Installing double glazed windows can help turn an average house into a warm, cozy homestead. If you’re toying with the idea of getting double glazed windows, it’s best to start off with the material you want –  but who knew there’d be so many materials? 

For many homeowners, wood is the frame that trumps them all. It’s traditional, elegant, and more insulating than other options. Around 12 million windows are sold each year in the UK, with timber windows accounting for around 25% of this total.

But how many types of wood are there? How much will wooden windows end up costing you? And which companies sell them? Read on to find out everything you need to know before investing in wooden windows.

Types of wooden windows

So, you’ve managed to narrow down the list of materials to wood. Well, the good news is that you’re one step closer to a warmer, more stylish home. The bad news is that you now have to decide what type of window and wood you’d like. But that’s what we’re here to help with. 

Unlike other window material options, wooden windows are normally limited to three styles: sash, casement, and bay. Not all window companies will offer bay wooden windows, but pretty much all of them supply casement and sash windows. 

Let’s take a more in-depth look at these three main options.

Sash

What are sash windows? Sash windows have one or more movable frames, which open by sliding via a mechanism attached to the frame. 

Many people couple wood with a sash style window for their home. After all, wood and sash window frames have something in common: they’re both excellent for maintaining a traditional aesthetic charm.

Casement

What are casement windows? These windows are attached to their frame by one or more hinges at the side. Casement windows are often held open in position using a metal bar with hooks, known as a casement stay. 

This type of window gives your home a more contemporary look, while the wood feature will simultaneously maintain the traditional aura – it’s the best of both worlds!

Bay

What is a bay window? Bay windows project outward from the main walls of a home. Three or more windows usually project at 45° or 90° angles, to form a box bay window. This type of window works particularly well for smaller properties.

If you manage to find a local company that will install bay windows, it can add an extra bit of space to your home. Using wood for this style of window will also add a traditional touch to it.

So what are your options?

You have several options to choose from with wooden windows. We wish it were as simple as choosing one type of wood, but there are a few more things you need to decide on. 

The best place to start is to distinguish what category of wood you’d like. Each type of wood is split into two categories – softwood and hardwood and each one has its own set of benefits to flaunt.

What is softwood?

  • Versatile wood, available in a painted finish only
  • Much cheaper than hardwood 
  • Suits contemporary and period-style homes
  • Easier to work with various styles
  • Most popular choice: Douglas fir

What is hardwood?

  • Naturally strong, high density, durable wood 
  • More weather resistant
  • Available in both painted or stained finish
  • Generally does not require additional preservative treatments
  • Most popular choice: oak

Both options have enticing aspects, and could provide the finishing touch to your home. According to the World Wildlife Fund (WWF), despite being the cheaper option, 79% of timber windows sold in the UK are softwood frames. 

So don’t let the lower price deceive you. Something labeled as ‘cheaper’ can create the illusion of flimsy material that will break at the slightest gust of wind. Both options are brilliant, but if you’re on a budget, softwood it the option for you.

Did You Know?

You can save more than £400 each year, just by switching your home’s energy supplier. If you’re looking to cut down your bills, this one’s a bit of a no-brainer.

Cost of wooden windows

Generally, wooden windows are a nice middle-ground. They are more expensive than uPVC frames, but less expensive than aluminium. The cost of each frame will vary depending on size, but what sort of price ranges can you anticipate? 

Below, we’ve created a table to show the average prices you can expect to pay for different sizes of windows. Since sash and casement windows are the most popular styles of window (and most companies only offer a choice between them), these are the two we’ve chosen to compare.

Types of window
Measurement (mm)
Price
Casement625 x 1045£359
Casement910 x 1045£455
Casement 1195 x 1045£636

Sash630 x 1045£559

Sash1080 x 1045£728

(Costs from Travis Perkins)

As you can see, sash windows are more expensive than casement in each size. But remember – these are just averages of what you can expect. There will be lots of other factors to take into account when looking overall costs, such as:

  • Installation costs – Installation costs are added on top of the price of the window. We can’t give an exact price for this, as most installation prices will vary depending on your location, the size of the window, and whether there is any existing structural damage. 
  • Choice of wood – As mentioned above, hardwood is more expensive than softwood
  • Measurements – The bigger the window, the bigger the cost
  • Whether the windows are installed upstairs or downstairs – Second-floor installations require additional equipment, such as scaffolding, ladders, and safety harnesses. Setting up this equipment will also extend the duration of the project. 

Wooden window companies

If you’ve already started your research, you will no doubt have come across the UK’s many window suppliers. However, not all of these supply wooden windows. 

Below, we’ve listed the four main national window installers in the UK. You can check out which companies supply wooden windows below:

Installer
Wooden windows
uPVC windows
Aluminium windows
Anglian Home ImprovementsYesYesYes
EverestYesYesYes
Safestyle UKNoYesNo
Zenith Home ImprovementsNoYesNo

Anglian and Everest are both excellent installers to go with. That said, for us, Anglian is just one step ahead in this war of the windows. Why? Well, they install wooden frames for casement, sash, cottage, bay, and flush windows. Everest, on the other hand, can only do casement and sash, similar to many other installers. 

But you’re not just limited to these national companies – you can also go local. To give you an idea of what to expect, we’ve collated the best local window installers in the UK’s major cities:

Wooden vs other types of windows 

Let’s get straight to the point – wooden windows cost more than uPVC (the UK’s most popular choice of window material). But what they lack in sheer affordability, they gain in demonstrable quality. 

There are a number of benefits to choosing wood over plastic – particularly wood’s eco-friendliness. If dealt with appropriately, wooden window frames can be totally renewable, meaning they can be recycled or reused properly if they need replacing. And yes, uPVC is cheaper, but it consists of 43% non-renewable materials. Just think of your carbon footprint!

But what other advantages do wooden windows offer? Check them out below:

How long do wooden windows last?

Wooden windows have an estimated lifespan of 60 years! That’s right – 60 long, healthy years. By contrast, uPVC has an estimated lifespan of just 30 years, so it’s worth figuring out whether you can afford to fork out a few more pennies now to save more in the long run.
