UPVC vs Timber Windows: Which is the Best Option for Your Home?

January 8, 2024

Choosing the right material for your upgraded windows is crucial. UPVC and timber windows each come with their own set of advantages and disadvantages, so it’s essential to thoroughly evaluate them before making a decision. In this article, we’ll compare UPVC and timber windows to assist you in making an informed choice for your home.

Comparing UPVC and Timber Windows UPVC windows are a popular option among Irish homeowners due to their perceived affordability and suitability for double glazing. However, before dismissing timber windows, it’s important to consider whether these factors hold true or if there are other aspects you should take into account. Explore the comparison below to guide your decision-making process.


If you’re constrained by a tight budget, UPVC windows present a more affordable option in the short run. Conversely, while timber windows entail higher initial costs, the overall expenses tend to even out over the long term.


UPVC requires minimal maintenance, but it may discolor and become brittle over time, eventually necessitating complete replacement. On the other hand, high-quality timber windows only require a brief coat of paint every 7-10 years to stay well-maintained.


UPVC windows typically last between 15-20 years before they need replacing, whereas well-maintained timber windows can last up to 70 years or more.


Fitting double glazing within the UPVC window frames will keep your home well-insulated and offer good noise cancellation. Timber is a naturally insulating material that provides better performance than UPVC.


While UPVC windows provide a variety of style options, including faux wood grain, they can pose a significant threat to property values in conservation areas. In contrast, timber windows have the potential to enhance “curb appeal,” with 82% of estate agents believing that original features contribute value to period properties.

Environmentally friendly

UPVC frames, composed mainly of plastic and metal, pose challenges in recycling and often end up in landfills. In contrast, timber windows utilize organic materials that are not only more sustainable but, with proper maintenance, also have a significantly longer lifespan.

In conclusion, UPVC has its merits, such as being cost-effective, robust, and providing good insulation. However, these advantages are more geared towards short-term gains, and in the long run, they can become a more costly option. For example, UPVC windows have a lifespan of just a third compared to timber windows, requiring earlier replacements. Moreover, they may adversely affect the value of your home, especially if it’s a period property. On the other hand, timber windows can endure for 70 years or more and have a more positive environmental impact.

While UPVC windows may seem economically favorable initially, timber windows prove to be a more enduring, energy-efficient, and environmentally friendly choice. With proper upkeep, they offer a longer lifespan and contribute to the visual appeal of your home. Therefore, if you’re aiming for a lasting investment, timber windows are the preferable option.
