How fixed glazing works day to day

Designed as a sealed element, the round window has no operating sash and cannot provide ventilation. There is no handle to use, opening direction to allow for or sash to secure during ordinary use. Its glass stays fixed while the circle provides a calm, permanent feature. This works well where natural light is desired but regular opening is unnecessary at that particular point in the room.

For planning, consider how the fixed glazing fits into the wider ventilation and window arrangement. If the room is to be ventilated through windows, another suitable opening element must be included. Also coordinate the glazing-bar pattern with the intended view and nearby design lines. This choice divides the glass area, so assess it together with shape, size and installation position.

Day-to-day care concerns the accessible faces of the pane, frame and bars. How readily they can be cleaned or maintained is governed by the chosen installation position. For a high or difficult-to-reach opening, plan early for future access to the inner and outer surfaces. This is a practical consequence of where the unit is installed, rather than an inherent feature or limitation of the window.

The fixed construction supports a clear visual composition, bringing the circular form, glazing and glazing bars to the fore. Anyone using a circular opening as a deliberate architectural accent gains an element with straightforward daily use. The key point is that its permanently closed function suits the room’s requirements and the overall window plan. The unusual shape then becomes an intentional solution rather than a later compromise.

Construction, components and dimensions

The fixed insulating pane sits in a circular oak or pine outer frame, with black silicone seals beside the glass. The outer-frame profile is specified as 105 × 57 mm; those dimensions refer only to that component, not the complete unit. Establish the bespoke overall size separately for the prepared opening and project.

The mounting holes specified for the unit are 14 mm in diameter. Record this separately from the overall window size and the dimensions of the opening. Fixings and junctions must be chosen for the actual wall construction and site conditions. To avoid ambiguity in a bespoke request, label the window size, aperture size, outer-frame section and mounting-hole diameter individually.

Specify a double- or triple-glazed insulating unit. Each has a heat-reflective coating, argon filling and the stated CHR warm-edge spacer. Black silicone seals the glass-to-timber junction. Name the required glazing build-up clearly when enquiring about the bespoke window.

The round window is CE marked and covered by a 5-year guarantee. In the enquiry, list the required overall size, oak or pine, the selected double- or triple-glazed insulating unit, the full glazing-bar option name and colour. Assign the 105 × 57 mm outer-frame profile and 14 mm mounting holes to their respective components. This organised summary helps confirm the intended specification.

05

Assessing the proposed opening carefully

Before ordering a bespoke round window, establish the proposed aperture precisely. A rough dimension or presumed standard format is not enough for a circular opening. Note the actual overall window size required and define what every measurement represents throughout the enquiry and drawings. Clear labelling keeps the aperture dimensions, finished-unit dimensions and measurements of individual components distinct.

Check the opening across several positions to confirm that it is consistently circular and ready for the intended installation. Its surrounding construction is also relevant: linings, internal and external junctions, and adjacent finishes affect which parts remain exposed or accessible. Do not apply standard deductions or additions without assessment, since the installation detail must suit this project's actual build-up.

Allow enough space around the element for the proposed work. Because the window is fixed, this does not refer to sash travel; it means the room needed to position, fasten and connect the unit and to access it later. For a high opening or an unusual wall construction, document the arrangement with labelled sketches or photographs and have the proposed measurements checked professionally.

State which viewpoint is used when assessing the composition. A glazing-bar pattern may interact differently with the façade, the interior or nearby architectural lines. Even though a plain circle initially seems to have no direction, mark inside and outside, together with top and bottom, on every relevant drawing. Those references are essential for horizontal, vertical and combined bar layouts. Careful records of the opening therefore provide a sound basis for an exact made-to-measure enquiry.

Timber, colour and visual composition

This circular window is offered in oak or pine. The selected species shapes the frame's character and how it sits beside other joinery, interior surfaces or the façade. The decision involves more than shade: each timber's grain and material presence may either quieten the round outline or make it more prominent. Select from these two stated options according to the project's visual direction.

You may also specify a colour. Describe the intended shade precisely when submitting an enquiry, because terms such as “light”, “dark” and “natural” are open to interpretation. Judge it against surrounding finishes, neighbouring doors or windows and the selected arrangement of bars. A contrasting finish makes the circle stand out, while a closely related tone integrates it more quietly.

Glazing bars play a major role in the composition. Identify your selection with the exact design name explained earlier, removing doubt about the intended layout. Compare its geometry with adjacent architectural lines and review how it reads from indoors and outdoors. Using only the listed options, the round window can be integrated quietly or treated as a deliberate graphic accent.

