uPVC vs Timber Windows: Which One To Choose?

Struggling to decide on whether to choose uPVC windows or timber windows? Hopefully, we can make it easier for you!

If you’re looking to replace your existing windows but unsure of where to start, we’ve created an easy guide just for you. We understand that it may feel challenging to make the right decision when you’re swamped with pros and cons lists, which is why we’re comparing the two most popular materials: uPVC and timber. Only one will come out on top as the winner, so continue reading to find out more.

Let's Get To Know uPVC

uPVC, otherwise known as unplasticised polyvinyl chloride, is a building material that first became quite popular during the 1990s. It has played a huge role in evolving the building and construction industry, as the material is well known for its low maintenance, affordability and various styles. In 2010 we saw high demand for high performing windows that looked like timber rather than uPVC, as owners of high-value homes were interested in the aesthetic appeal for less.

What Are The Advantages of uPVC Windows?

uPVC windows are the most commonly used double glazed windows for homes in the UK, and they possess a range of benefits. 

Increases the value of your property.

Helps to reduce noise (but not as good as timber).

Manufactured with energy-efficient features.

Low cost.

Low maintenance.

Storm and weatherproof.

Available in a range of styles, sizes & designs.

What Are The Disadvantages of uPVC Windows?

Although uPVC windows are ideal for homeowners, developers, and builders searching for high performance at a lower price, their disadvantages are listed below.

Poor aesthetic appeal.

Limited customisation options.

Non sustainable material.

Short life span.

What Is The Lifespan of uPVC Windows?

uPVC windows have a relatively long lifespan, but they fall behind significantly compared to timber windows.

The average lifespan for uPVC is between 16-18 years.

Let's Talk Timber

Timber windows have evolved over the years, making them more reliable, durable and long-lasting. Sticking and warping is a thing of the past with high performing engineered timber, and just like uPVC, there are many different options to choose from to meet your style and budget requirements. 

What Are The Advantages of Timber Windows?

Charming, aesthetic appearance.

Natural insulation.

Environmentally friendly & sustainable.


Increases security within the home.

Low maintenance.

Double or tripled glazing options.

What Are The Disadvantages of Timber Windows?

More expensive than uPVC windows.

The cost of timber windows will differ depending on the style and size you require. 

What Is The Lifespan of Timber Windows?

Timber windows are a worthwhile investment, as their average lifespan is 60-80 years. Over that lifespan, you can also save around 3/4s of a tonne in CO2 output.

With uPVC windows, you would need to get them replaced every 18 years, which would cost you more in the long term. Below we talk about the quality and performance of both uPVC and timber windows.
uPVC vs Timber Quality Performance

Dale Joinery is a proud member of the British Woodworking Federation (BWF). This is a dedicated body for woodworking and joinery manufacturing. Timber windows that are manufactured under the BWF are rated A+ and this is an exceptional level of performance above uPVC and aluminium windows. 

Unlike uPVC where around 50% of the material can recycled, timber is 100% recyclable. The long lifespan that timber possesses, means that it provides a clear return on investment due to their longevity, performance and value that they add to a property. 

Each type of window has different levels of quality and performance they provide.

What Do We Recommend?

Due to its natural insulating properties, its reliability, average lifespan and sustainability, we would recommend investing in timber windows. Although it’s a long term investment, and a higher one than uPVC, you’ll ultimately be cutting your energy costs down and won’t need to replace your new timber windows over your lifetime. 

However, if you are replacing windows on a budget, uPVC may be the best option for you and your home.
