Features & Benefits

All of our bow and bay windows are manufactured using the market-leading uPVC profile from Liniar. This means that they stand at the forefront of double glazed window design, offering you standards of quality that are unmatched on the current market.

To create a seamless and authentic finish to your bow or bay windows, the external cill is welded together to create a single cill under the uPVC frame. This means that the high standards of quality are kept completely consistent across the board.

To ensure structural integrity is maintained, we can install structural bay poles through the cill to take structural loads. This is fitted onto the hidden bearing plate to ensure the aesthetic of your windows is not compromised.

Our bow and bay windows feature a range of details that allow them to achieve a period charm with a subtle modern twist. This allows you to enjoy a balance between the old and the new, bringing an addition to your home that offers more.

The high grade uPVC that is used across our bow and bay windows completely outclasses the traditional timber window design when it comes to upkeep. Our uPVC bow and bay windows will require only a wipe with a damp cloth to maintain appearance.

To ensure the aesthetic of your windows is kept consistent, we offer additional ‘dummy sashes’. This allows you to enjoy equal sightlines, whilst ensuring your windows fit the aperture that you have properly and efficiently.
