A casement window consists of one or more opening sections attached to the frame by hinges. Depending on the design, the opening section can be hinged at the side or along the top. Fixed panes can also be incorporated into the same frame. This straightforward design provides considerable flexibility. A small window may use a single opening casement, while a larger window can combine several opening and fixed sections. Top-opening sections can be incorporated where additional ventilation is required without opening the main window. The familiar design means casement windows work with many types of British property. They can suit traditional stone cottages, Victorian and Edwardian houses, post-war properties, contemporary homes and new extensions.
Replacement casement windows can also be designed to retain the proportions of the existing windows, which can be particularly important when maintaining the character of an older property.
South Lakes Windows offers casement windows in different frame materials, allowing homeowners to select an option that suits their property, budget and preferred appearance. UPVC casement windows provide good thermal performance with minimal maintenance. They are available in white as well as a broad selection of colours and woodgrain finishes. UPVC is particularly popular for replacement windows because it can provide an effective balance between cost, insulation, security and maintenance requirements.
For period properties and homes where natural materials are preferred, timber casement windows provide a more traditional appearance. Modern timber windows combine familiar joinery details with modern glazing, weather seals and locking systems. They can be particularly suitable for properties in conservation areas and locations where the appearance of the original windows needs to be retained. Aluminium casement windows provide slimmer frames and clean lines. The strength of aluminium allows larger glazed areas to be incorporated without requiring heavy frame sections. This makes aluminium a popular option for contemporary houses, extensions and properties where homeowners want to increase natural light. Our team can explain the differences between each system and recommend suitable options based on the requirements of your property.
Windows account for an important part of a home’s overall thermal performance. Older casement windows may have single glazing, poorly fitting opening sections or worn seals that allow heat to escape and cold air to enter. Modern replacement casement windows use insulated frames, effective weather seals and energy efficient glazing to reduce heat transfer. South Lakes Windows can supply A-rated windows and advise on the appropriate glazing specification for your home.
Double glazing provides a suitable solution for most replacement projects, while other glass specifications are available where there are specific requirements. Acoustic glass can help reduce external noise, laminated glass provides additional security and safety, and obscure glazing can provide privacy in bathrooms and other areas.
The complete window specification matters. Glass, frames, seals, spacers and installation quality all contribute to thermal performance, which is why we consider the complete window rather than glazing in isolation.
One of the main advantages of casement windows is the number of design combinations available. Homeowners can choose the number and position of opening sections according to the dimensions of the window and ventilation requirements of each room. Different arrangements can also be used to retain the proportions of existing windows when completing a replacement project.
Frame colours can be selected to complement the exterior of the property. Depending on the chosen window system, options range from traditional white and timber effects through to heritage colours and contemporary greys. Decorative details can also make a significant difference to the finished window. Georgian bars, astragal bars and leaded glass can recreate traditional glazing patterns, while larger uninterrupted panes can provide a simpler appearance for modern properties. Hardware, handles and opening configurations can then be selected to complete the specification.
For homes within a conservation area, careful consideration may need to be given to frame proportions, materials, glazing bars and other details. South Lakes Windows can discuss appropriate window ranges and help homeowners understand the options available for sensitive properties.
Accurate measurement and correct fitting are essential when replacing casement windows. Even a high-quality window will struggle to perform correctly if the frame is poorly positioned or gaps around the opening are inadequately sealed.
South Lakes Windows provides a complete service, beginning with a survey of your property. We measure each opening, discuss your requirements and help you select the appropriate frame material, window configuration, glazing and finish. Our experienced installers then remove the existing windows where required and fit the replacements carefully. Particular attention is given to alignment, weather sealing and finishing around the opening.
