Although the terms are sometimes used interchangeably, bay and bow windows have different structures. A bay window projects outwards from the external wall and usually consists of three sections. A larger central window is commonly positioned between two angled side windows. Other configurations are possible depending on the dimensions and design of the property. Bay windows create a defined projection from the building and can provide useful additional internal space.
A bow window uses several window sections arranged to form a shallower curve. Four, five or more sections can be combined depending on the required width and projection. The multiple glazed sections give a bow window its characteristic curved appearance and provide a broad view from inside the room. South Lakes Windows can advise on the most suitable configuration if you are replacing an existing installation. Where a homeowner wants to create a new bay or bow window, additional structural considerations may apply and these can be assessed as part of the project.
Older bay windows can become a significant source of heat loss if the frames, glazing or seals no longer perform effectively. Draughts, condensation between panes, difficult opening mechanisms and deterioration around the frames are common reasons for considering replacement.
Our replacement bay windows are manufactured to suit the dimensions and angles of the existing opening. Careful surveying is particularly important because a bay is made from several individual window units that must work together as one structure. Customers can select modern UPVC windows for low maintenance and good thermal performance, while timber provides an appropriate option for many traditional and period properties. Aluminium may also suit projects where slimmer frame sections and larger areas of glass are required. The individual windows within the bay do not all need to open in the same way. Fixed panes can be combined with opening casements to provide the required balance between ventilation, views and security.
Where the existing bay forms part of the structure supporting the building above, suitable structural support must be maintained during replacement. Our team will assess the existing installation and determine the requirements before work begins.
A bow window can provide an alternative where homeowners want a broader glazed feature with a softer projection from the property. Because a bow consists of several individual window units, there is considerable choice over its design. The number of sections, frame finish, glazing and opening windows can be selected to suit the size and appearance of the house. Bow windows are particularly effective in living rooms and other spaces where homeowners want to make more of an external view. The angled arrangement allows daylight to enter from several directions and provides a wider outlook than a conventional flat window.
New bow windows can also be designed with an external roof above the projection. The roof style and finish can be selected to work with the existing property, helping the completed installation look like an integral part of the house rather than a later addition.
Replacing an older bay or bow provides an opportunity to improve thermal performance throughout a large glazed area. Modern energy efficient double glazing, insulated frame systems and effective weather seals can reduce unwanted heat loss and cold draughts. South Lakes Windows can provide A-rated windows and advise on appropriate glazing specifications for individual properties. Specialist options can include acoustic glass where external noise is a concern, laminated glass for additional security and obscure glazing where privacy is required. There are also many ways to retain the character of an existing window. Georgian bars, astragal bars, leaded designs and other decorative glazing details can be incorporated where appropriate. A wide selection of frame colours and woodgrain finishes allows replacement windows to complement existing doors, windows and exterior finishes.
Security forms an important part of the specification. Opening sections can incorporate modern locking systems, secure hardware and appropriate safety glazing, providing a considerable improvement over many older bay and bow window installations.
The quality of a bay or bow window depends on accurate surveying and correct installation as much as the windows themselves. Multiple frames must be correctly positioned, joined, supported and sealed to provide the expected appearance and performance. South Lakes Windows provides a complete bay and bow window supply and installation service. We will assess your existing windows, discuss the different materials and configurations available, take accurate measurements and prepare a specification for your property. Our experienced window installers then complete the fitting and finishing work.