Consider timber species, chosen colour, glass and glazing bars together rather than as isolated decisions. Review the combination beside adjacent finishes, other windows or doors, and established lines in the architecture. A simple treatment can emphasise the circle with restraint; a divided design creates a bolder graphic presence. The right balance depends on the particular setting and its overall design intent.

07

Comparing fixed glazing and opening functions

Start the comparison with the outline required by the scheme. This unit is intended for a circular aperture where the glass will stay permanently fixed. Triangular and sloping fixed windows are also non-opening, though their contours serve different designs. Depending on the related model, pine or oak and aluminium-clad variants may be offered. The prepared opening and drawings should therefore determine the first choice of shape.

If the room needs ventilation from this position, review outward-opening products instead. Options include pivoting windows, top-hung casements and side-hung types with one or two sashes. Specifications are model-dependent and may include oak or pine, aluminium-clad versions and a selection of handles. Along with the preferred operating action, allow sufficient clear space outside for the open sash to move safely through its full path.

One-sash and two-sash side-hung windows differ principally in configuration and everyday operation. Traditional-style models provide another design route and are available in oak or pine. When the requirement is an exterior doorway rather than glazing alone, consider the associated patio doors with one leaf. These doors swing outwards and feature ASSA 3-point locking; the available materials and detailing vary with the model selected.

Narrow the options by considering aperture shape, fixed or moving glass, operating direction, sash configuration and whether the unit must function as a window or door. Then review the timber choices, any aluminium cladding, double or triple insulating units, bar layouts, finish and applicable handle for the individual model. This approach compares each construction on its own available specification.

Preparing your enquiry in clear steps

Begin with the essential question: does this position call for a circular unit that will always remain shut? If so, record the product as “Fixed-glazed circular window” and separately note that no opening action is required. Stating the geometry and fixed operation at the start provides a clear brief and avoids confusion with an operable round window.

Then compile all measurements relevant to the scheme. State the required overall window dimensions, how they were established and the orientation shown in the drawings. Add a plain description of the proposed location. Dimensions quoted for particular product components cannot replace the overall size measured for the opening. A labelled sketch showing reference points and viewing direction will support accurate discussion.

Set out the appearance choices next. Name oak or pine, specify the colour accurately and use the full catalogue wording for the glazing-bar design. Add the required insulating-glass option. Where you have considered several possible combinations, identify the final preference clearly before sending the enquiry, keeping exploratory ideas distinct from the selection you wish to pursue.

Finish with a brief consistency check. Confirm that ventilation is provided elsewhere, the glazing-bar layout has the intended orientation, and the drawings clearly mark inside and outside. Keep questions still to be resolved separate from choices already made. The resulting enquiry will be straightforward to review and will provide a reliable basis for the next specification discussion.

Does the circular window open?

No. This model uses permanent glazing and has no sash that can be operated. It is appropriate where the circular form and incoming daylight are wanted, while ventilation for the room is provided by another suitable method.

Is bespoke sizing offered for this window?

Yes. The round window can be sized for the scheme. Provide precise details of the intended opening and installation context. Final dimensions need to account for the construction, junctions and proposed fitting arrangement.

Which timber species can I choose?

The specified timbers are oak and pine. Each gives the circular frame a different appearance. Compare them with the adjoining materials, preferred surface treatment and wider design scheme before deciding which better complements the project.

How is the insulating glazing constructed?

The insulating unit incorporates a heat-reflecting layer, an argon-filled cavity and a spacer formed with a warm edge. Include these construction details and the required glazing version when preparing the enquiry.

How long is the round window guarantee?

This round window includes a 5-year guarantee. Keep records of its dimensions and chosen timber, colour, glazing and bar pattern so the exact version ordered remains clear in the product documentation.

Can I choose a glazing-bar design?

The pane may be ordered without glazing bars or in any listed arrangement. The choices cover level and upright straight-bar patterns together with a circular-bar version. Refer to the precise option title when selecting.

Can the round window have a chosen colour?

Yes. A colour can be selected. Since its effect depends on the timber, glazing bars and neighbouring finishes, state the exact shade requested rather than relying only on general terms such as light or dark.

Is the round window CE marked?

Yes. This product carries CE marking.

Define your preferred specification

Once the form, bespoke size, timber, glass, bar design and colour have been chosen, place them together in a well-organised enquiry. Include the intended location and separate any matters still needing agreement. This gives both sides a shared description of the requested version from the outset and lets us address the decisions already recorded.
