Bow Windows

Bow windows are designed to create a smooth curved appearance, using four to five identical windows. These are usually fitted at a 10-degree angle to create the curved effect they are known for. Bow windows are perfect for bringing a great amount of light into a room, which is why they are a common choice for living rooms. Not only does this make the room appear larger in size but it also allows more daylight to enter the home. Increased daylight in your home can help with several other benefits including a better mood and increased productivity.

Types of Bow Windows


Bow windows are versatile and available in our range of casement windows in both PVC and aluminium. You can customise your bow windows to suit your exact taste with your choice of finish and colour. Our bow windows are made to measure at our production facility in Brighouse and we can therefore offer bespoke sizes with various options available when it comes to finishing touches.

Bow Window Styles

Whether you choose a fixed frame, classic side hung or top hung window style your home will benefit from enhanced views and increased natural light. Bow windows are only available in our classic casement window style in your choice of PVC or aluminium.

Bow Window Design

As well as brightening the room – the multiple windows that make up a bow window offer panoramic views. Due to their curved appearance, double glazed bow windows add a bright and spacious feel wherever they are installed. Bow windows are a traditional window option and we have design options available to create Georgian bow windows with grids in your choice of finish and colour.

Bow Window Installation

The frames used in the construction of the bow window are fully reinforced and connected using corner posts. The external sill is welded together to create a continuous sill that runs underneath all the window frames. It is possible to replace an existing flat window with a new bow window or even expand the aperture to create an opening for a wide bow window. If you decide to go down this route, please be aware that a new roof above the bow window section is required.
