01

Fixed function and everyday use

This round window is designed as a closed window element. It has no opening sash, so it does not provide ventilation. In daily use, there is no handle to operate, sash to secure or opening direction to consider. The glazing remains in place while the circular form creates a calm, lasting design feature. This can be particularly suitable where daylight is wanted but regular operation is not planned.

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

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

The fixed design supports a clear visual composition, bringing the circular shape, glazing and glazing-bar design to the fore. Anyone using a circular opening as a deliberate architectural accent receives an element that remains straightforward in daily use. The important point is that its permanently closed function suits the room and wider window design. The unusual form then becomes a considered solution rather than a later compromise.

02

Construction, components and dimensions

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

The specified 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 depend on the particular wall construction and installation situation. For an unambiguous made-to-measure enquiry, clearly identify the window size, opening size, outer-frame profile and installation holes.

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

The round window is CE marked and carries a 5-year guarantee. For your enquiry, assemble the required overall size, pine or oak, the preferred double or triple insulating glazing, the full glazing-bar design name and colour. Keep the 105 × 57 mm outer-frame profile and 14 mm installation holes assigned to their respective components. This structured information makes it easier to agree the requested version.

05

Assessing the intended opening carefully

Before choosing a made-to-measure round window, record the intended opening clearly. With a circular shape, it is not enough to state an approximate size or assume an apparently suitable standard format. Note the actual overall window size required and what each measurement refers to. This helps avoid confusing opening dimensions, window dimensions and individual component sizes.

Check the opening in several places 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 surfaces can affect which areas will later remain visible or accessible. Do not derive blanket deductions or allowances from this. Suitable installation planning depends on the particular project construction.

Clear space around the element is equally important. This does not mean sash operation, as the round window remains closed. It means the room available for positioning, fixing, connection and later access within the planned construction. For unusual wall constructions or a high position, it can be useful to document the situation with clear sketches or photographs and have the dimensional specification professionally checked.

Also decide from which side the view is assessed. A glazing-bar design can relate differently to the façade, interior or neighbouring lines. Mark inside and outside, as well as top and bottom, on your documentation, even where the pure circular form initially seems 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-measure enquiry.

06

Timber, colour and visual composition

The round window is offered in pine or oak. The timber species influences the character of the frame and can be coordinated with adjoining timber elements, interior finishes or façade design. It is not only about colour. Grain and material expression can allow a circular form to sit quietly or make it more prominent. The suitable timber for your project remains a design choice within these two named options.

A colour choice is also available. State the desired shade as clearly as possible in your enquiry. General terms such as light, dark or natural can be interpreted differently. Include surrounding surfaces, other windows or doors and the selected glazing-bar design in the decision. Strong contrast highlights the circular form differently from a colour closely matched to its setting.

The glazing-bar design is central to the composition. Use the design names explained above to specify the required appearance clearly. Consider the lines and forms of neighbouring architecture, as well as views from inside and outside. The round window can then sit discreetly within the design or act deliberately as a graphic accent, without assuming additional options.

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

07

Comparing fixed glazing and opening functions

Start product comparison with the required geometry. For a circular opening and permanently fixed glazing, this round window is the suitable product type. Triangular and angled fixed windows also have no opening function, but are intended for different outlines. Depending on the version, these related fixed windows may offer pine, oak and aluminium-clad options. First establish which form 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-hung 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 required for the open sash.

Single- and double-sash casement windows differ mainly in the number of sashes needed and the resulting use. Historic-style versions form a separate design option and are offered in pine or oak. If walk-through access to the outdoors is needed instead of a window, related single-leaf patio doors may be suitable. These doors open outwards and have ASSA 3-point locking; material and design options vary by chosen model.

Make an initial selection using a few clear criteria: opening geometry, fixed or operable glazing, desired opening method, 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 designs, colour and, where relevant, the handle. This keeps each product comparable on its own equipment options without mixing different constructions.

Preparing your enquiry step by step

Start with the fundamental decision: do you need a round, permanently closed window element here? If the answer is yes, record “Fixed round window” as the product description. Also note that no opening function is required. This concise functional description provides a clear starting point and prevents confusion with an operable round window.

Then assemble the project measurements. State clearly which overall window size is needed, how it was established and which 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-measured overall dimensions. A labelled sketch showing reference points and viewing side helps with dimensional coordination.

Next make the design choices. Name pine or oak, state the desired colour clearly and use the complete design name for the glazing bars. Also record which insulating-glazing option is required. If you are considering several combinations, identify one preferred selection at the end so a preliminary thought is not mistaken for your final choice.

Finish preparation with a brief plausibility check. Confirm that the fixed function suits the ventilation plan, the glazing-bar orientation matches the intended view, and inside and outside are marked on your documents. Keep open questions separate from your prepared selection. This keeps the enquiry clear and provides a sound 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, form and design take priority, while ventilation is addressed in another way.

Can the window be made to size?

Yes. The round window is selected to size. For an enquiry, we need clear details about 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. Both timber species change the visual effect of the round frame. Decide which suits your project by considering adjacent materials, the desired finish and the overall design concept.

How is the insulating glazing constructed?

The glazing has a heat-reflective coating, a warm-edge spacer and argon fill. These components form part of the specified insulating-glazing construction and should be included with the chosen glass option in your enquiry.

How long is the guarantee for the round window?

The round window carries a 5-year guarantee. Keep details of the size, timber, colour, glazing and glazing-bar design with your product documents so the chosen version remains clearly identifiable.

Can I choose a glazing-bar design?

You can choose the round window without glazing bars or with one of the named glazing-bar designs. These include straight horizontal and vertical divisions, as well as a version with round glazing bars. The specifically named design is decisive.

Is the round window available in a chosen colour?

Yes. A colour choice is available. As the right effect depends on the timber, glazing-bar design and adjoining surfaces, name the desired 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.

Refining your chosen version together

Once the form, made-to-measure size, timber, glazing, glazing-bar design and colour are established for your project, bring these details together in a clear enquiry. Also tell us where the window is intended and which points still need discussion. This ensures we are considering the same version from the outset and can assess your selection precisely.
