Our Pivot Roof Window gives you a made-to-measure window for a roof setting, with a pivot opening action operated by a handle at the bottom. You can choose the colour and handle, allowing you to coordinate the practical details and appearance with your room and the wider building.
The window combines pine with aluminium cladding and comes in the RAS design pattern. Its 2-pane glazing unit has a heat-reflective coating and argon gas, with black rubber glazing seals. In this guide, we explain how to assess the opening action, components, glazing and design, prepare your measurements and compare this roof window with our other window and patio-door formats.
01
Type: Pivot roof window opened using a handle at the bottom.
A Pivot Roof Window opens using the handle at the bottom. That position is an important part of the everyday experience, so start by thinking about where the window will sit in relation to you rather than considering the roof opening in isolation. You should be able to approach the window, reach the handle and operate it without fixed furniture or another feature making access awkward. The pivoting sash also needs to follow its opening movement without your room arrangement getting in the way.
Consider, for example, a roof window above a usable area of a room. A clear route to the lower handle may make regular opening straightforward, whereas a deep item of furniture directly below it could put the handle beyond comfortable reach. Before choosing the position and made-to-measure size, you could mark out the likely lower edge of the window and test how the handle position feels from where you would stand. This turns an elevation drawing into a more useful day-to-day check: can you get close enough, reach naturally and allow for the moving sash?
Your intended pattern of use should guide the decision. If you expect to operate the window regularly, give handle access and unobstructed movement particular weight. If its position is mainly being chosen to work with the roof and room layout, still check that occasional access remains practical. The handle choice can then be considered as both an operating detail and part of the room’s appearance, rather than being selected on looks alone.
02
Material: Pine with aluminium cladding; Frame: 87 × 36 mm; Sash: 97 × 40 mm with aluminium cladding.
This Pivot Roof Window combines pine with aluminium cladding. When comparing it with another window, consider the complete material specification rather than pine or aluminium in isolation. The accompanying component information gives separate dimensions for the frame and sash, and the sash specification also records aluminium cladding. Keeping these details together helps you and your fitter identify the precise construction being considered.
It is useful to distinguish the frame from the sash when reading those details. The frame relates to the fixed surrounding component, while the sash is the opening part of the window. Each has its own stated section dimensions, and the sash is specifically described with aluminium cladding. Keeping those components separate avoids comparing a frame measurement from one drawing with a sash measurement from another.
Use the pine-and-aluminium-cladding construction as the basis for assessing whether this Pivot Roof Window suits your project. Consider how the material combination works with the building, your preferred colour and the surrounding finishes. When comparing products, follow the same sequence each time: confirm the opening format, review the frame and sash information separately, check the glazing specification and then compare the supported colour and handle choices.
03
Glazing: 2-pane glazing unit with heat-reflective coating and argon gas; Glazing seals: Black rubber.
This Pivot Roof Window has a 2-pane glazing unit with a heat-reflective coating and argon gas, accompanied by black rubber glazing seals. Consider the complete glazing package when assessing the window for its proposed roof position, room use and wider project requirements. Keeping each element attached to the product name also makes comparisons with other window formats clearer.
Discuss that decision with the person planning the building work. Give them the complete specification—two panes, heat-reflective coating, argon gas and black rubber glazing seals—rather than referring only to “double glazing”. They can then consider it alongside the intended room use, the window’s position in the roof and any requirements applying to the wider project. This is particularly useful when several windows or doors are being specified, because products that look coordinated do not necessarily have the same format or glazing description.
Appearance also forms part of the decision. Assess your selected window colour alongside the glazing, surrounding interior finishes and the product imagery, taking account of how natural and artificial light may affect the overall impression. Black rubber glazing seals form part of the specification, so keep that detail with the complete product description when reviewing colours, drawings or quotations.
When comparing quotations or drawings, check that the wording follows the offered specification exactly. Do not assume that a generic reference to a glazed roof window confirms the heat-reflective coating, argon gas or black seals. Identifying each element makes it easier to compare like with like and ensures that everyone discussing the project is referring to the same Pivot Roof Window configuration.
04
Design pattern: RAS pivot roof window.
This product uses the RAS pivot roof window design pattern. Review the RAS design as a complete arrangement and decide whether it suits the intended roof opening and the architectural character of your project. Use both the product name and the RAS design name when discussing the window with us or with the person fitting it, especially if your plans include several window formats.
When assessing the RAS pivot roof window, look at the complete design shown in the product imagery. Consider its proportions as a whole, its relationship with the made-to-measure width and height, and how it will sit among any nearby roof or facade features. Avoid assuming that another product with a similar overall size has the same pattern; the product name and design name should stay together when you compare drawings.
Your colour and handle choices can adjust the character of the RAS design without changing it into a different pattern. If you want a restrained result, consider coordinating those choices with surrounding finishes. If you would prefer the window to read as a deliberate feature, you could use the available colour choice to create clearer definition. In either case, make the pattern decision from the RAS imagery first, then use colour and handle details to refine the result.
05
Made-to-measure sizing allows you to specify the width and height required for your project. Before ordering, decide where the Pivot Roof Window will sit and consider the roof and room layout, access to the bottom handle and the space available for the pivoting sash. Record the chosen width and height clearly, include the units and keep them with the full product description so the figures are not confused with dimensions for another window.
