01

Fixed function and everyday use

The round window is designed as a closed window element. It has no opening sash and therefore provides no ventilation function. In daily use, there is no handle to operate, sash to secure or opening direction to consider. The glazing stays in its intended position, while the circular form acts as a calm, permanent design feature. This can be especially useful where daylight is wanted but regular operation is not planned.

For planning, consider how the fixed glazing fits into the overall ventilation and window design. If the room is to be ventilated through windows, another suitable element should be included for that purpose. Also coordinate the glazing-bar pattern with the intended view and nearby design lines. This choice affects the division of the glass area and should be assessed together with shape, size and installation position.

Daily care therefore mainly concerns accessible surfaces. Glass, frame and visible glazing bars can be maintained according to how easily they can be reached. How convenient this is depends on the actual installation position. For a high or difficult-to-reach location, consider during planning how the inside and outside will later be accessed. This is not a feature of the window itself, but a practical result of the chosen location.

The fixed design supports a clear visual composition and brings the circular form, glazing and glazing-bar pattern to the fore. Anyone intentionally using a circular opening as an architectural accent receives an element that remains straightforward in everyday use. The key point is that the permanently closed function suits the room’s requirements and the complete window concept. This makes the unusual shape a considered solution rather than a later compromise.

02

Construction, components and dimensions

The construction consists of a round pine or oak outer frame, permanently fitted insulating glazing and black silicone seals at the glass. The outer-frame profile is stated as 105 × 57 mm. These values describe this component’s dimensions; they are not the overall size of the round window. The window itself can be selected to size, so the required overall format is specified separately for each project.

The intended installation holes have a diameter of 14 mm. Record this product detail separately from the overall window size and the dimensions of the intended opening. Fixings and junctions within the wall construction depend on the individual installation situation. For a clear made-to-size enquiry, identify the window size, opening size, outer-frame profile and installation holes separately.

The round window is available with double or triple insulating glazing. Both versions combine a heat-reflective coating with a CHR warm-edge spacer and argon filling. Black silicone seals are used between the glass and frame. State clearly in your enquiry which of the two glazing options you require for the made-to-size window.

The round window is CE marked and comes with a 5-year warranty. For your enquiry, compile the required overall size, pine or oak, the preferred double or triple insulating glazing, the full glazing-bar pattern and colour. Keep the 105 × 57 mm outer-frame dimensions and the 14 mm installation holes clearly assigned to their respective components. This structured summary makes it easier to agree the required specification.

05

Assessing the intended opening carefully

Before selecting a made-to-size round window, record the intended opening clearly. With a circular form, it is not enough to give an approximate size or assume a seemingly suitable standard format. Note the actual overall window size required and what each measurement refers to. This helps prevent confusion between the opening size, window size and individual component dimensions.

Check the opening at several points and ensure it is genuinely circular, even and prepared for the planned installation. The surrounding construction also matters: internal and external junctions, linings and adjacent finishes can affect which areas will later be visible or accessible. Do not derive general deductions or allowances from this. The appropriate installation design depends on the individual project construction.

Available clearance around the element is equally important. This does not refer to operating a sash, as the round window remains closed. It means the space allowed by the intended construction for positioning, fixing, sealing and later access. With unusual wall constructions or a high position, it can be helpful to document the situation with clear sketches or photographs and have the sizing checked professionally.

Also decide from which side the view is assessed. A glazing-bar pattern can relate differently to the façade, interior or adjacent lines. Mark on your documents what is inside and outside, top and bottom, even if the circular form itself initially appears directionless. This orientation is essential for horizontal, vertical or combined glazing bars. Clear documentation of the intended opening provides the basis for a precise made-to-size enquiry.

06

Timber, colour and visual composition

The round window is available in pine or oak. The timber species affects the character of the frame and can be coordinated with adjacent timber components, interior finishes or façade design. It is not only about colour. Grain and material presence can allow a circular form to sit quietly within a scheme or make it stand out more strongly. The suitable timber remains a design choice between these two named options.

A colour selection is also available. State the required shade as clearly as possible in your enquiry. General terms such as light, dark or natural can be understood differently depending on the viewer. Include surrounding surfaces, other windows or doors and the selected glazing-bar pattern in your choice. Strong contrast highlights the circular form differently from a colour closely related to its surroundings.

The glazing-bar pattern is a central part of the composition. Use the design names explained above to specify the required look precisely. Consider the lines and forms of adjacent architecture as well as views from inside and outside. This allows the round window either to integrate quietly or become a deliberate graphic accent, without assuming additional options.

