Round Window with Fixed Glazing

Circular design with permanently fixed glazing

Fixed round window

This fixed round window combines a pine or oak timber frame with coated insulating glass. Choose the size, colour and one of the named glazing-bar designs to suit your scheme. As the window does not open, it is well suited to planned openings where the circular form and incoming light take centre stage.

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 remains in its intended position while the circular shape creates a calm, permanent design feature. This can be particularly useful where daylight is wanted but regular operation is not planned.

For your planning, it is important to consider how the fixed glazing fits into the overall ventilation and window scheme. 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 adjoining design lines. The choice divides the glass area and should therefore be assessed together with shape, size and installation position.

Everyday care is therefore mainly focused on 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 specific 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 consequence of the chosen location.

The fixed design supports a clear visual composition, bringing the circular shape, glazing and glazing-bar pattern to the fore. Anyone deliberately using a circular opening as an architectural accent receives an element that remains straightforward in daily use. The key is that the permanently closed function suits the needs of the room and the complete window concept. This makes the unusual form a planned solution rather than a later compromise.

02

Construction, components and dimensions

The construction comprises a round outer frame in pine or oak, permanently fitted insulating glass and black silicone seals at the glass. The outer-frame profile is specified as 105 × 57 mm. These figures 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 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. How fixing and junctions are formed within a particular wall construction depends on the actual installation situation. For a clear made-to-measure enquiry, the window size, opening size, outer-frame profile and installation holes should each be identified clearly.

The round window is available with double or triple insulating glass. Both versions combine a heat-reflective coating, a CHR warm-edge spacer and argon filling. Black silicone seals are used at the transition between glass and frame. Please 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 comes with a 5-year manufacturer guarantee. For your enquiry, assemble the required overall size, pine or oak, the preferred double or triple insulating glass, 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-measure round window, the intended opening should be recorded clearly. With a circular form, it is not enough to give an approximate size or assume an apparently suitable standard format. Note the actual overall window size required and record what each measurement refers to. This helps prevent opening size, window size and individual component dimensions from being confused.

Check the opening at several points and make sure it is genuinely circular, even and prepared for the intended installation. The surrounding build-up also matters: internal and external junctions, linings and adjacent surfaces can affect which areas will later be visible or accessible. No general deductions or allowances should be derived from this. The appropriate installation planning depends on the individual project construction.

Equally important is the clear space available around the element. This does not mean sash operation here, as the round window stays closed. It means the room allowed by the proposed construction for positioning, fixing, connection and later access. For unusual wall constructions or a high-level location, it can be useful to document the situation with clear sketches or photographs and have the dimensional specification checked professionally.

Also decide from which side the appearance will be assessed. A glazing-bar pattern can relate differently to the façade, interior or adjacent lines. Mark on your documents what is inside and outside, as well as top and bottom, even if the pure circular shape initially appears directionless. For horizontal, vertical or combined bars, this orientation is essential to the intended composition. Clear documentation of the planned opening provides the basis for a precise made-to-measure enquiry.

06

Timber, colour and visual composition

The round window is available in pine or oak. The timber species influences the character of the frame and can be coordinated with adjoining timber components, interior finishes or façade design. It is not only about colour tone. Grain and material character can place a circular form quietly within its setting or make it stand out more strongly. The suitable timber for your project remains a design choice within these two named options.

A colour choice is also available. State the required shade as clearly as possible in your enquiry. Broad descriptions such as light, dark or natural may be understood differently depending on the viewer. Include surrounding surfaces, other windows or doors, and the selected glazing-bar pattern in your choice. A strong contrast highlights the circular form differently from a colour that closely follows its surroundings.

The glazing-bar pattern is a central part of the composition. Use the design names explained above to define the required arrangement unambiguously. Consider the lines and forms of the adjoining architecture, as well as the view from inside and outside. This allows the round window to sit quietly within the design or act deliberately as a graphic accent, without assuming additional options.

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

Comparing fixed glazing and opening functions

Start product comparison with the geometry required. For a circular opening and permanently closed glazing, this round window is the appropriate product type. Triangular and angled fixed windows also have no opening function, but are intended for other outlines. Depending on the version, these related fixed windows are available in pine or oak and may also offer 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 and aluminium-clad versions, as well as handle choices, may be available. Alongside the preferred opening method, check the external space needed for the open sash.

Single- and double-sash casement windows differ mainly 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 route outdoors is needed instead of a window, related single patio doors may be suitable. These doors open outwards and have ASSA 3-point locking; material and design options vary with the model selected.

Make the initial selection using a few clear criteria: opening geometry, fixed or operable glazing, required 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 glass, glazing-bar patterns, colour and, where relevant, the handle. This keeps each product comparable through its own options without mixing different constructions.

Preparing your enquiry in clear steps

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

Next, gather the project details relating to size. State clearly which overall window size is required, 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.

Then make the design selections. Specify pine or oak, state the desired colour clearly and use the full design name for the glazing-bar pattern. Also record which of the described insulating-glass options is required. If you are considering several combinations, identify one preferred specification at the end so a preliminary thought is not mistaken for your final choice.

Complete the preparation with a brief plausibility check. Check that the fixed function suits the ventilation strategy, that the glazing-bar orientation matches the intended view, and that inside and outside are labelled on your documents. Keep open questions separate from your prepared choice. 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 provided in another way.

Can the window be made to size?

Yes. The round window is made to measure. For your enquiry, provide clear details of the intended opening and proposed installation. The final dimensions should suit the construction, junctions and planned fitting.

Which timber species are available?

Pine and oak are available. Both timber species alter the visual effect of the round frame. Decide which better suits your project by considering adjacent materials, the desired finish and the overall design concept.

How is the insulating glass constructed?

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

How long is the guarantee for the round window?

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

Can I choose a glazing-bar pattern?

You can choose the round window without glazing bars or with one of the named patterns. 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 pattern and adjoining surfaces, state 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.

Let us refine your specification together

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