can seamlessly match your property’s aesthetic. 

Therefore, whether you’re renovating a period property, constructing a new build, or simply looking to upgrade your windows within a budget, uPVC windows present a practical, stylish, and economically sound choice.


The uPVC windows are a worthwhile choice for homeowners in the UK, offering a blend of affordability, durability, and energy efficiency. Their adaptability to various home styles, coupled with their low maintenance and environmental considerations, makes them an attractive option for those looking to replace or install new windows.
