Our Single-Sash Outward-Opening Vertical Pivot Window gives you one opening sash in a made-to-measure format. It is a focused choice for projects where you want the window to open outside rather than move into the room, with its size prepared for your particular opening.
You can shape the specification through the material, glazing and pattern, then choose a colour and handle to complete it. Pine, oak and aluminium-clad versions give you several construction routes, while 2- or 3-pane glazing and the listed bar arrangements allow you to respond to both project requirements and the appearance of the building.
This guide takes you through those decisions in a practical order, from everyday operation and component choices to measurement, visual coordination and the alternative window or door formats worth comparing.
01
Type: Outward-opening sash.
This is a single-sash window with a vertical pivot action, and the sash opens outwards. In everyday use, that means its opening movement is directed away from the room rather than into it. Consider what occupies the space immediately outside: the sash needs a suitable area in which to open, so the external position matters just as much as the clear internal route to the handle. The format can be particularly useful where you want to avoid an opening sash projecting into your interior space, provided the outward movement works with the setting.
Inside, concentrate on whether you will be able to approach and operate the handle comfortably. Although the sash moves outwards, a deep surface, furniture or other room arrangement below the window could still affect how easily you reach it. Your handle choice is therefore both an appearance decision and an everyday-use decision. Consider who will open the window regularly and from where they will stand rather than judging the handle only when viewing it close up.
For example, if the window is planned above a kitchen worktop, look at the complete relationship between the worktop, the handle and the outside area. The outward-opening action keeps the moving sash out of the immediate room, but you will still need to reach across the worktop to use it. You could compare the planned handle position with your normal standing position, then check outside for anything that would conflict with the sash’s movement. That one room example brings the key questions together: comfortable access from within, suitable opening space beyond the frame and an operating arrangement that suits repeated use.
02
Material: Pine, pine with aluminium cladding, oak or oak with aluminium cladding; Hardware: SPILKA, IPA; Mounting holes: 14 mm; Frame: 105 × 57 mm (115 × 57 mm with aluminium cladding); Sash: 76 × 65 mm (86 × 65 mm with aluminium cladding).
Your main material decision is between pine and oak, followed by whether you want either timber with aluminium cladding. Compare these as complete frame specifications: pine, pine with aluminium cladding, oak, or oak with aluminium cladding. If the character of the timber is important to your scheme, consider pine and oak alongside the colours, neighbouring frames and internal finishes you intend to use. A physical finish or colour reference can help you assess the combination in the same context as the rest of the project.
The aluminium-clad options change the frame and sash specification as well as the material combination. The adjoining component details show the exact frame and sash dimensions for unclad and aluminium-clad versions, so keep those dimensions with the relevant construction rather than applying one set to every option. This is especially important when coordinating a made-to-measure product with an opening, nearby joinery or other windows. Start by choosing between clad and unclad construction, then use the dimensions that belong to that decision.
The product specification names SPILKA and IPA hardware and has 14 mm mounting holes. Keep the hardware, handle and fitting information distinct when reviewing the order: the named hardware forms part of the window specification, while the handle is a choice you make for operation and appearance. The mounting-hole detail is most useful to the person responsible for fitting, so make sure they review the supplied product information together with the agreed manufacturing size.
03
Glazing: 2- or 3-pane glazing unit with heat-reflective coating, warm-edge spacer (CHR) and argon gas; Glazing seals: Black rubber.
You can choose either a 2-pane or 3-pane glazing unit. In both cases, the glazing specification includes a heat-reflective coating, a warm-edge spacer (CHR) and argon gas, with black rubber glazing seals. Pane count is therefore the variable to decide, while those other listed elements remain part of the glazing specification. Keeping that distinction clear makes it easier to compare like with like when you discuss the window with the person planning your project.
Begin with the requirements already established for the building. If glazing performance is a central project priority, ask the relevant project professional to assess whether the 2- or 3-pane unit is appropriate within the wider design. The decision should account for the complete planned opening and building specification, rather than relying on pane count as a stand-alone description. You can then choose confidently without treating features common to both units as differences between them.
