Common questions

What exactly is a flush casement window?

This style of window fixes to the frame using side hinges to facilitate opening and closing. There are two options available: single or paired windows. Either of these can be fitted into the frame, due to the external hinges. To let in as much air and light, your windows will open outward.

Alternatively, your units can be top hung. This is a less common method and is sometimes referred to as an awning casement window. As its name implies, the hinge sits at the top, which helps keep out the rain (an ideal choice if you live in a colder climate). Should you live in a basement, a bottom hung (or hopper) window is best.

Need some technical advice? We’d be glad to talk you through the pros and cons, so you can make a more informed decision before committing.

Casement and picture windows: What’s the difference?

Because a flush casement window bonds to the frame using a hinge, it can swing in or out. This means you’ll have little trouble ventilating your rooms. Picture windows are designed to create stunning views of the outdoors, reinforcing a stronger sense of connection between your interior and exterior spaces. To be able to do this, they have thinner frames and no hinges, meaning they cannot be opened.

We frequently fit flush casement windows in Cornwall, Redruth, and locally.

What do flush casement windows cost?

As with all of our windows, the price will vary. That’s because we offer a range of colour, hardware, glazing, and finishing options. We’ll work closely with you to recommend the right design, at which point we’ll propose a cost. 

Our casement windows are suitable for homes, conservatories, orangeries, and house extensions, so tell us more about your home improvement objectives when getting in touch. That way, we can tailor a solution to suit your needs and budget.

How energy efficient are flush casement windows?

Our units are fully sealed, thanks to the airtight seal which naturally forms when the sash presses against the closed frame. This creates an essential barrier that prevents cold air from getting inside your home. It also stops warm air from escaping, insulating your property and lowering your energy costs at the same time. You won’t even need to crank up the thermostat to keep cosy.

To get the most out of your installation, we’d recommend double or triple glazing for your windows. This won’t just shrink your heating bills; it will also reduce noise pollution, a welcome benefit if you live in a built-up area with lots of footfall and traffic.

How secure will my units be?

Your installation will feature a dedicated hook-shaped lock that integrates with the frame, making it almost impossible to gain access from the outside. Even the most determined intruder will struggle, thanks to the multi-point locking system included as standard, which adds a further level of protection.

We’re proud that our casement windows have made our customers’ homes in Cornwall, Redruth, and the surrounding areas, a lot safer. Each one meets the criteria : a UK police initiative designed to lower burglary rates countrywide. Keep your loved ones safer and enjoy peace of mind by contacting us to

Are your flush casement windows really worth the investment?

More light, more air, a better sense of space – and a home that’s more secure. These are just a few of the benefits you’ll enjoy when you put your trust in Atlantic Windows. Every one of our products features compression seal technology that sits flush with the sash, preventing the ingress of cold air and keeping heat inside.

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.
