Casement Windows 

The perfect casement windows

Casement windows are incredibly versatile and come in many styles and shapes that can be configured to fit almost any home.

At Core Sash Windows, we only specialise in high-quality timber casement windows, sash windows and doors. With our extensive range of timber casement windows, you’ll be sure to find the right windows to fit your home at the right price.

What is a casement window? 

Casement windows are the most iconic style of window in the UK.

You’ll know if you have casement windows if they’re made up of two or three panes and hinged at the side rather than the top, middle or bottom.

Although they usually come in two or three-pane configurations, more panes can be added to create a new design that better suits your preferences.

Types of casement windows

There are two main types of casement windows – often known as lipped and flush casement windows. Each type can be customised in different styles and windowpane arrangements to suit your needs best.

Lipped casement windows

Lipped casement windows look just like the above shot, but the sides of the frames extend out. Both products form a robust weather seal – it’s more a question of what kind of style you prefer!

Hardwood vs softwood

Timber casement windows are constructed from either hardwoods or softwoods – each variant has its own benefits.

Although it’s almost impossible to tell the difference visually, hardwood timber casements don’t expand and contract as much compared to softwoods when the temperature changes.

However, softwoods are inherently more workable than hardwoods. Because of they’re much less rigid, they can be more easily carved and shaped to fit smaller spaces and create more complex joints.

Some examples of timber used in our casement windows are:

Hardwood

  • Oak
  • Mahogany
  • Accoya
  • Ash
  • Beech

Softwood

  • Pinus Sylvestris (aka Redwood)
  • Cedar
  • Western Red
  • Douglas Fir

Advantages of our casement windows

Timber casement windows have many advantages over their modern UPVC counterparts.

The benefits of our range of timber casement windows include:

Improved energy efficiency – Our high-quality timber and double-glazing options help better manage temperatures – preserving heat in the winter and cooling the home in the summer – saving you money.

They’re aesthetically pleasing – We only use the highest quality timber that helps give your home that highly sought-after classic look.

Practicality – Timber is inherently easier to fix than UPVC windows. When a modern plastic window is damaged, specialists often must replace the window completely, whereas timber windows can be repaired and treated to preserve them. With proper care, timber windows can comfortably outlast those made from other materials.

Security – Outdated casement windows can be prone to security problems – making them a target for thieves. Our timber casement windows are equipped with additional security features and upgraded locking mechanisms – so you can rest easy knowing you’re protected by a durable and stylish window.

Customisability – With so many options available, there’s a casement window for everyone. You can choose the number of panes, type of timber and double or acoustic glazing – letting you customise the perfect casement for your needs.

What is the difference between casement and flat casement windows? 

The only difference between casement windows and flat casement windows – otherwise known as lipped or flush windows – is the styling.

Lipped casements slightly protrude from the property and have a lower ridge across the bottom. Flat casements – or flush casement windows – stay flat to the brickwork.

Are casement windows a good idea? 

Yes, casement windows are a great idea for any home.

Not only do they look visually stylish – complementing almost any type of home, flat or apartment – they can be opened fully to allow maximum ventilation and are just as safe as the most secure windows, boasting a range of modern locking mechanisms.

Are casement windows secure? 

Casement windows are one of the most secure windows you can buy.

Because the opening handle and latches are on the inside, thieves can’t get by them without tampering with the structure itself – deterring most from even trying.

Modernised locking mechanisms – like screw locks and fasteners – can also be fitted for an extra layer of protection.

Are casement windows energy efficient? 

Yes, our timber casement windows are incredibly energy efficient.

Timber is an effective natural insulator. This locks the heat in during the winter and the cooling rooms in the summer.

With modern casements and advancements in timber quality, double glazing can be fitted, helping you save extra money on bills.

How do you measure up for a replacement casement window? 

Measuring your casement windows is easy and can be done in three simple steps.

  1. Extend the measuring tape down the entire vertical length of the casement and record the measurement.
  2. Extend the measuring tape across the horizontal width of the casement and record the result.
  3. Send the measurements off to us – we’ll handle the rest.

If you need additional assistance or just a second opinion, we’ll conduct a no-obligation survey – free of charge – to make sure everything’s in order before fitting.