Appearance also deserves consideration, particularly because the black rubber glazing seals form part of either option. If you are coordinating several windows, consider whether you want the same pane count and overall glazing specification across them or whether individual openings have different project requirements. The practical priority is to confirm the required glazing first; colour, seals and bars can then be viewed as one visual composition around the glass.
04
Available design patterns: Without decorative bars; 1 horizontal decorative bar; 1 horizontal decorative bar and 1 vertical decorative bar; 2 horizontal decorative bars and 1 vertical decorative bar; 2 horizontal glass-dividing bars; 3 horizontal glass-dividing bars.
The simplest choice is Without decorative bars. It leaves the glazing without one of the listed bar patterns, giving you the least divided appearance available for this window. Consider it if your priority is a visually quiet sash or if other parts of the façade already introduce strong lines. It can also help the window sit alongside plain neighbouring openings without adding another pattern.
The 1 horizontal decorative bar design introduces a single line across the glazing. It creates a clear horizontal emphasis without adding a vertical element. You could use that line to relate the window to a nearby architectural feature, but check its position visually rather than assuming it will align with something outside the product. This pattern suits you if you want more definition than the bar-free design while keeping the composition straightforward.
The 1 horizontal decorative bar and 1 vertical decorative bar design adds both directions to the pattern. Its combined arrangement gives the sash a more structured appearance than a horizontal line alone. Judge it as one complete design, looking at how the horizontal and vertical elements balance within your made-to-measure proportions. A taller, narrower window and a wider opening may present the same named pattern differently, so review the design in relation to the size you intend to order.
The 2 horizontal decorative bars and 1 vertical decorative bar design introduces a repeated horizontal rhythm together with a single vertical line, making it a more detailed choice than the other decorative-bar arrangements listed for this window. Consider it when you want the glazing pattern to make a stronger contribution to the façade, and compare it carefully with neighbouring windows at the made-to-measure size you plan to order. The two glass-dividing-bar options offer a different visual route: 2 horizontal glass-dividing bars create repeated horizontal divisions, while 3 horizontal glass-dividing bars increase that repetition further. When choosing between them, consider how much horizontal subdivision suits the window and the wider elevation, then compare your preferred glass-dividing-bar arrangement with the decorative-bar designs and the option without bars.
05
Imagine you are replacing an existing window after the surrounding finishes have been completed. The useful starting dimensions are the width and height between the relevant finished surfaces, not simply a nominal description of the old window. Those finished boundaries show the space the new made-to-measure product must relate to. If different points do not give an identical result, record what you find rather than selecting a preferred figure yourself.
Next, give those opening measurements to the person who will fit the window. They should use the site information and the fitting plan to agree the actual manufacturing width and height with you. Do not treat the measured opening size and the manufacturing size as automatically interchangeable: the order needs the final product dimensions that have been agreed for that particular opening. This approach keeps responsibility for the fitting decision with the person who can assess the finished opening in context.
The same principle applies in a new wall, even though there may be no old frame to remove. Establish which surfaces will form the finished opening, then make sure the dimensions used for the order relate to those surfaces and the intended fitting arrangement. Because the frame and sash dimensions differ between unclad and aluminium-clad constructions, settle the material specification before final coordination. Confirm the product as a Single-Sash Outward-Opening Vertical Pivot Window as well as stating the agreed width and height, so its format and dimensions remain connected throughout the decision.
06
For a calm, minimal direction, you could begin with the Without decorative bars design and choose a colour that sits comfortably with neighbouring window frames. This reduces the number of visual lines across the glazing and lets the single-sash format read simply. From inside, consider the frame colour alongside the wall finish and the black rubber glazing seals. The handle can either sit quietly within that composition or become a more noticeable detail, depending on the option you select.
For a more articulated direction, consider one of the combined decorative-bar designs or one of the horizontal glass-dividing-bar designs. Compare your preferred design with neighbouring frames at the intended made-to-measure proportions. In each case, the pattern should be chosen deliberately as part of the façade rather than added after the colour decision.
