Double Glazed Windows

We install high-quality double glazed windows throughout Cornwall, Redruth, and the local areas. Each one is tailor-made at our dedicated factory, so you won’t need to compromise when you choose Atlantic as your installer.

Our energy-efficient windows meet the highest standards. We only use A+ rated glass for your peace of mind and you can opt for double or triple glazing, depending on your preference. Not sure which one is right? We’d be happy to advise you further.

We invest in the best PVCu, too. This material has come a long way since the 80s. It combines a thermally efficient design, with style – you can now choose from a variety of wood finishes and colours. If PVCu isn’t for you, then explore our range of aluminium windows, which are bound to add a touch of charm to any home in the Cornwall or Redruth area.

Investing in new double or triple glazing is a big deal. You want to be sure you’re making a cost-efficient choice. We’ll spend as much time as needed to put your mind at rest, so you can be sure you’ve selected the right options for your home.

Common questions

How do I choose the best frame?

There are many factors to consider. The size of your budget and the type of home you live in will determine the types of frames best suitable. 


Timber frames are authentic and well-suited to homes in heritage sites. But, they are more expensive than other types and tend to warp in response to temperature fluctuations.


uPVC is ideal if you have a limited budget. Many of our customers choose uPVC windows for their homes in Cornwall, Redruth, or the surrounding areas. It comes in an array of finishes, including wood, so you won’t need to sacrifice style for performance.


Aluminium is more expensive than timber or uPVC. That said, it is stronger and longer-lasting. Less aluminium is needed to provide strength, which means your units will feature less frame and more glass (resulting in better views).

Will I save money by updating my windows?

Depending on what you had previously, you should notice a reduction in your energy bills. The saving will vary depending on whether you choose double or triple glazing. But either of these will make a difference if your existing units are old and have inefficient seals that let in lots of cold air. By upgrading, you won’t need to worry about draughts slipping through and making your installations less thermally efficient.

If your existing units are single glazed, you’ll notice the biggest difference in terms of cost and comfort.

Can my windows be designed to match my property style?

Your home should be consistent throughout. Installing units that clash with your existing look will devalue your property and make spending time in it less enjoyable. With extensive experience of fitting windows throughout Cornwall, we’ll help you choose the right colours, styles, and finishes.

Which glazing should I choose for my home?

The popular choice for homeowners throughout the UK continues to be double glazing. Quality inevitably varies, depending on the manufacturer and the installer chosen to complete the work. In our experience, a 28mm unit with a 20mm gap between the panes produces optimal thermal efficiency (and sound reduction). That’s why we offer it as standard with all new installations.

Do you reside in an area that is often cold and damp? If so, don’t settle for less. Enjoy the best thermal efficiency available by asking about our triple glazing. It features three glazed panes, two gaps, and is ideal for homes in rural areas.

What warranty do you offer?

Our window warranties include a written guarantee valid for up to 10 years. This means that you can buy our high-quality products without worrying about replacing them in the near future. 

Our installations often exceed their recommended lifespan, so your property will look good and perform well for much longer than you expected. We’ll also show you how to get more from your double or triple glazing.

We value customer service and will fully support you from the moment you contact us, through to the point of installation and beyond.

Do I really need to upgrade?

You could always repair them. But if your units are no longer performing, it may be more cost-effective to replace them with more thermally efficient versions.

If you’re not sure whether your windows need replacing, here are some tell-tale signs to look out for:

  • You struggle to open or close them
  • Glass is often covered in condensation
  • The frames are clearly degrading
  • The glazing feels cold when you touch it

If the answer to one or more of these yes, then it’s time to think about replacing your units.
