Everyday use: inward-opening sashes and tilt function

The product type defines its operation clearly: two window sashes open inwards, and a tilt function is included. This gives you two ways to use the window; an outward-opening alternative is not part of this product. Fully opening the window requires space on the room side, while in the tilt position the sash remains in its intended angled position. Choose the position that suits the situation at hand.

For planning, the clearance inside the room is particularly important. Check whether window sills, fittings, furniture, curtains, lights or other features could extend into the intended opening area. Consider not only fully opened sashes but also convenient daily operation. Where worktops or furniture sit in front of the window, the handle should remain accessible and the intended sash position usable. This coordination is especially helpful for a made-to-measure window, because window size and the actual room can be considered together. Frequently used routes and work areas immediately in front of the window can therefore be included in the plan early on.

The two-sash layout is also a deliberate design choice. Two sashes divide the window surface differently from a single sash or a fully fixed-glazed solution. Consider operation and appearance together when choosing: if you need two opening sashes, this product type may suit the project. If opening is unnecessary or another opening direction is required, compare the window types designed for those purposes instead.

02

Timber options, aluminium cladding and frame construction

This window is available in four material versions: pine, pine with aluminium cladding, oak and oak with aluminium cladding. First choose between pine and oak, then decide whether to combine the selected timber with aluminium cladding. This choice affects both the visible material character and the dimensions of the relevant frame component. Consider material together with colour, glazing and design pattern rather than in isolation.

The stated outer-frame dimension is 82 × 78 mm; with aluminium cladding, it is 82 × 88 mm. The sash frame is likewise 82 × 78 mm, or 82 × 88 mm with aluminium cladding. Record whether you require the all-timber version or an aluminium-clad option so that the correct frame dimension is considered in planning. Outer frame and sash frame are separate components, even though their stated dimensions match for this window. The individual order dimensions must also be distinguished clearly from these frame dimensions. This keeps the material version, component and corresponding measurement clear in your enquiry.

Further features include Roto Frank hardware and installation holes with a diameter of 14 mm. The window carries CE marking. These details form part of the specified product construction, while size, material, colour, handle and glazing option can be matched to your project from the available choices. Our windows and doors come with a five-year manufacturer guarantee. This provides a clearly described basis for your configuration without mixing details from different window types.

Made-to-measure production and forward planning

As this window is available made to measure, clear project dimensions form the basis of your selection. Assign width and height unambiguously and identify each item separately where several windows are planned. Consider the intended installation position, adjacent building elements and the space available for the inward-opening sashes. The stated outer-frame and sash-frame dimensions do not replace your individual order dimensions; the two types of information serve different purposes. Alongside the required window dimensions, note the desired material version and any aluminium cladding. A clear schedule makes it easier to bring together dimensions, frame construction and design pattern for every planned window.

Allow for inward opening at an early stage. The necessary clear area depends on the chosen window size and the surroundings. A window sill, basin, worktop or other internal fitting may affect operation where it is close by. Also check curtains, blinds, plants and movable furnishings around the window. Include both full opening and the tilt position in your considerations. This helps you coordinate intended use with the room layout and identify suitable dimensions and arrangements before making an enquiry.

For patterns with fixed glazing, it is useful to name the desired layout together with the overall dimensions. Use the specific pattern description rather than simply saying “multi-part” or “with glazing bars”. This makes clear whether you mean two plain sashes, a combination with one fixed glazed section, the expressly central version or two fixed glazed sections. Clear identification reduces follow-up questions and simplifies coordination of the made-to-measure design.

Coordinating colour, handle and design

Colour and handle are among the available options. Both details shape the appearance of the window and should be chosen in relation to pine or oak and any aluminium cladding. Consider the internal and external view of the planned window in its design setting. Existing windows, doors, hardware, wall finishes and recurring colours can provide useful reference points. The selected glazing-bar pattern also affects how prominent colour and frame appear in the overall view. Record your preferred colour and handle together with material, glazing and pattern. If several windows are planned, also identify which choices apply to each item.

