Our outward-opening top-hung window brings light and fresh air into British homes, extensions and refurbishment projects. Made to measure, it combines an opening sash with a choice of timber, glazing and decorative details, so you can give a practical everyday window a considered place in your home.
Whether you are replacing a single unit or planning a group of new openings, start with the way you want the room to feel and function. The following guide explains this window’s construction and available options, then helps you organise the decisions that turn an initial idea into a clear configuration.
01
The opening sash lifts outwards, keeping its movement outside the room rather than bringing the open pane across a worktop or furnishing. This distinction is useful when space around the window is limited, but the external opening path also deserves attention. Consider who uses the area outside and what may be placed there in future so that the sash has suitable clearance for everyday operation.
For everyday ventilation, consider when and how you will use the window. A kitchen used throughout the day presents a different routine from an occasional study. Will you normally be standing at the window, approaching from the side or reaching across a counter? Trying the intended position in the room can make those questions clearer than looking at an elevation drawing alone. Choose a location from which normal operation feels convenient.
Because the sash projects outside, it is sensible to consider what lies directly beyond the elevation. Allow for the opening path when the window faces a path, planted area, exterior fitting or another architectural element. Indoors, the absence of an inward swing can make coordination with curtains and blinds more straightforward, although any chosen covering should still leave the handle accessible and permit the sash to operate freely.
A top-hung window offers a different opening experience from a side-hung model. If you prefer a vertical hinge and a sash that opens from the side, the provides a useful single-sash comparison. Choosing between the two is primarily about the desired movement, the proportions of the aperture and how you expect to use the opening from day to day.
02
The window is available in pine, pine with aluminium cladding, oak or oak with aluminium cladding. Pine provides a versatile timber choice with a straightforward appearance, while oak gives the frame and sash a distinct natural timber character. Your decision can be guided by the interior finish you want to create, the surrounding joinery and the visual relationship between the new window and other openings in the property.
Aluminium cladding is a choice available with either pine or oak. It changes the exterior build and the relevant frame and sash dimensions while retaining timber as the specified base material. This can be especially useful when you want the internal presence of pine or oak combined with an aluminium-clad external expression. An unclad timber configuration may be preferred when exposed timber is important to the overall architectural treatment.
The standard frame section is 105 × 57 mm, and the frame with aluminium cladding is 115 × 57 mm. The sash section is 76 × 65 mm, increasing to 86 × 65 mm with aluminium cladding. These are product section dimensions rather than the overall made-to-measure window size. They should be considered alongside the aperture dimensions, surrounding construction, internal reveal and any planned finishing details.
Material selection is also an opportunity to coordinate this window with adjacent units. For a wider opening where a pair of side-hung sashes may be more appropriate, compare the . That design changes both the number of opening sashes and the opening action, so it should be treated as an alternative layout rather than as a larger version of this top-hung product.
03
You can choose a 2-pane or 3-pane glazing unit. Both options are specified with a heat-reflective coating, a warm-edge spacer identified as CHR and argon gas. This combination forms part of the product’s glazing specification, while the choice of pane count allows you to coordinate the window with the wider glazing approach for your project.
The decision between 2- and 3-pane glazing should be made in the context of the wider project rather than appearance alone. Consider the performance approach for the complete building, the intended use of the room and the glazing selected for nearby windows and doors. Consistency across related openings can help create a coherent result, particularly on an elevation where several glazed units are viewed together.
When comparing quotations, keep the glass selection visible as a separate item. A photograph of a finished window cannot tell you the pane count or identify all the components within its glazing unit. Ask for the selected option to be written into your configuration so that a change of colour or decorative design does not distract from the glazing decision. That gives you a clearer basis for comparing otherwise similar proposals.
For projects where traditional visual language is a priority across a broader double-sash opening, the is another relevant product to compare. It combines historic styling with two outward-opening side-hung sashes, whereas this window uses one top-hung opening sash. Looking at these formats together can clarify whether the elevation calls for top-hung simplicity or a more explicitly side-hung composition.
04
The simplest design uses one opening sash without decorative bars, giving you a clean glazed area and a restrained contemporary character. If you want more definition, available layouts introduce horizontal bars, a vertical bar, or a combination of both. The chosen pattern can visually connect the window to existing joinery, establish a stronger rhythm across an elevation or add traditional detail to an otherwise straightforward opening.
Horizontal options include one, two or three horizontal decorative bars. A single vertical decorative bar is also available. Combination layouts comprise one horizontal and one vertical bar, two horizontal bars with one vertical bar, or three horizontal bars with one vertical bar. The bars create visual subdivisions within one sash; the sections are not separately operated panes.
Proportion matters when selecting a pattern. On a compact window, a large number of divisions can create a busier appearance, while a broader or taller opening may accommodate several bars more comfortably. As practical design advice, compare the proposed pattern with the shape of the aperture, nearby window divisions and important sightlines. A simple drawing of the elevation can help you judge the rhythm before settling on a layout.
If your project combines different sash arrangements in one façade, decorative bars can provide a common visual theme without forcing every opening to use the same operating format. The offers a Kombi outward-opening side-hung alternative for comparison. Its opening arrangement differs from this top-hung sash, but reviewing both may help when planning a coordinated family of windows.
05
For a replacement project, distinguish the visible size of the old window from the dimensions needed for the new order. Surrounding finishes can conceal the edges of an existing frame. Have the aperture and intended fitting arrangement established for the actual building, and use the construction dimensions above when discussing the chosen frame with your installer. Keep the measurement record attached to the relevant opening rather than relying on a room name alone.
The frame has 14 mm fixing holes. The surrounding substrate, opening preparation, tolerances, support and sealing strategy should be assessed for the actual building. A fixing-hole diameter is one product detail, not a complete fixing specification. Agree how the frame will be secured and how its junction with the wall will be finished before confirming the order. This helps separate the window configuration from the work needed around it.
