Bay Window Replacement Specialists


Windows for bay openings need to do more than simply look good. They must be carefully manufactured and installed to suit the angles, structure, and character of the property while delivering excellent energy efficiency, security, and long-term performance. Whether replacing tired old timber frames or upgrading outdated double glazing, modern windows for bays can completely refresh both the appearance and comfort of a home.


At Prior Products, we manufacture and install high-quality uPVC and aluminium windows designed specifically for bay configurations. From traditional Victorian and Edwardian bays to more modern styles, we can create made-to-measure solutions that maintain the original character of the property while improving insulation, reducing maintenance, and enhancing natural light.


With a wide choice of colours, glazing options, and decorative finishes available, every installation is tailored to suit the home and fitted by our experienced local team.

Key Features of Bay Windows


Bay windows are made up of multiple window sections joined together to project out from the wall of the property. Common designs include three-sided and curved configurations, creating a wider external view and a more spacious feel inside. Available in uPVC, aluminium, and timber styles, bay windows can be tailored with different glazing, colours, and finishes to suit the character of the home.

What's the Difference Between Bay and Bow Windows

Bay and bow windows both project out from the main wall of the home, bringing in more natural light and creating a wider outlook.


The difference is mainly in the shape. A bay window is usually made up of three sections, with a larger central window and two angled side windows, giving it a more defined, angular shape.


A bow window is normally made from four or more window sections set into a gentler curve, creating a rounded appearance across the front of the property.


Both styles are traditional features, often found on period and character homes, and the right choice usually depends on the existing shape of the opening, the age of the property, and the look you want to preserve.


For modern properties, a bay window with squared corners usually works best.

Adding a Bay Window

A bay window can often be added to a property by extending outward from an existing flat window opening, creating a deeper internal window board and a more open feel inside the room.


The original opening remains the same size, with the new bay structure projecting externally from the wall and being supported underneath by decorative load-bearing brackets fixed to the outside of the property.


A small canopy or tiled roof is then added above to complete the look and protect the installation from the weather. This style of bay installation is a popular way to add character, extra light, and a traditional feature to the home without major structural alteration to the original opening.


Adding a bay while creating additional floor space would require a lintel and building work. You may also need planning permission.

Casement Windows for Bay and Bow Windows

Casement windows are one of the most popular choices for bay window installations thanks to their versatility, clean appearance, and excellent ventilation.


They can be configured to suit the angles and shape of almost any bay, whether traditional or modern, while providing wide opening sections for airflow and easy operation. Modern casement windows also offer excellent thermal efficiency, secure multi-point locking systems, and low maintenance performance, making them a practical choice for homeowners looking to improve both comfort and appearance without losing the character of the bay.


You can replace sash windows with casement windows if you prefer. We'll help you make the right choice and are happy to quote for both. Things to consider, as well as style, are how easy they are to access, whether they open onto a path and the way you like to experience air flow. 

Sash Windows for Bay Windows

Sash windows and bay openings have long been associated with some of Britain’s most characterful homes, from elegant Georgian townhouses to Victorian and Edwardian properties.


The combination works beautifully because the vertical lines of sliding sash windows naturally complement the shape and proportions of a bay, helping to create a balanced, timeless appearance both inside and out.


Beyond their traditional charm, modern sash windows offer smooth operation, improved insulation, enhanced security, and reduced maintenance, allowing homeowners to retain the classic look of their bay while enjoying modern performance and comfort.

High-Quality Composite Doors

STRENGTH

Our composite doors offers a truly appealing entrance for any home, with a high definition smooth or grained GRP outer skin that will look stunning for years to come.


The door offers stability from the elements with its inner core of LVL encased with composite stiles and rails for protection against any water ingress. Our doors usually have a grained PVC edge to the hinge and lock side in either White, Chartwell Green, Anthracite Grey, stain or paint finish.

SECURITY

We take security very seriously. Our composite door comes security features which stand up to current and future security standards, including PAS 24 in line with Approved Document Q.



We recommend the use of multipoint locks (locks should always be engaged so the door is not left just on the latch) and security hardware including TS007 high security cylinders and handle combinations and TS008 letterplates.


COLOUR

With our high-performance paint technology and three state-of-the-art, in-house paint lines, we can offer any colour door that can even complement the colour options on frames. This provides a fantastic choice for the homeowner. In most cases the doors come in white as standard on the internal side, however we may be able to offer different or bespoke options to suit your individual requirements.


See our colour ranges for more information

GLASS AND GLAZING

The visual impact of your door is enhanced by your choice of glass. Depending on the style, the units will be either a double or triple glazed.



The FLiP glazing cassette system is re-glazeable and offers superior performance and aesthetics. As well as passing PAS 24:2016 security attack tests.


Frequently Asked Questions about Composite Doors

  • What is a Bay Window?

    A bay window is a window arrangement that projects outward from the main wall of a property, creating extra space inside the room and allowing more natural light to enter from different angles. 


    Unlike a flat window that sits flush with the wall, a bay extends externally to form a feature on the outside of the home while creating a wider window sill and a more open feel indoors.


    Bay windows are commonly found on Victorian, Edwardian, and traditional British homes, although they are also used on modern properties. They are usually made up of three sections with angled sides, while some designs use additional window panels to create a softer curved appearance known as a bow window. Bay windows can be fitted with a range of styles including casement windows, sash windows, and fixed glazed sections depending on the look and functionality required.
