Shaped windows
Arched Windows and Shaped Windows Made to Measure
An arched or shaped opening needs a window measured for its actual outline, not a rectangular frame adapted by guesswork. We supply and fit shaped windows in uPVC and aluminium, considering the shape, glazing and opening sections together.
Match the outline you have
An arched window can have a shallow curved head or a more pronounced round top. Gable glazing follows a roof shape, while round or other shaped openings have their own proportions. The outline affects manufacture, glazing and the support around the window, so measurements need to capture more than width and height.
If you are replacing an existing shaped window, keep its relationship with the surrounding wall in mind. The visible frame can change the apparent curve even when the outer opening remains untouched. The survey considers the outline and frame arrangement together so the replacement is designed for that position.
Opening sections within a shaped frame
Not every shaped section needs to open. A curved or triangular upper portion can be fixed while a suitable section below provides ventilation. That can preserve a clean outline and keep the opening action practical, rather than forcing the entire shape to move.
Discuss how you reach handles and how the room is ventilated. A high gable pane can admit light but may be out of reach for daily operation. Any escape or safety requirement must also be considered for the actual opening section, not inferred from the total area of the shaped glass.
uPVC or aluminium for the outline
uPVC can suit a shaped window alongside existing uPVC frames, while aluminium offers a slimmer frame appearance that can work with contemporary gable glazing. The shape, overall size and desired opening sections influence which arrangement is suitable.
Compare the visible frame widths with neighbouring windows, particularly where a new shaped unit sits above a door or other glazing. A matching colour alone does not establish a consistent appearance. The material and profile should be considered against the complete elevation and the parts of the building that will stay.
Arched windows in period homes
A curve can be an important original feature of a period house. Changes to glazing bars, frame proportions or the position of the curve can alter its character, so a replacement should be assessed beyond the basic outline. Look at any original detailing and neighbouring windows before agreeing a new pattern.
Listed status and conservation restrictions can affect the material or design permitted. Check with the local planning authority before ordering. A timber-look foil or a similar arch does not automatically satisfy the requirements, and retaining or restoring original timber may be relevant where that is the appropriate route.
Glass, support and the surrounding opening
Shaped glass needs the right specification and support within the frame. Low-level panes, glass near a door and larger glazed areas can bring safety considerations, while the building's structure must support the opening itself. A shaped frame is not a substitute for the required support around it.
A gable window in a new or altered wall should be considered alongside the roof and structural design. If the opening already exists, its condition and weathering still need assessment. The junction with the wall and the glazing support are practical parts of the installation, not finishing details to decide after manufacture.
Make the survey and quote specific
The curve or angles, frame material, glazing pattern, opening arrangement and access all influence the work. Photographs help describe what you have, but the window is measured for the actual opening. Every frame is measured, made and fitted by our own team.
We offer a free survey with a fixed written price and no-pressure quotations, and the site is left tidy at the end of each day. Use the form below to ask about an arched, gable or other shaped window, including whether you are replacing an existing unit or planning a new opening.
Questions
Common Questions
Can arched windows open?
Suitable designs can include opening sections, often below a fixed curved head. The shape, size and hardware determine the options. Agree where ventilation and any escape opening are needed before choosing the frame arrangement.
Can you replace an arched window in a period home?
The shape and detailing can be assessed for replacement, but listed or conservation restrictions may affect the material and design. Check permissions before ordering and compare the original proportions and glazing pattern.
Are gable windows always fixed?
Not necessarily. An arrangement may combine fixed shaped panes with suitable opening sections. The structural design, reach to handles and ventilation requirements need consideration for the individual opening.
