What Are Casement Windows?

Casement windows are a classic choice when you’re looking for a sturdy, easy-to-use, and stylish window. They open symmetrically on hinges and can therefore be hung so that they open to any side of a building. Whether you want one in your living room or an attic bedroom, casements are commonly used all over the world.

Why Choose Casement Windows?

Updating the look and feel of your home with new windows is one of the best ways to transform your indoor environment. Your casement windows make it easy for you to get fresh air and natural light into any room, and they can also be made to fit with any contemporary or traditional decor. Here are some of the reasons why casement windows are popular with homeowners across London.

Low maintenance

You spend less time on home maintenance with casement windows, there are fewer moving parts to maintain and casement windows do not need to be painted.


Casement windows offer a high level of safety. Casement systems use interior hinges and glass seals to eliminate exposed moving parts, thus eliminating any potential for injury. Ace Glazing installs the highest quality casement products in your home. Our efforts ensure top quality installations with no compromises in safety – or style. Durability

Good for Ventilation

Good for lower air conditioning bills, Casement windows are one of the most useful styles to have around because they offer easy ventilation.  Due to their crank-style hinges, casement windows are opened from the bottom sash, offering a type of opening alternative to the traditional top-hinged window. The design of casements allows them to be used in small rooms where gable windows or fixed windows might not function properly. Casement windows will open from either side on only one hinge, so they can be set between two walls; this is a great idea when space is tight and you still want fresh air.

Thermal Efficiency

Thermal efficiency for a casement window is far superior to that of a sliding or hinged window design. Thanks to the simple fact that the header frame stays in the same position throughout the open/close cycle, this feature eliminates numerous common issues that people who use sliding and hinged windows encounter year after year, such as water leakage and rattling during window operation.

Aesthetically Versatile

Casement windows come in many different sizes and shapes as well as add a touch of class to traditional or modern homes. Casement windows also provide an excellent source of light because they swing outward as they open, allowing for maximum natural sunlight to shine through.  Call Ace Glazing London today on 020 452 51670 to get a free no obligation quote for your home improvement to enjoy these bountiful benefits.

Our Casement Windows Material Options

Our Casement windows are available in an array of materials with varying benefits and characteristics. Choose from popular options like aluminium, timber and uPVC to match your property.


uPVC casement windows from Ace Glazing are available in the following finishes: Anthracite, Light Grey, Union Jack White, and Bronze. Available in a range of colours and with Low E glass to help draft proof your home.


Timber is a classic choice for casement windows. Beautifully crafted, timber windows enhance your home with their timeless good looks and feel.


Aluminum is the most commonly used Casement Window Material. Aluminum has a great strength to weight ratio, corrosion resistance, and is well suited for damp or temperate climates. It is also relatively easy to work with casement windows that are custom-built of aluminum casement window frames or cost more per square foot and last longer than steel when compared to other materials.

Casement Windows Styles We Offer

At Ace Glazing London, we take pride in our casement windows. We offer a variety of styles to meet your needs. Each style is made from the best materials. Below are some of our popular casement window styles.

Single Frame Casement Windows

Single frameless casement windows are designed with a single pane of glass and no metal surrounding the glass. This design lets in lots of light and is visually appealing from the inside. These windows can be opened to give plenty of ventilation in warmer climates, or closed for insulation and protection from moisture. We offer a wide range of colours to match your home’s decor.

French Casement Windows

Our Casement Windows are an ideal choice if you are looking for a window that offers both style and practicality. Our French casement windows include louver styles, which let in an abundance of natural light. Our carefully designed systems can be fitted to provide secure ventilation as well as a classic bay or sash effect, all available within our modern-day products.

Double Frame Casement Windows

Easy to operate and extremely durable, the Ace London double-frame casement window is the perfect choice for your home. The convenient sliding side panel allows you to easily reach in to open or close the window, while the double-frame construction adds rigidity and strength to this one-of-a-kind product. The unique double frame casement design comes with an energy efficient triple glazed unit. The windows have a class 5 contact rating, which means the rated U value is 0.47W/m2K, keeping the heat and cold outside where it belongs.

A performance enhancing Argon Gas fill improves efficiency by around 400 times compared to normal air filled glazed units.

Push-out Casement Windows

Our push-out casement windows offer the same classic design advantages of a traditional casement window with the added benefit of increased accessibility and ease of operation.

Glazing Options Available

Some of our other glazing glass options are highlighted below.

Toughened glass or laminated glass

All of our casement windows and doors come with toughened or laminated glass and are fitted with lightweight aluminium frames. They can be double glazed with either argon (green) gas-filled or low emissivity (low e) glass, giving excellent thermal insulation properties.

Acoustic glass

Acoustic glass is a new addition as one of the many glass options for Ace range of casement windows. Acoustic glass is economical and has a high sound absorption rating throughout the bass through to treble ranges when installed in conjunction with Ace acoustically efficient frames using Polypropylene or PVC door profiles. Critical inclusions are the elimination of all voids between frames and profiles on most glazing options, along with edge spacer blocks results in significantly reduced sound transmission allowing for easier noise filtration during construction.

 Obscured or textured glass

The Obscured glass option on our casement windows provides the privacy that obscures the view from the outside, allowing occupants to see out whilst maintaining peace of mind. The textured finish is achieved using a luxurious Velvet finish and allows you to create a premium look while making sure the glass does not obstruct your stunning vista.

Stained glass

Need a little touch of class? Think stained glass – an affordable, elegant way to give your home some flair. Stained glass lets the light shine through. At Ace, we create custom framed stained glass that is designed by you. With a wide variety of options, we have something for every room in your house.

Weather-Sealing Double Action Gaskets

Weather-sealing has never been better. Our insulation system keeps cold weather out, warmed air in, and heat loss to a minimum.

This means draughts are kept out and heat remains in.  Call us today on 020 452 51670 to get a free no obligation quote for your casement window installation or replacement to enjoy these unique features from Ace Glazing London.

How expensive are casement windows?
The cost of casement windows depends largely on the size and style you choose. On average, they’re about £1,000 more expensive than a standard double-glazed unit window replacement. In some cases, they might be higher or lower than this figure.
Can casement windows be installed sideways?
Yes, casement windows can be installed sideways. Casements are a type of sash window that opens by pivoting 90 degrees on one side inwards. Aesthetically, it makes a huge difference if you install them in a different way than the conventional style.
How long does it take to have my windows installed and replaced?
Within 5-7 days of ordering your windows, your new windows will be installed and the old ones removed. If you are a larger commercial establishment it’s best to order 4 weeks before you require the installation.
I live in a listed building and/or conservation area, are you able to work on my windows?
Yes. We work on listed buildings and local authorities are happy to work with us as our techniques are non-destructive.
Can you match the style of my existing windows?
Yes, casement windows are available in a wide range of styles from traditional and modern to sleek Scandinavian. Their versatility makes them ideal for any house.
Are your windows compliant with building regulations?
Yes, all our windows and doors are compliant with consumer protection legislation. All Ace glazing products have a comprehensive 10-year guarantee that provides peace of mind for you and your home.
Is it cheaper to repair or replace?
It can be tricky to tell whether you should repair or replace, but ultimately it depends on the cost of repairs compared to the new replacement. At Ace Glazing, we try our best to work with you and your budget.