The glazing-bar pattern also affects the overall impression. Two sashes without bars create a different surface division from versions with one or two horizontal bars. Combinations with fixed glazing may add vertical bars, depending on the named pattern. Include not only colour but also the number and direction of the bars described in the pattern when planning the visual effect. Do not infer precise geometry or proportions from the pattern name.

For a coherent selection, a clear sequence can help: first establish the functional arrangement required, then choose the suitable design pattern, followed by material, aluminium cladding, colour and handle. Finally, assign the glazing option. This order is not a technical requirement, but it helps structure independent decisions clearly and avoids contradictions in an enquiry. The result is a configuration that considers both operation and the appearance you want.

Suitable alternatives from our window and door range

This inward-opening two-sash window is a suitable starting point when two sashes and a tilt function are required. If no opening function is needed, compare it with a fixed-glazed window instead. For distinctive window shapes, a fixed-glazed round window and a fixed-glazed semicircular window are also available; neither can be opened. A combination window may suit a project requiring another arrangement of window elements. Each product type has its own specified features.

Where opening direction is decisive, distinguish carefully between inward- and outward-opening products. The outward-opening EI30 fire-rated pivot window has the stated EI30 classification and is described as outward opening. The outward-opening Super Low Uw passive-house window is an outward-opening pivot sash. These alternatives differ fundamentally from the two-sash operation presented here, so their material, glazing and frame data must not be transferred to this window.

For a glazed access point rather than a window, compare the single-sash outward-opening patio door or the historic-style single-sash outward-opening patio door. Here too, outward opening is a key difference. First decide whether you need a window or a patio door, then compare opening direction, number of sashes, material options and design patterns within the relevant product information. This keeps the selection factual and suited to the intended application.

Outward-opening EI30 fire-rated pivot window, Outward-opening Super Low Uw passive-house window, Combination window, Fixed-glazed window, Fixed-glazed round window, Fixed-glazed semicircular window, Single-sash outward-opening patio door, Historic-style single-sash outward-opening patio door.

Request your preferred configuration clearly

For a focused enquiry, tell us the required dimensions, your preferred material version and whether you want two or three panes. Add the colour, handle and exact name of the design pattern. If your choice includes fixed glazing, state the complete pattern, especially where you mean the central fixed glazed section or two fixed glazed sections. For several windows, identify every element clearly with its dimensions and requested features. Also state whether you prefer pine or oak and whether aluminium cladding is required. This allows every configuration to be distinguished clearly from the other available arrangements.

Please also tell us which points remain open. We can help you choose from the available options and bring made-to-measure production, timber species, aluminium cladding, insulating glass, colour, handle and pattern together sensibly. A well-prepared enquiry need not settle every decision in advance; above all, it should show how the window will be used and which design direction you prefer. From there, we can discuss the next product steps with you.

Is the two-sash window available made to measure?

Yes. The window is made to measure. To ensure the order suits your building project, state the required dimensions clearly together with the desired version. When planning, also remember that both sashes open inwards.

Which materials are available?

Choose pine, pine with aluminium cladding, oak or oak with aluminium cladding. This gives you two timber species and the corresponding aluminium-clad versions.

Which glazing can I choose?

The window is available with 2- or 3-pane insulating glass. Both options include a heat-reflective coating, a CHR warm-edge spacer and argon gas. The glazing seals are silicone.

How does the window open?

It is a two-sash window that opens inwards and includes a tilt function. Allow sufficient free space on the room side for its intended use.

Are versions with glazing bars available?

Yes. There are patterns without glazing bars as well as versions with horizontal bars and, in certain fixed-glazing combinations, vertical bars. The available patterns differ according to the arrangement of sashes and fixed glazed sections.

Can the window include fixed glazing?

Yes. Alongside pure two-sash patterns, several arrangements combine two sashes with one or two fixed glazed sections. One version has a central fixed glazed section. State the complete preferred design pattern in your enquiry so the sashes, fixed glazing and bars can be identified clearly.

Can I choose the colour and handle?

Yes. Colour and handle are available choices. Coordinate both with the selected timber, any aluminium cladding and the preferred design pattern.

Which guarantee applies to the window?

Our windows and doors come with a five-year manufacturer guarantee. Keep the documents relevant to your order and selected version in a safe place.
