01

Everyday operation and use

The semi-circular window uses fixed glazing and cannot be opened. In everyday use, there is therefore no change between open and closed positions. Its role in your plan is to provide a permanently closed glass area in a distinctive semi-circular form. If you also require ventilation or an opening access point on the same side of the building, provide that function through a separate, suitably chosen element. The semi-circular window remains a fixed-glazing unit independently of it. This clear division is particularly useful when a project contains elements with different purposes: the curved window provides the visual feature, while another product may provide the required movement or opening.

As the window does not open, everyday access to the glass surfaces should be considered during project planning. This is not an additional product feature, but a practical consideration for the installation location. If the element is positioned above another window or in a hard-to-reach place, you can assess in advance how accessible surfaces can be reached in your building. This may be judged differently at an easily accessible position. The important point is not to confuse fixed glazing with an operable window, and to plan its intended use accordingly.

The glazing-bar pattern affects the everyday appearance of the window without changing its fixed function. A bar-free version emphasises the uninterrupted semi-circular surface and clean outline. Horizontal lines can relate to cornices, frame lines or other level elements, while vertical lines can continue an existing axis. Combining both directions divides the surface more strongly. When choosing, consider not only the window itself but also neighbouring openings and repeated lines across the façade. This helps you decide whether the semi-circular window should sit quietly within the design or stand out as an independent feature.

Construction, component dimensions and technical details

The key technical details help with comparison and preparation of your configuration. The outer frame is specified as 105 × 57 mm; these values apply only to the outer frame and do not describe the overall width or height of the made-to-measure window. Installation holes are specified as 14 mm. The semi-circular window is CE marked and offered with a five-year manufacturer guarantee, subject to its terms. Because the window is made to measure, record the required element dimensions and details of the intended opening separately from the outer-frame dimensions. This keeps it clear which values describe the complete window and which refer only to individual components.

Choose either double or triple insulating glazing. Both options include a heat-reflective coating, a warm-edge spacer (CHR) and argon fill. Silicone is used for the glass seals. Pine and oak are available for the frame. State the required timber species, colour, glazing and glazing-bar design explicitly in your enquiry. This allows the required semi-circular window to be described clearly and distinguished from the dimensions of the intended opening and the fixed technical component details.

The semi-circular construction uses permanent fixed glazing. It remains a non-opening window even when glazing bars are selected. For the design, take particular care to use the complete variant name, as the range distinguishes between glazing bars and bars explicitly described as glass-dividing. Record the selected name as precisely as possible and indicate in drawings or sketches which details refer to window dimensions, the outer frame, glazing or the glazing-bar pattern. This separation makes coordination easier and prevents a design line being confused with a component measurement or another version.

Assessing the intended opening correctly

Because the semi-circular window is offered made to measure, reliable planning begins with a clearly described intended opening. With a semi-circular shape, a general note such as “rounded at the top” is not always sufficient. The geometry should be documented so that the straight boundary, curve and their relationship remain understandable. The appropriate method of recording this information depends on the existing situation. For a new build, plans may be most important; for an existing opening, traceable records and informative views can also help.

Check that the opening is genuinely intended for a semi-circular element and that adjoining building components make the shape clearly recognisable. Do not rely solely on a front-facing photograph if perspective or obstructions could distort the outline. A labelled sketch can explain which edges the information refers to. If several similar openings exist, each should be assigned clearly to its installation location. These steps are recommendations for preparing your enquiry; they neither change the product shape nor replace assessment of your specific project.

Also allow for the required clear space around the proposed position where relevant to your building situation. Adjacent cladding, reveals, roof lines or other elements can affect how the semi-circular form appears in the overall view and how the proposed position must be described. The window itself does not open, so there is no sash movement area to plan. Nevertheless, the fixed-glazing unit should be located clearly within the intended opening. Keep details of the building opening separate from the outer-frame component dimensions; they describe different matters and should not be treated as equivalent.

Colour, timber species and visual composition

Choose pine or oak for the frame, with a choice of colour also available. State the desired colour together with the timber species, as both choices form part of your configuration. As no particular colour is prescribed here, the selection remains open for coordination with your project. Consider not only the semi-circular window in isolation but also adjacent windows, doors, cladding and other visible surfaces. A considered match can integrate the element into an existing colour scheme or allow it to appear as a clearly distinct component.

The semi-circular form already has a strong geometric presence. Colour and the glazing-bar pattern can organise that effect further without changing the window type. A calm, bar-free surface brings the outline to the foreground. Horizontal divisions can connect with other level lines, while vertical patterns can pick up an existing axis. The combined pattern may be a useful design consideration where both directions occur in the scheme. These are possible ways to consider your selection, not guaranteed rules for how the finished element will look in every setting.