Look beyond the window itself when selecting colour. On the outside, compare it with adjacent windows, doors and the surfaces immediately around the opening. From the room, check how the same choice relates to nearby finishes and any other visible frames. If several openings are seen together, you could coordinate their colours while allowing the pattern to respond to each opening, or repeat both colour and design for a more consistent composition. Finally, view the handle against the chosen colour from a normal position in the room; it is a functional part you will see and use regularly, not an isolated sample detail.
07
First compare the opening formats. Our Single-Sash Inward-Opening Window is the direct alternative when you want one sash but prefer an inward-opening arrangement. The Two-Sash Inward-Opening Window changes both the opening direction and the number of sashes, so it is worth considering where a two-sash format suits the opening better. If your deciding issue is whether the sash should move into the room or outside it, settle that before comparing patterns and colour.
Where the project calls for a named performance format, compare the relevant product directly. Our EI30 Fire-Rated Inward-Opening Window combines an inward-opening format with an EI30 fire rating, while the EI30 Fire-Rated Outward-Opening Pivot Window is the outward-opening pivot option named for that rating. The Outward-Opening Passive House Window with Super-Low Uw is the alternative to review where that named Passive House and super-low-Uw format is your priority. The Kombi Combination Window should be compared if you are considering a combination-window format rather than this single-sash vertical pivot product.
A window may not be the only suitable product type for the position. Our Single-Leaf Patio Doors – Outward Opening provide an outward-opening, single-leaf door format, while the Heritage-Style Single-Leaf Patio Doors – Outward Opening offer a heritage-style alternative in the same opening direction. Compare these door formats when the opening is intended to provide passage rather than function solely as a window. Start with the fundamental project choices: window or patio door, single- or two-sash where offered, and inward or outward opening. You can then compare any named EI30 fire-rated, Passive House, super-low-Uw, combination or heritage-style requirement before considering materials, glazing and appearance choices.

Make the final choice by identifying the one priority that would be hardest to compromise. It might be keeping the sash movement outside the room, following a required glazing decision, selecting pine or oak, choosing aluminium cladding, or achieving a particular pattern on the façade. Compare your two preferred configurations against that main priority first. If both satisfy it, use everyday handle access and visual coordination as the deciding factors rather than reopening every option.
For example, if you are choosing between an unclad oak window with a simple pattern and an aluminium-clad oak window with a more articulated pattern, separate the decisions. Establish whether clad or unclad construction matters most to your project, then compare only the patterns available within the preferred route. Finish with colour and handle, checking the complete selection from both room and façade viewpoints.

QUESTIONS & ANSWERS
Yes. We make each Single-Sash Outward-Opening Vertical Pivot Window to measure. Before ordering, agree the required manufacturing width and height with the person fitting it, based on measurements taken between the relevant finished surfaces.
You can choose pine, pine with aluminium cladding, oak or oak with aluminium cladding. Compare the timber and clad options in the context of your wider window specification and the appearance you want to coordinate.
You can choose a 2- or 3-pane glazing unit. Both specifications include a heat-reflective coating, warm-edge spacer (CHR), argon gas and black rubber glazing seals. Your project planner can help you decide which pane count suits the building requirements.
The listed patterns are: without decorative bars; 1 horizontal decorative bar; 1 horizontal decorative bar and 1 vertical decorative bar; 2 horizontal decorative bars and 1 vertical decorative bar; 2 horizontal glass-dividing bars; or 3 horizontal glass-dividing bars.
Yes. You can choose a colour and a handle. Consider them together, as the handle forms part of the view from inside while the colour influences how the frame coordinates with both the room and the façade.
The sash opens outwards, so consider the clear space directly outside the window and make sure the handle position will be convenient to reach from inside. This is especially important where furniture or a worktop sits below the opening.
Compare our EI30 Fire-Rated Outward-Opening Pivot Window if your project requires an outward-opening pivot format with an EI30 fire rating. The fire-rated choice should be established from your project requirements rather than assumed from a general window format.
Our windows and doors come with a five-year warranty. This Single-Sash Outward-Opening Vertical Pivot Window is also CE marked.
