Which Property Types Are Best for uPVC Sash Windows & Wooden Sash Windows?
Best Properties for uPVC Sash Windows
uPVC sash windows are an excellent option for modern homes or properties that need a cost-effective, energy-efficient solution. They are also a good fit for rental properties, as they offer durability and require less maintenance than wooden windows.
Furthermore, uPVC windows are ideal for homeowners who want to replicate a traditional appearance without the high cost of timber windows.
Best Properties for Wooden Sash Windows
Wooden sash windows are best suited for period homes, listed buildings, and properties that require an authentic, traditional look. If your home has a historical or heritage aesthetic, wooden windows will complement the overall style of your property.
Additionally, wooden windows are highly desirable in conservation areas and for homeowners who want to preserve the original character of their building.
Insulation & Energy Efficiency
One of the biggest concerns when replacing windows is ensuring your new windows are energy efficient. Both uPVC sash windows and wooden sash windows offer great insulation, but there are differences in their performance.
Glazing Options for uPVC and Wooden Sash Windows
| Glazing Type | uPVC Sash Windows | Wooden Sash Windows |
|---|---|---|
| Single Glazing | Typically not recommended due to poor insulation | Common in older properties; not energy efficient |
| Double Glazing | Excellent insulation and noise reduction | Great insulation, especially with low-E coatings |
| Triple Glazing | Can be added for superior energy efficiency | Less common, but can be fitted for better insulation |
| Secondary Glazing | Often used in older homes for additional insulation | Highly effective for enhancing insulation in historic buildings |
Modern glazing options such as double glazing or triple glazing can significantly improve the energy efficiency of both window types. uPVC sash windows often come with double glazing as standard, providing great insulation and keeping energy bills low.
Wooden sash windows, while often single-glazed in older homes, can be upgraded to double glazing to meet modern energy efficiency standards. Read our guide on double glazing costs to know what to expect.
Ventilation & Draughts
Both uPVC sash windows and wooden sash windows offer natural ventilation due to their sliding mechanism. However, wooden windows tend to have better natural airflow, particularly if they have been well-maintained and are not warped.
uPVC windows, while often well-sealed, can sometimes be less effective at ventilation, depending on the quality of the installation.
Security Features
Security is an essential consideration when choosing between uPVC sash windows vs wooden sash windows. Both types of sash windows can be fitted with modern security features such as multi-point locking systems and secure hinges.
However, uPVC sash windows often come with superior locking systems as standard, making them a safer option for some homeowners.
Maintenance & Longevity
When it comes to maintenance, wooden sash windows require regular upkeep to prevent issues such as rot, warping, and painting. uPVC sash windows, on the other hand, are low-maintenance, needing only occasional cleaning to keep them looking new.
| Feature | uPVC Sash Windows | Wooden Sash Windows |
|---|---|---|
| Cleaning | Low maintenance, easy to clean | Requires more care and attention |
| Wear and Tear | Durable, but may fade over time | More prone to damage but repairable |
| Longevity | Lasts 20-30 years with proper care | Lasts 30+ years with regular maintenance |
Costs & Installation
The cost of sash windows varies significantly. uPVC sash windows are generally more affordable, especially in terms of both the initial installation and long-term maintenance.
On the other hand, wooden sash windows are a more significant investment upfront but can be more cost-effective over time if maintained correctly.
| Window Type | uPVC (per window) | Wooden (per window) |
|---|---|---|
| Material Cost | £350 – £800 | £800 – £1,500 |
| Installation Cost | £200 – £500 | £300 – £800 |
| Total Cost | £550 – £1,300 | £1,100 – £2,300 |
Note: Prices of new windows will vary based on the size of the window, glazing options, and installation requirements.
Installation Requirements & Timeframe
uPVC sash windows can typically be installed faster due to their lighter weight and easier fitting process. Wooden sash windows, being heavier and more bespoke, may take longer to install and require more precision during fitting.
How to Choose Between uPVC Sash Windows vs Wooden Sash Windows
Choosing between uPVC sash windows and wooden sash windows depends on a variety of factors including budget, aesthetic preferences, energy efficiency requirements, and the age of the property. Consider the following when making your decision:
Alternative to Sash Windows
If you’re considering alternatives to sash windows, it’s worth exploring other types of windows that might be better suited to your property, preferences, and budget. One popular choice is casement windows, which offer a modern alternative to traditional sash windows.
Unlike the sliding mechanism of sash windows, casement windows open outward with a hinged frame, providing excellent ventilation and an unobstructed view. These windows are known for their energy efficiency, as they seal tightly when closed, reducing drafts and enhancing insulation.
If you’re still uncertain about which window type to choose, we’ve created a helpful guide comparing casement windows vs sash windows to help you decide which one best suits your needs.
Whether you’re looking for a traditional or modern solution, understanding the key differences between these two types of windows will allow you to make an informed decision.

FAQs
Are uPVC sash windows cheaper than wood?
Yes, uPVC sash windows are typically cheaper than wooden sash windows. The cost difference is largely due to the material and the manufacturing process. uPVC is a more affordable material compared to wood, and it requires less maintenance, which can also save money over time.
However, the initial investment for wooden sash windows may be higher due to the craftsmanship and material costs involved.
Are uPVC sash windows any good?
Yes, uPVC sash windows are a great option. They offer many benefits, including energy efficiency, low maintenance, and durability. uPVC frames are resistant to weathering, rot, and discoloration, which makes them an ideal choice for long-term performance.
They also have excellent insulation properties, helping to keep your home warm and reduce energy bills. However, they may not have the same aesthetic appeal or traditional charm as wooden sash windows.
How long do wooden sash windows last?
Wooden sash windows can last for many decades with proper care and maintenance. On average, they can last between 30 to 50 years, or even longer, depending on the quality of the wood and how well they are maintained.
Regular painting and sealing can help protect the wood from weather damage and extend the lifespan of your wooden sash windows.
