Casement Windows

  • Effortless elegance characterises every one of our casement windows. This versatile range features double or triple glazing that bonds to a frame by way of hinges that can open inward or outward. It is also possible to bottom or top hang this style.


    In the case of top hung casement windows, they are operated from the top but open from the bottom of the frame. This means they excel at keeping out the rain, leaving your rooms dry and well ventilated. By adjusting the angle of your window you can let in more or less breeze, depending on your preference.

    Casement windows are popular with our customers, who like being able to tailor the appearance and performance of their new double or triple glazing. Each one is bespoke-built at our state-of-the-art premises and thoroughly quality checked before being delivered to your home for installation.

    A choice of frames, colours, hardware, and accessories is available to ensure your windows fully reflect your personality.

Common questions

What is a casement window?

It’s a versatile window style that attaches to the outer frame of a window via a sash using hinges sited within a groove. This means the hinges cannot be seen when viewing the window from outside.

Casement windows can be single, paired or of any other variety. Any of these types will sit within the frame and will open outward. Protection from gusts of winds is delivered via dedicated friction hinges.

The most common choice is side-hinged but you can opt for top hung. This means the hinge will sit at the top of the frame. The handle will be at the bottom. This method is often used in kitchens and bathrooms for ease of access. Top hung casement windows also block out water created by rainfall. Need one for a basement room? We’ve got that covered too. It’s known as a bottom hung window.

Casement window summary:

  • Euro groove hides hinges when viewing window externally
  • Egress hinges for upper rooms to create fire escapes
  • Friction hinges that open to 60/90 degrees
  • Incredibly versatile window designs. 
  • Two hinges fitted to the side

Are casement windows more energy efficient?

Units are completely sealed to form an airtight seal when the window sash presses against the frame. This means cold air is unable to find its way in, keeping the interior of the home warm.

To improve thermal efficiency, triple glaze your windows and watch your energy bills drop even further.

How are casement windows and picture windows different?

Because casement windows affix to the frame by way of a hinge, they swing out in an arc. This introduces cooling breezes that circulate to make a home feel cooler while preventing damp or mould. Picture windows cannot be opened but are extensively glazed, resulting in stunning views of the outdoors.

Are casement windows extremely secure?

This style of window is difficult to bypass, due to special hook-shaped locks that insert into its frame. The inclusion of a state-of-the-art locking mechanism serves to further deter intruders. 

We professionally install our casement windows, which meet criteria in full. This means you can use Atlantic Windows with confidence, knowing your family will be better protected.

How much do casement windows cost?

Cost varies depending on the materials used, the size of the window, and what hardware, accessories, colour-schemes, and finishes are chosen. Contact us for more information and a free no-obligation quote.

We refuse to compromise on quality

Our windows are made from British Made, high quality MarinespecTM components, with up to 25 years anti corrosion. They are built specifically for the more exposed areas of corrosion, such as coastal environments to give you worry free performance beyond your guarantee.  We believe spending more on components is worth every penny, and sets us apart from our competitors.

State of the art fabrication for best quality

We have invested millions of pounds into one of the most state of the art manufacturing facilities in the UK.  This enables us to provide you with consistently high quality products at exceptionally good prices. Our loyal factory workers are well trained and take pride in their work, they really care about quality.  Our machines are maintained according to a rigorous servicing regime to keep them in top condition.

Superior energy efficiency

Our ‘A’ rated energy efficient and triple glazed windows are tested by the BFRC, which will save you money on your heating bills. By law your windows and doors have to meet strict thermal performance regulations but you can be rest assured that our products exceed current requirements.

Energy saving is incredibly important and so is keeping your fuel bills down. We are continuously looking for ways to make our homes energy efficient and one way is to choose new PVCu windows and doors. Not only will they help to keep your home warmer, they will reduce your energy loss.

Don’t just take our word for it!

Our suppliers conform to strictly controlled and independently monitored Quality Management Systems such as ISO 9001, to ensure that everything is done correctly and according to best practise.

Our windows are tested independently by British Standards for security, weather tightness and strength performance. This means that periodically, we have to send them to independent test houses, in order to be tested to destruction.

These are just some of the many standards the products in our vast range conform to. Needless to say we take the quality of our products very seriously indeed.