Identify which existing finishes you expect to retain. Internal plaster, external trims and the sill can each influence the sequence of a replacement project. Photographs taken from both sides are useful when discussing these details, especially if someone preparing the enquiry has not visited the property. Include a wider photograph as well as a close view so that the relationship between the opening and the surrounding wall is clear.
For several windows, give each aperture a simple reference on your drawing and use it consistently in correspondence. This reduces the chance of a colour or design choice being assigned to the wrong room. If one opening needs a different style, flag it separately: the is an alternative worth reviewing where a historic-style combined side-hung arrangement is wanted.
06
A successful window choice should relate to more than a single room. From outside, consider the alignment of heads and sills, the spacing between openings and the pattern created by decorative bars. From inside, look at the colour, timber choice and visual depth of the frame in relation to floors, cabinetry, wall finishes and other joinery.
Colour options can be selected to coordinate the exterior elevation, interior palette or existing windows. Handle choices provide a further finishing decision. It is worth reviewing these elements together rather than treating each one in isolation: the material establishes the main character, colour affects how strongly the frame stands out, and the handle contributes a smaller but noticeable functional detail.
For period-influenced work, oak, divided glazing and carefully judged proportions may help support a more traditional composition. For a modern extension or restrained refurbishment, an uninterrupted sash and a simplified colour relationship may be more appropriate. These are design approaches rather than fixed rules; the best configuration is the one that responds to the building without adding unnecessary visual competition.
Where the project includes glazing in a roof, compare the separately. A roof opening and a wall opening occupy different positions in the building, so selecting one does not settle the choice of the other. On a room drawing, mark both and consider where you want daylight to fall: near a desk, across a work surface or into a circulation area. This gives each opening a clear purpose within the overall scheme.
07
SPILKA hardware is specified for this window, and handle choices are available. When selecting a handle, think about the fittings you already find comfortable to use. A finish that looks appealing in isolation may feel more or less prominent once it sits beside a painted frame. Bring a photograph of nearby handles or cabinet fittings to the comparison if you want a coordinated interior.
Black rubber glazing seals are specified. For a closer understanding of the finished appearance, review the product photographs together with your selected colour and material. Keep the difference between a photographed example and your own proposed configuration clear: a particular image may illustrate a decorative-bar option that you are not choosing. Record the decisions in words as well as referring to an image.
The selectable choices for this window include made-to-measure sizing, colour and handle, alongside the specified material, glazing and decorative-bar layouts. Treat the handle as part of the practical brief: note where the window will sit, whether a worktop or furniture affects reach, and how you expect to use the outward-opening sash. Recording these points together helps align the finished appearance with comfortable everyday operation.
The window is CE marked and comes with our five-year warranty. For a scheme that also needs an outward-opening access point, the provides a single-leaf patio-door comparison. Give the door its own place in the project schedule: pedestrian access and a window opening serve different purposes, even when you want their finishes to coordinate.

A useful enquiry makes the project easy to understand. Tell us whether you are replacing an existing window or creating a new opening, identify the room, and explain which choices you have already settled. If there is one question holding up the decision, put it first. You do not need a finished interior scheme to begin comparing options; a clear description of your priorities is a practical starting point.
Separate firm decisions from possibilities. For example, you may have chosen the timber but still be comparing two decorative-bar arrangements. Ask for those alternatives to be identified distinctly, rather than combining them into an ambiguous description. When considering a change, keep the other selections consistent so that you can understand what the change actually means for your proposed window.
Before placing an order, review the configuration as a whole with everyone involved in the project. Check that the opening reference, size, selected options and intended position all describe the same unit. If a drawing or quotation is revised, use that current version for the final discussion. Keeping a single agreed record is particularly helpful when a homeowner, installer and another project contact are sharing information.
For a traditional patio-door treatment alongside this window, the is a further option to explore. Compare its styling with the overall elevation while keeping each product’s configuration separate. Contact our team with your project outline and the choices you want to discuss; we can help you compare the available window and door options and bring your enquiry into focus.
Top-hung window questions
Make two simple sketches at the same scale and show the surrounding wall in each. Compare the patterns from the room as well as from the outside elevation. Using the same outline for both helps you judge the divisions themselves instead of being distracted by different drawing sizes.
They can share a colour or design detail without being identical. Consider which openings are seen together and where you want a consistent visual rhythm. Different functions may call for different products; choose a relationship between them that feels deliberate rather than assuming every unit needs the same arrangement.
Use a photograph to explain the look you prefer, then confirm the actual configuration separately. The glass specification and made-to-measure dimensions cannot reliably be established from the picture. A written selection avoids treating an illustrative example as a complete description of the window you want.
A wider photograph of the elevation can be especially useful. It shows the neighbouring proportions and finishes that the replacement will sit beside. Also explain which features you want to retain and which you would like to change, so the comparison has a clear starting point.
Change one main choice at a time and label the alternatives clearly. For instance, keep the same size and decorative layout while considering a material change. This makes your priorities easier to discuss and helps prevent an option from one proposal being accidentally combined with another.
List each opening separately and identify its room and drawing reference. Note any room-specific requirements beside that entry. A single project can include several configurations, and a schedule helps keep those individual decisions organised when you discuss the complete order with us.
You can contact us to discuss the available choices while you are planning. Make clear that any initial measurements are provisional, and have the dimensions needed for ordering confirmed before the final configuration is agreed. This lets the early conversation focus on selecting a suitable product.
Bring your opening references, relevant photographs and a short list of unresolved choices. Tell us what matters most to you, such as the appearance alongside existing joinery or the preferred decorative layout. We can then focus the conversation on the available options that you want to compare.