If your project includes several timber windows or doors, decide before making an enquiry how the semi-circular window should relate visually to neighbouring elements. A consistent timber species and colour choice can create a calm connection, while a deliberately contrasting design can highlight the special semi-circular form. Record the timber species, preferred colour and complete design name separately so that each choice is captured clearly. Additional views of the building can show existing colours, materials and lines. This allows the visible composition to be planned intentionally without mixing technical window components with design choices.

Related window and patio-door types

As fixed glazing, the semi-circular window has a different task from an opening window. If your project requires both a semi-circular glass area and opportunities for ventilation or opening, these functions can be assigned to separate elements. The related range includes outward-opening pivot, top-hung and casement windows. These may suit positions where an opening function is required in addition to daylight. For each installation location, first decide whether permanently fixed glazing or an operable element is needed, then select the product type suited to that purpose.

For opening window positions, compare single- or double-sash models according to the required version. Where an outward access point is planned, related single-leaf patio doors may be relevant to further planning. Some window and door models are also available in a heritage style. This allows different functions within one project to be considered separately: the semi-circular window forms the fixed, curved part, while another window or patio door provides the required opening function. Compare every element using its own product details and configuration options rather than transferring the semi-circular window’s features to other models.

When combining several elements, it is helpful to make a simple overview of the intended positions. Mark where the fixed semi-circular window is to be used and where an opening window or patio door is planned. Add the function, required dimensions and design choices for each position. This keeps different product types clearly assigned even when they appear in the same façade view. The following selection of related windows and patio doors helps you open suitable product pages for other positions in your project.

Prepare your enquiry in a few steps

Begin with the clear product name “Semi-circular fixed window”. Then note where the element is planned within your project and whether it will appear alone or in a composition with other windows or doors. This brief context helps explain your design intention without attributing additional functions to the product. If you are enquiring about several semi-circular elements, give them clear position labels so that decisions are not accidentally mixed between different installation locations.

Next, choose the timber species and note your colour preference. Add the required glazing build-up from the available selection. For the design, use exactly one of the listed names, including the term “glass-dividing” where it belongs to the selected pattern. For the bar-free design, state “No glazing bars”. Keeping these details separate prevents material, colour, glazing and bar pattern from becoming one unclear design request. If you include reference views, label what they are intended to illustrate.

Finally, check that all details are clearly assigned to a position and that timber species, colour, glazing and glazing-bar pattern are each stated separately. If any decisions remain open, identify them specifically rather than replacing them with an approximate description. Clearly labelled drawings, sketches or images can also show where the semi-circular window is planned and which surrounding lines matter to the design. Take care not to confuse opening dimensions, required element dimensions and fixed component details. A clearly structured enquiry allows us to discuss the available options with you efficiently.

Can the semi-circular window be opened?

No. This semi-circular window uses fixed glazing and cannot be opened. It is therefore suited to a plan in which the semi-circular glass area and daylight are central, while ventilation or an opening access point is provided elsewhere.

Which timber species are available?

Choose between pine and oak. Neither timber species changes the basic product type: it remains a semi-circular fixed-glazed window. Consider the other timber surfaces and the desired overall effect of your project when deciding.

Can I choose a colour for the window?

Yes. A choice of colour is among the available purchasing decisions. As the right effect depends on the building, adjoining components and your design concept, state the desired colour clearly in your enquiry.

Is made-to-measure manufacture possible?

Yes. The semi-circular window is offered made to measure. It is important that the shape and relevant details of the intended opening are recorded clearly. For a semi-circular outline, avoid ambiguous sketches or only broadly estimated values.

Which glazing-bar designs are available?

The semi-circular window can be designed without glazing bars, with one horizontal or vertical bar, or with a combination of one horizontal and one vertical bar. There is also a horizontal bar in the lower area and versions with one or two glass-dividing bars in a horizontal or vertical direction. State the complete design name, especially when requesting a glass-dividing option.

How is the insulating glazing constructed?

Double and triple insulating glazing are available. Both versions have a heat-reflective coating, a warm-edge spacer (CHR) and argon fill. Silicone is used for the glass seals. State the required glazing build-up together with timber species, colour and glazing-bar pattern in your enquiry.

Is the semi-circular window CE marked and covered by a manufacturer guarantee?

Yes. The semi-circular window is CE marked and carries a five-year manufacturer guarantee, subject to its terms. This commercial guarantee is separate from any consumer remedies that may apply to the transaction under New Zealand law.

What can I choose if I also need an opening element?

If you also need an opening function, plan a separate window or patio door for that purpose. The related range includes outward-opening pivot, top-hung and casement windows, plus single-leaf patio doors; some models are also available in a heritage style. The semi-circular window remains a fixed-glazing, non-opening unit regardless of the combination.
