Popular wooden double glazed sash window styles in the UK

Modern sash windows come in a variety of styles. Some feature a simplistic less-is-more approach while others go for more fancier ornamentation. For sash windows, wooden designs can add to the already vintage look while providing durability and recyclability. Let’s look over some of the most common designs that might inspire your home decor.

Non-bar timber sliding sash windows

Non-bar timber sliding sash window

The non-bar design is simplicity at its finest. These are potentially the easiest to glaze (among sash windows) since they consist of two glass panels uninterrupted by extra elements. This makes non-bar designs far better at bringing in light compared to other single-window designs.

Full Georgian

Full Georgian sash windows

The full Georgian sash window is styled with numerous bars between the glass. In the UK, these are among the oldest types of windows and can still be found in many buildings. In the Georgian era, it was far easier to produce small glass panes, which is why there are so many glass squares in this design. Other variants of the Georgian can have fewer bars or one of the windows with no bars (aka, the half-Georgian).

Coupled sash windows (3 window version)

Coupled sash windows

The coupled style can come in various shapes and sizes but the 3 window style is special in terms of the control over lighting and ventilation it provides to any room. With 3 points of light and/or air entry, it offers tons of utility.

Victorian true arch sash windows

Victorian true arch sash windows

The true arch window is a staple of classic Victorian-era architecture. The addition of a simple arch adds a sense of classical building design and can spruce up a traditional home concept. Some designs add to the flair by putting stained glass on the top half of the window.

Wooden box sash windows

Wooden box sash windows

Box sash windows provide the traditional look of a sash window while adding the benefits of modern thermal efficiency, noise reduction, and extra sturdiness. Windows in the UK often have to abide by certain regulatory standards and box windows can be a great replacement for outdated designs that don’t stand up to scrutiny. These are especially handy in noisy neighbourhoods.

In terms of materials, sash windows can also be divided into different types of wood.

Hardwood sash windows

Hardwood vs softwood windows

Hardwood sash windows are based on deciduous materials like mahogany, teak, and maple. These offer high durability and density (although there are exceptions to these characteristics such as balsa wood). Most hardwoods can be better for areas with extreme temperatures where other types of windows might warp.

Hardwoods will generally be 30% to 40% more expensive than softwoods. One of their main advantages is that they are more fire-resistant as well. Softwoods also tend to be more sustainable as they take less time to grow and are easier to replant.

The difference in appearance is shown mainly in the colour and texture, since hardwood windows are often with richer and a more varied grain pattern, while softwood windows usually have lighter colour and a straighter grain.

Oak sash windows

Oak is a hardwood that’s worth mentioning on its own as it is one of the most popular wooden materials. It has a notable aesthetic appeal with its distinctive grain structure and is particularly great for homes with a classical design. With high durability and a long lifespan, it can be a great investment as well-maintained oak could last over a century.

Softwood sash windows

Softwoods are often less durable and dense than hardwoods, though that doesn’t mean they are inherently inferior. In terms of aesthetic appeal, they look just as great on widows. For sash windows, softwoods can be great as they are often lighter per square metre. This can be handy if the weight of a large window is a concern. The lighter material can make them easier to open and close.

If any of these designs pique your interest and you want to get your hands on them, you’ll need quotes from a reliable installer who can ensure a job well done. Finding the right installer for the job can be a tricky task which can take days of painstaking research and price comparisons. If contacting companies on your own sounds like a chore, we can provide you with a far better alternative.

Double glazed wooden sash window cost in the UK

Double glazed wooden sash windows prices
SizeGlazingPrice
600 x 900mmDouble glazed£360 – £1,485
600 x 900mmTriple glazed£505 – £2,080
1400 x 1400mmDouble glazed£520– £1,860
1400 x 1400mmTriple glazed£755- £2,605
Sash window restoration and/or glazingDouble/triple glazed£500+

Cheap wooden sash windows can be around £360 while more upscale options can be nearly £1,860. Wooden double glazing for sash windows is standard but some may choose to opt for even higher insulation. Adding an extra layer of glazing tends to cost about 30-50% more, so triple glazed timber windows cost around £755 to £2,605.

Aside from glazing and the size of the window, the cost of installation depends on the complexity of the job. For example, replacement wooden sash windows are easier to install than swapping one window type for another. Basically, if you want replacement sash windows, the job will be easier since swapping windows requires more labour and additional parts, which drives the cost to the higher end.

If you already have the windows but want to restore or improve their thermal efficiency, this can cost upwards of £500 depending on the complexity of the job. Getting timber sash windows double glazed may not be worth it if they succumb to rot or have outlived their lifespan. In such cases, getting new wooden sash windows may be better as a long-term investment.

Pros and cons of double glazed timber sash windows

Double glazed sash windows come with a lot of benefits but also a few drawbacks that might be worth noting. While they are a great design choice, they may not be for everyone. Let’s go over why:

Advantages and disadvantages of wooden sash windows

Advantages of double glazed timber sash windows

  • Stylish: Timber windows already have a timeless look and sash designs add to that even further. Using timber for sash windows is the ideal way to maintain a classic look for vintage buildings.
  • Space-efficient: Sash windows open vertically, which means they take less up space and do not obstruct items in their vicinity. This also means you can use the window sill as an extra space for decorations or other items.
  • High thermal efficiency: Wood is a great insulator. For wooden sash windows, double glazed installations are the norm which already improves efficiency standards. This is already an advantage of timber double glazed sash windows but triple glazing can take this a step further.
  • Highly durable: Timber windows are solid and last the longest (if maintained). They can remain functional for over 60 to 80 years if you’re careful.
  • Endlessly recyclable: Wood can be recycled and repurposed with ease. This, and its ability to cut heating costs, makes it the most environmentally friendly alternative.
  • Great ventilation: With sash windows, you can adjust the height at which the window opens thus controlling the level of ventilation. They also open vertically which means they are less likely to swing open due to the wind in the same way, for example, casement windows do.
  • Suitable for homes in conservation areas: Many conservation areas will only allow sash windows since they are considered the appropriate style. Alongside the design of sash windows, timber can add even more of that classic feel.

Disadvantages of double glazed timber sash windows

  • Expensive: Wooden windows are expensive enough, but adding a sash design style can further tip the costs. While they aren’t the most costly windows on the market, they can be a considerable investment.
  • Require more maintenance: Wood can require polishing, cleaning, and general maintenance. As a material, it can succumb to rot from moisture or termite infestation if not given the right attention.
  • Harder to clean: Sash windows can be more difficult to clean since they do not open inwards. In comparison, casement windows that swing inward are far easier to wash since they allow access to both sides with ease. Although, double hung sash windows can tilt horizontally for easier cleaning, so this might be a better choice if cleaning will be an issue.

After reviewing the pros and cons, you might be considering some new windows. If you’re wondering “Where can I find wooden sash windows near me?”, we can help with that.

Are sash wooden windows something for your UK household?

Double glazed wood sash windows have an appealing, traditional look while offering a variety of designs one can fit into their home. They provide great thermal efficiency and their design inherently allows for good ventilation control. Their ability to insulate against heat loss along with their recyclability make them an eco-friendly option and one that will last for over 60 years.

At the same time, they can cost anywhere from £360 – £1,485 for the average design, which may be outside most people’s price range. On top of that, wood requires more maintenance than other materials and could succumb to rot if left around too much moisture. If these drawbacks seem minor to you, wooden sash double glazed windows may be the right option for your household.