For a replacement project, ask the person responsible for the building work to confirm the made-to-measure width and height you should order. Share the product name, RAS design and intended position so the dimensions remain connected to the correct window. Once confirmed, use the same order of width and height whenever you discuss the configuration with us, and check that every drawing, note and quotation refers to the same figures and units.
For a new project, coordinate the required window size with the roof design before placing the order. The person planning the building work can check how the proposed made-to-measure window relates to the intended position and surrounding construction. You can then combine the confirmed width and height with your colour and handle choices, giving us one clearly identified configuration rather than separate details that could be assigned to different products.
Keep width and height in a consistent order whenever the figures are shared. It is also helpful to attach the agreed dimensions to the full product description—Pivot Roof Window, RAS design—particularly if the project includes several window formats. The component dimensions shown in the construction information describe the frame and sash sections; they are not a substitute for the bespoke overall manufacturing dimensions. Final confirmation should therefore come from the person who will fit the window and understands the prepared opening.
06
One visual direction is to make the Pivot Roof Window feel closely connected to the surrounding building. You could choose a colour that relates to nearby roof and exterior features, then repeat or complement that tone inside the room. This approach may suit a project where you want the roof window to sit quietly within an established palette. Compare samples or product imagery in relation to both exterior and interior finishes, and remember that colours can appear different as the light changes.
A contrasting direction gives the window more visual emphasis. If the surrounding surfaces are visually restrained, consider a colour that makes the frame and opening sash more distinct. The handle can support that choice: it may form part of a coordinated overall look or appear as a more noticeable operating detail. As the handle sits at the bottom, it will be relevant both when you view the window and when you approach it for use. Balance the visual effect against how prominent you want that frequently handled area to feel.
From outside, look beyond the window as an isolated rectangle. Consider its relationship with neighbouring openings, roof elements and facade features, paying attention to alignment and relative proportions. From inside, assess the same made-to-measure format in relation to the roof plane, surrounding finishes and the standing position from which you will use the lower handle. A colour that works well externally should therefore also be checked against the interior rather than chosen from only one viewpoint.
If the project includes several products, coordination does not require every format to be identical. You could establish one shared colour direction while allowing the Pivot Roof Window, vertical windows and patio doors to retain their different opening formats. Alternatively, if this roof window serves a distinct part of the building, consider whether a more individual colour is appropriate. Decide first whether your aim is continuity or contrast; that will make the colour and handle choices easier to resolve.
07
Start the comparison with setting and opening format. The Pivot Roof Window is the roof-window option in this group and opens using a handle at the bottom. If you are choosing for a vertical opening instead, compare it with the Two-Sash Outward-Opening Vertical Pivot Window. Its name identifies three key differences to weigh up: it is a two-sash format, outward opening and intended as a vertical pivot window. Keep that alternative separate from the RAS Pivot Roof Window when reviewing plans.
For an inward-opening format, the Single-Sash Inward-Opening Window gives you one sash, while the Two-Sash Inward-Opening Window provides a two-sash alternative. Your choice between them should begin with the number of sashes and inward-opening format described in their names. Consider which format corresponds to the intended opening and room arrangement, then follow the linked product information for its own specification rather than transferring the Pivot Roof Window’s construction or glazing details to it.
Projects with a stated fire-rated requirement should be directed to the named fire-rated formats: the EI30 Fire-Rated Inward-Opening Window or the EI30 Fire-Rated Outward-Opening Pivot Window. The distinction between them is clearly expressed through inward or outward opening, and the second is also identified as a pivot window. If EI30 is part of your project requirement, compare those dedicated products with one another and discuss the requirement with the person planning the building; do not assume that the standard Pivot Roof Window has a fire rating.
For a different outward-opening window specification, compare the Outward-Opening Passive House Window with Super-Low Uw. It has a lift-up sash, pine combined with a special thermally efficient material and a 3-pane glazing unit with heat-reflective coating, a warm-edge spacer and argon gas. Those details belong to that product and should not be transferred to the Pivot Roof Window. If the opening needs to provide full-height access instead, compare the Single-Leaf Patio Doors – Outward Opening or the Heritage-Style Single-Leaf Patio Doors – Outward Opening. Both are single-leaf outward-opening patio-door formats, while their material specifications and supported designs differ. Decide first whether your project needs a roof window, a vertical window or a patio door, then review the relevant product specification, opening action, materials, glazing and made-to-measure size.

To make the final choice, identify the one project priority that should lead the decision. For example, you may be deciding between keeping the roof window visually quiet and making it a stronger interior feature. Compare the available colour and handle choices against that priority, while treating practical access to the bottom handle and suitability of the RAS design as essential checks rather than optional styling points.
Then test the complete configuration as one choice: made-to-measure size, RAS pattern, pine with aluminium cladding, specified 2-pane glazing, colour and handle. If two preferences compete, return to the main priority. Choose the option that answers it without undermining everyday access or departing from the manufacturing size confirmed by your fitter. This is more reliable than choosing each detail independently and trying to reconcile them afterwards.
Once your required size has been agreed and you know your preferred colour and handle, contact us with the full configuration. We can help you keep the product, design and choices clearly identified as you select your Pivot Roof Window.
