Bay Windows & Bow Windows

BAY WINDOWS & BOW WINDOWS – A brilliant way to add a little extra space is by replacing existing windows with our bay or bow window systems.

Bay windows

Bay windows will elegantly extend the footprint of the room slightly and add so much extra light and functionality to the room.

Bow windows

Bow windows (built out from existing walls) cleverly extend room space by adding a whole new dimension to the house.


If your customer needs some added space -now they can have it – simply by replacing their existing windows with our BAY WINDOWS and create a better view, whether they’re outside or inside.

Outside, they’ll enjoy the new updated look. Inside, they’ll notice that the room feels more spacious.

Choose from White, Woodgrain or Artisan coloured windows. Whichever option you select, being PVC-U, the windows won’t rot or lose their looks for the whole of their long life. And added thermal efficiency will also mean lower energy bills.


Bring more of the outside in with our stylish replacement PVCu BOW WINDOWS. Being built out from your existing walls, our bow windows cleverly extend the space – adding a whole new dimension to any house. While they’re clever, they are also a fairly straightforward installation option to create replacement windows with a difference.

With our choice of White, Woodgrain or 13 beautiful Artisan colours our bow window range not only delivers a wide choice of styles and colours, but also provides peace of mind, with our advanced locking system – and more peace and quiet, thanks to the sound-reducing advantages of double glazing.

We specialise in helping our trade customers to make homes more secure and more beautiful.

We achieve this by making our ‘Legend 70’ PVCu bay windows and bow windows of an exceptional standard. Our track record proves that to ‘replace’ really can be to ‘upgrade’. Our products put the elegance into energy efficiency, the style into security and a lifetime of enjoyment into high performance.

So whether your customer is looking for more of a wow factor, more security or to add more value to their home, we’ll help you achieve their aims.

Our bay windows and bow windows have achieved accreditation from the British Board of Agrément, the organisation that decides which building products are fit for purpose.

By selecting bay windows or bow windows manufactured from PVC-U rather than other alternative framing materials, you can be confident that these products will never flake, peel, rust or rot and they will provide beautiful good looks and maintenance freedom for many years to come.

Ensure that you install the most secure replacement bay windows and bow windows.

Not every replacement window system comes with the BS 7950 standard to demonstrate a superior security performance. Not all replacement doors come with PAS 24 accreditation for enhancing the security of your home. Not every replacement door comes with an optional upgrade to Police approved “Secured by Design” locking technology. Ours do.

Yale window locks as standard

Imagine a home with windows that are as long-lasting as they are beautiful – and as elegant as they are energy efficient. By replacing existing windows with our PVC-U windows, you’ll be able to make any home quieter, safer and more secure.

Green Guide A-rated Casement Windows

They’ll sense the difference too, because our windows come with a Green Guide A rating, so they’ll help to shrink energy bills. This warm feeling will last as long as their new windows. Throughout their long lifespan, they’ll remain as virtually maintenance-free, efficient and attractive as they were on day one.

So by replacing windows with windows from DCS, you can add more value to any home.
