What are uPVC windows?

The abbreviation uPVC stands for unplasticized polyvinyl chloride and is the material that the frames of double-glazed windows are made of. Over the past few years, uPVC windows have become a popular choice among property owners for many reasons, including being affordable, low maintenance and thermally efficient. Our uPVC windows are available in a wide selection of finishes and whether you’re looking for a traditional appearance, such as a likeness for authentic wood, or would like minimalist, modern windows, we have the options for you.

How do uPVC windows work?

As mentioned, uPVC is the material that surrounds two panes of glass to create double-glazed
windows. In this way, there is a space between the two panes of glass which allow air to be trapped
and act to support three main purposes:

  1. The air provides insulation which doesn’t allow cold or hot air to pass through the property.
  2. It prevents condensation from forming within the property.
  3. It works to reduce noise pollution by minimising the sound that can pass through.


For over 20 years we have seen our customers enjoy the many benefits that uPVC windows provide first-
hand. Here’s why they are the top choice for so many of our customers…


Our uPVC windows are highly waterproof and don’t absorb water or moisture in the ways that wooden windows do. As they are non-porous and non-corrosive, they also won’t expand or contract over time and will maintain their structure and functionality for years.

Durable & Resilient

A great benefit of uPVC windows is that they are highly durable and resilient and can last up to 35 years if they're maintained properly. Our uPVC windows are manufactured, supplied, and installed to exceptionally high standards using high-quality materials.

Thermally Efficient

This window type is highly popular due to the thermal efficiency it boasts and they were specifically designed with heat and energy insulation in mind, therefore, saving you money on your energy bills and reducing your carbon footprint.


Patio doors are proven to be highly secure thanks to their modern design and the technologies used to manufacture and install them. You can be confident that they provide greater levels of long-lasting protection and security for your complete peace of mind.

Easy to Maintain

uPVC windows are incredibly easy to maintain and, aside from cleaning them with soap and water every so often, require very little maintenance over time. Additionally, they are scratch resistant and won’t suffer abrasions or peel.

Simple Installation

Unlike other types of windows, our uPVC windows are easy and simple to install and with our experience and skills, we can quickly install them for a completely hassle-free experience.


Compared to other window types, uPVC windows are by far the most affordable option – without compromising on the quality that you receive. Not only this but as they require little maintenance or repairs, they have a long lifespan – saving you money in the future.

What is the difference
between uPVC and PVC windows?

The main difference between uPVC (unplasticized polyvinyl chloride) and PVC (polyvinyl chloride) windows is that, unlike PVC windows, uPVC doesn’t have any plasticiser added. There are very few differences in functionality between the two and both boast innumerable benefits for your window supply, installation and function.