For the overall view, consider timber species, chosen colour, glass area and glazing-bar pattern together. Check how this selection relates to adjacent materials, other windows or doors and existing design lines. A restrained combination can highlight the circular form calmly, while a divided design creates a stronger graphic accent. The best effect depends on the individual design concept and intended setting.

Comparing fixed glazing and opening functions

Start a product comparison with the geometry required. For a circular opening and permanently closed glazing, this round window is the appropriate product type. Fixed triangular and angled windows also have no opening function, but suit different outlines. Depending on the version, these related fixed windows are available in pine or oak and may also have aluminium cladding. First establish which shape the design and prepared opening actually require.

If the window element needs to open for ventilation, compare the available outward-opening window types instead. These include pivot windows, top-hung casement windows and side-hinged windows with one or two sashes. Depending on the model, pine, oak, aluminium-clad versions and handle options may be available. Alongside the preferred opening method, check the external space needed for the open sash.

Single- and double-sash casement windows differ chiefly in the number of sashes required and the resulting use. Historic-style versions form a separate design option and are available in pine or oak. If a walk-through connection outdoors is needed instead of a window, consider the related single patio doors. These doors open outwards and feature ASSA 3-point locking; different material and design options are available according to the selected model.

Make a preliminary selection using a few clear criteria: opening geometry, fixed or operable glazing, preferred opening type, number of sashes, and window or door function. Then compare the timber species available for each model, possible aluminium cladding, double or triple insulating glazing, glazing-bar patterns, colour and, where applicable, the handle. This keeps each product comparable with its own equipment options without mixing different constructions.

Prepare your enquiry in clear steps

Start with the basic decision: do you need a round, permanently closed window element at this location? If yes, record “Fixed round window” as the product description. Also note that no opening function is required. This short functional description creates a clear starting point and prevents the element from being confused with an operable round window.

Then compile the project details relating to size. State clearly which overall window size is needed, how it was determined and what orientation your documents show. Add an understandable description of the intended installation location. Component dimensions from the product description should not be adopted as self-determined overall sizes. A labelled sketch showing reference points and the viewing side helps with size coordination.

Next make the design selections. State pine or oak, specify the required colour clearly and use the full design name for the glazing-bar pattern. Also note which of the described insulating-glazing options is required. If you are considering different combinations, identify one preferred specification at the end so a preliminary thought is not confused with your actual choice.

Finish preparation with a brief plausibility check. Confirm that the fixed function suits the ventilation concept, that the glazing-bar orientation matches the planned view, and that inside and outside are marked on your documents. Keep open questions separate from your prepared selection. This makes the enquiry easy to follow and gives a clear basis for further discussion.

Can the round window be opened?

No. This model has fixed glazing and no opening sash. It is intended for projects where light, shape and design take priority, while ventilation is addressed by other means.

Can the window be made to size?

Yes. The round window is selected to size. For an enquiry, we need clear details of the intended opening and desired installation situation. Final dimensions should suit the construction, junctions and planned installation.

Which timber species are available?

Pine and oak are available. Each timber species changes the visual effect of the round frame. Choose the one that suits your project by considering adjacent materials, the desired finish and the complete design concept.

How is the insulating glazing constructed?

The glazing has a heat-reflective coating, a warm-edge spacer and argon filling. These components form part of the specified insulating-glazing construction and should be stated with the required glazing version in your enquiry.

How long is the warranty for the round window?

The round window has a 5-year warranty. Keep the details of size, timber species, colour, glazing and glazing-bar pattern with your product documents so the selected specification remains clearly traceable.

Can I choose a glazing-bar pattern?

Choose the round window without glazing bars or with one of the named glazing-bar patterns. These include straight horizontal and vertical divisions as well as a version with round glazing bars. The specifically named design is what matters.

Is the round window available in a chosen colour?

Yes. A colour selection is available. As the right effect depends on the timber, glazing-bar pattern and surrounding surfaces, name the required shade clearly in your enquiry rather than relying only on general colour descriptions.

Is the round window CE marked?

Yes. The round window is CE marked.

Specify your version together

Once the form, made-to-size specification, timber species, glazing, glazing-bar pattern and colour are clear for your project, bring these details together in one straightforward enquiry. Also tell us where the window is intended and which points still need to be agreed. That way, we discuss the same specification from the outset and can consider your selection precisely.
