Comparing the Appearance of Timber and uPVC Windows

One of the primary factors homeowners consider when choosing windows is their aesthetic appeal. Timber windows exude a timeless charm, adding a touch of elegance to any home. The natural grain patterns and warm tones of timber create a classic look that many homeowners find appealing.

On the other hand, uPVC windows offer a sleek, modern appearance. They come in a variety of colours and finishes, allowing homeowners to choose a style that complements their home’s design. The choice between timber and uPVC ultimately depends on your personal preference and the overall look you want to achieve for your home.

Energy Efficiency: Timber vs uPVC Windows

Energy efficiency is a significant concern for homeowners, as it not only helps reduce utility bills but also contributes to environmental conservation. When comparing timber and uPVC windows in terms of energy efficiency, uPVC windows have the upper hand. uPVC windows are inherently better at insulating your home, helping maintain a consistent indoor temperature.

They are designed to prevent drafts and heat loss, making them an excellent choice for energy-conscious homeowners. Timber windows, while providing some insulation, may require additional measures to achieve the same level of energy efficiency as uPVC windows.

Maintenance Differences Between Timber and uPVC Windows

Maintenance is another crucial aspect to consider when choosing windows. Timber windows require regular maintenance, including painting or staining, to protect them from the elements. If not properly maintained, timber windows can deteriorate over time, leading to costly repairs or replacements.

On the other hand, uPVC windows are low-maintenance. They do not require painting or staining and can be easily cleaned with soapy water. Their durable material ensures that they do not rot, warp, or corrode, making them a hassle-free option for homeowners with busy lifestyles.

Exploring Finish Options: uPVC vs Timber Windows

When it comes to finishing options, both uPVC and timber windows offer a range of choices. uPVC windows come in various colours and finishes, allowing homeowners to customize their windows according to their preferences. Whether you prefer a classic white finish or a bold, contemporary colour, uPVC windows can be tailored to match your style.

Timber windows, on the other hand, offer the versatility of different wood types and finishes. From oak to pine, homeowners can choose a timber variety that complements their interior and exterior decor. The finish options for both uPVC and timber windows are extensive, giving homeowners the freedom to express their creativity.

Cost Comparison: Timber vs uPVC Windows

Cost is often a decisive factor for homeowners when choosing windows for their homes. In general, uPVC windows are more budget-friendly than timber windows. The initial cost of uPVC windows is lower, making them an attractive option for homeowners with limited budgets.

Additionally, uPVC windows require less maintenance over the years, saving homeowners money in the long run. Timber windows, while offering a luxurious and traditional feel, come with a higher initial price tag. However, some homeowners are willing to invest in timber windows for their aesthetic appeal and classic charm.

UPVC vs. Wood: Pros & Cons

UPVC windows:


  • Cost – Opting for UPVC is the most economical choice if you’re working with a tight budget, as it comes with substantially lower installation and maintenance costs compared to alternative window materials.
  • Insulating Qualities – UPVC frames can offer excellent insulation, although it’s essential to note that not all window profiles provide the same level of insulation. At First Home Improvements, we utilize a profile with five separate chambers, establishing multiple barriers that effectively minimize heat transfer from the outside to the inside, ensuring superior insulation against cold weather.
  • Upkeep – UPVC windows offer a pristine appearance with minimal effort, fulfilling our desire for hassle-free maintenance. Keeping them looking as good as new requires an occasional wipe-down with soapy water.
  • Longevity – UPVC’s non-corrosive nature eliminates concerns about rot or rust, ensuring lasting durability. Unlike other window materials, UPVC windows are resistant to fading even when exposed to prolonged sunlight.
  • Lifespan  – UPVC windows typically have a lifespan ranging from 10 to 35 years, a duration influenced by both the quality of the material and the level of maintenance they receive.


  • Aesthetic Appeal – While UPVC windows are available in diverse colours and designs, some might argue that they lack the charm and captivating appearance that wooden windows effortlessly exude.
  • Personalization – UPVC windows have limitations in terms of standard colour choices. Nevertheless, First Home Improvements offers a solution by providing a service to spray your windows in any RAL colour before installation, at an additional cost. In contrast, wooden windows offer greater flexibility, allowing the application of paint and varnish in any desired colour. This versatility enables you to create a distinct appearance that can be easily altered if preferences change.

Wooden Windows:


  • Appearance – Achieving the timeless charm of traditional wooden windows is a challenge for other window materials. Wooden windows possess unparalleled aesthetics and are highly versatile and customizable to suit individual preferences and architectural styles.
  • Improved Insulation – Wooden windows offer excellent insulation properties, effectively minimizing the transfer of heat or cold into your home.
  • Longevity – Wood has the potential to outlast many other frame materials significantly, but this longevity is contingent upon diligent and appropriate maintenance practices.


  • Upkeep – One drawback of wooden windows is the need for meticulous maintenance to preserve their excellent condition. This entails regular applications of new paint or treatments to prevent decay, often necessitating annual attention.
  • Susceptible to Insects – Wood, if not properly cared for, can be attractive to pests like termites and carpenter bees, posing a potential issue for homeowners.

If you value a traditional, elegant look and are willing to invest in regular maintenance, timber windows might be the right choice for you. On the other hand, if you prioritize energy efficiency, low maintenance, and budget considerations, uPVC windows offer a practical and cost-effective solution. Consider your specific needs and weigh the pros and cons of each material to make an informed decision that suits your home and lifestyle.

My technician Andrew replaced all my sash windows that had rotten sills. Accessing the rotten sills was not an easy task. He explained to me what needed to be done in order to fix the problem. He is a great person and I’m happy that he was the one who did the job. He is reliable, tidy, friendly and very professional. I highly recommend him.



I hired Andrew and Alex a while back to repair my damaged sash windows. They were was very considerate and very patient as he did his job. A few days ago, I had another problem with one of my sash lock keys and I called him again to come and fix the problem. I’m very impressed that Liam responded quickly and he not only fixed the problem but he also gave me a spare key. What a great after sales service!

I’m very impressed with the new windows that Andrew installed and also the reconditioning job that he did on other sash windows. The quality of his work is by far more superior than what we got when we hired another company a few years back. We will certainly hire him again if any window work arises

Alex did a great job in fixing windows in our terraced house. The windows were broken, frames damaged and the wood was also rotten. Alex's job was high quality and he did it pretty fast. I was also very impressed that he was considerate of my son’s asthma condition and maintained cleanliness. Top work.



Andrew just recently replaced three sash windows in my Edwardian house. He also repaired and replaced some sills and draught proofed three windows. In addition to that, he also did some carpentry work. What I like the most about Liam is that he did a clean job. He is very professional and always updated me about the timescales and costs. He also did his job with minimal disruptions. I highly recommend him.
