Open inward and tilt comfortably

The window has one movable sash that opens inward and can also be tilted. This lets you choose the operating position that suits everyday use without having to manage several sashes. Unlike fixed glazing, this model can be opened; unlike outward-opening windows, it moves into the room. When planning, therefore consider the position of the sill, furniture and other nearby items. A drawing showing the intended furniture makes this spatial relationship clear before visible details are selected.

Because the sash opens inward, it is sensible to allow suitable movement space on the room side. During planning, check whether the sill, furniture, decorations or other objects could obstruct this area. Clear space immediately around the window is also useful for the tilted position. This is not about a universal room layout, but about the actual use at the intended installation location. Careful planning helps you use both functions as you wish every day.

With a single sash, operation is concentrated in one window element. Consider who will use it regularly and from which position the handle will be reached. A worktop or deep table in front of the window can affect access, even if the movement area is generally clear. Mentally rehearse the usual hand movement in the furnished room. This practical assessment connects your window choice with everyday habits and helps create a coherent room layout.

02

Timber types, aluminium cladding and components

Four material versions are available: pine, pine with aluminium cladding, oak and oak with aluminium cladding. You can therefore choose an all-timber version or a version combining the selected timber with aluminium cladding. Base your decision on the desired material appearance and its design relationship with other project windows or doors. Pine and oak remain clearly defined, separate choices.

The window is fitted with Roto Frank hardware and silicone glazing seals. Installation drill holes have a diameter of 14 mm, and the product carries CE marking. Consider the hardware part of the construction and the selectable handle an additional operating detail. This supports an orderly comparison with other windows. You can ask specifically about available handle options while the model’s remaining technical features stay clearly identified. A complete product decision includes both aspects.

The outer frame measures 78 × 82 mm; with aluminium cladding, the stated size is 90.6 × 82 mm. The sash frame has the same dimensions: 78 × 82 mm, or 90.6 × 82 mm with aluminium cladding. These component dimensions must be distinguished from the overall ordered window dimensions. Record the selected version alongside its relevant values. This clarifies which component sizes apply to the all-timber version and which apply to the clad version.

05

Plan made-to-measure dimensions and opening space ahead

This window is offered made to measure. Record width and height with a clear reference, and distinguish opening dimensions from desired window dimensions. In an existing opening, differences at various measuring points should remain visible. A labelled sketch explains these relationships better than a single row of figures. Also state the viewing direction. For several windows, short position names help assign drawings to the correct location. This creates a clear basis for discussing the required version.

At the planned location, remember that the single sash moves inward and can also be tilted. Check the intended surroundings of the window in its actual use context. Relevant points may include sill depth or objects permanently placed close to the window. Consider this before finally choosing colour, handle and decorative details, because the suitable opening type is the basis for a practical everyday choice.

If the room is being altered, the plan should show the finished condition. New wall linings, a changed sill or additional fittings can affect the area around the opening. Mark which components will remain and which will be added. The glass surface should remain accessible for future care. This consideration complements planning for the sash area with access to the surfaces. A well-chosen location considers the window both in operation and as a lasting part of the room.

06

Coordinate colour, handle and material appearance

Colour and handle are selectable and contribute to the overall impression in different ways. The frame colour shapes the larger surround, while the handle provides a small visible accent. Consider which element should recede and which should stand out. A contrasting frame does not automatically need an eye-catching handle. Conversely, a deliberately contrasting detail may suit a restrained colour scheme. This balance makes the window view feel ordered and connects larger surfaces with regularly noticed details.

Timber surfaces in the room can provide a reference for the material effect. If floors, doors and furniture already show different wood tones, choose one clear focus for the window. It does not need to create a separate connection with every piece. Relating it to a permanent building element can be more convincing than following changeable furniture. View the desired version from inside and check the exterior too. The window is experienced against two different backgrounds and should be selected deliberately in both contexts.

The decorative bar pattern changes the visible amount of frame line within the glazed area. With stronger division, the chosen colour appears in more places. Always compare the colour idea on your preferred pattern, not only on an undivided sample view. If railings, joints or planting already create many external lines, a more restrained design can look calmer. Against a largely uninterrupted surface, a clearer grid can instead create an intended rhythm. The key is the relationship between window and surroundings.

Two separate views help when selecting colour: the individual window opening inside the room and the row of windows on the building. Inside, wall colour and furniture can determine the suitable tone; outside, render, cladding and neighbouring frames may be more important. Compare a preferred colour with the relevant surfaces in daylight where possible. A dark reveal makes a frame appear different from a light wall in direct sun. For a single replacement window, also consider whether it should blend in quietly or deliberately mark a change in the room design. Both can be achieved through a focused choice.

07

Compare related windows and doors sensibly

If no opening function is needed, a fixed-glazed window is an alternative. It is also available in pine or oak, each with optional aluminium cladding, and with double or triple insulating glazing. For a round, non-opening design, there is fixed glazing in pine or oak. A combination window is another distinct product type, likewise offering pine, oak and their aluminium-clad versions, with two or three panes. The first selection is therefore whether you need this inward-opening, tilt-function single-sash window, non-opening glazing or a combination window.

For projects requiring an EI30 classification, two separate window models are available. The inward-opening version has a turn-and-tilt sash, is made of oak and is fitted with Roto Frank hardware and double insulating glazing. The outward-opening EI30 model is also oak, but uses Spilka hardware and double insulating glazing. There is also an outward-opening passive-house window called Super Low Uw. It is made from pine with a special insulating material and has triple insulating glazing. Classification, material, glazing and opening direction therefore remain assigned to each model; the single-sash window presented here is a separate product choice.

Where the element is intended as access to a terrace, outward-opening single-sash patio doors are the more suitable product category. Choose a regular version in pine or oak, each also available with aluminium cladding, or a historic-style version in pine or oak. Both door models offer double or triple insulating glass and may include a panel depending on the version. They differ from this window both as doors and through their outward opening. Start the comparison with the intended purpose, then select material, glazing and design within the appropriate product category.

Prepare your window enquiry clearly and completely

For a specific enquiry, we need a clear summary of your preferred version. For each window position, state the project-specific dimensions, pine or oak, and an all-timber version or the corresponding aluminium-clad option. Add the preferred double or triple insulating glazing, named decorative bar pattern, colour and handle. Where several windows are involved, give each position a clear identifier. A table or position-by-position list can help keep different dimensions and configurations separate. This lets us see immediately which features belong together and where they are intended to be installed.

If a decision is still open, tell us your two preferred options and the key difference between them. Perhaps the new window should blend quietly into an existing room, or perhaps you want to change its appearance deliberately. A brief description of this aim helps us discuss the suitable available versions with you. You do not need to document every design route in detail. We answer product-related questions and help you find your way. The five-year manufacturer guarantee for windows and doors applies to this window. Keep the final selection with your order documents.
