01

Operation and everyday use

The sash is designed as an inward-opening tilt-and-turn sash. It offers two distinct operating modes: the turn position opens the sash, while the tilt position provides limited opening. Which position you use day to day depends on the situation. The tilt-and-turn function combines both movements in one operating system, avoiding the need for separate window elements for these types of use.

Move the handle deliberately into the required position and guide the sash in a controlled way. Where possible, change the handle position only once the relevant opening movement is complete. As the handle is one of the selectable details, you can choose a version that feels comfortable to use and complements the oak frame and selected colour.

Because the sash opens inwards, the operating movement takes place on the room side. This matters particularly for personal use: consider how you will reach the window and what routines develop around the handle. The specific spatial assessment is covered separately in the section on the intended opening. In everyday use, guide the sash carefully and ensure no objects are in its immediate path.

For routine care, visible surfaces and the handle can be kept clean using methods suitable for the relevant material. Do not use harsh or abrasive products simply as a matter of habit. Glazing, timber surfaces, silicone seals and hardware are different components and may not require the same treatment. Careful operation and component-appropriate maintenance help you treat the window as one assembly without confusing its individual materials.

02

Construction, components and dimensions

The construction is oak. The outer frame is specified as 82 × 90 mm, and the sash frame also has a component dimension of 82 × 90 mm. These values expressly describe the named frame components. They are neither the width and height of the complete window nor the finished order size for the wall opening. Overall dimensions are established for the specific project as part of the made-to-measure service.

A dimension of 14 mm is specified for the installation holes. The hardware is supplied by Roto Frank. This brand detail identifies the specified hardware; it is not a choice between different hardware brands. Likewise, oak is the fixed material for this product version, rather than a list of alternative materials. This clear allocation helps separate component details from the purchasing choices that are actually available.

The fixed product specification includes double-glazed insulated glass with a heat-reflective coating and silicone glazing seals. The EI30 fire-rated window is CE marked and offered with a five-year warranty. Together with the oak construction, Roto Frank hardware, and the stated frame and installation-hole dimensions, these features form the basis for coordinating your specific project.

When making an enquiry, it is helpful not to convert component dimensions into an assumed overall size. Instead, provide the measurements established for your project separately and clearly state what each one refers to. This keeps it clear which values describe the existing building situation and which are fixed window components. It supports precise communication, especially where sketches or several openings form part of the project.

Keep fixed product specifications separate from personal selections. Colour, handle and made-to-measure dimensions can be coordinated with your project. Oak as the frame material, Roto Frank hardware, silicone seals and coated double-glazed insulated glass, however, belong to the described product specification. A clear separation of these details makes it easier to prepare an unambiguous enquiry.

05

Assessing the intended opening carefully

As the tilt-and-turn sash moves inwards, assess the intended opening not only by size but also spatially. Establish the measurements relevant to the project carefully and record what each value refers to. The frame dimensions in the product specification do not replace this process, because they describe individual components rather than the finished external size of your made-to-measure window.

Also consider the area on the room side that the sash requires when turning. A window board, reveal, radiator, fittings, furniture, curtains or other elements may affect practical use. Include these possible obstructions as checkpoints, so the inward movement is assessed in your actual plan rather than only on a flat façade elevation.

Handle accessibility can also form part of the assessment. Consider from which position you will normally operate the window and whether the selected single- or double-sash composition suits that use. The area immediately around the sash is relevant for the tilt position too. Do not assume that a suitable elevation automatically means suitable spatial use.

For existing building openings, irregular edges, different reference planes or differing internal and external views can make documentation more difficult. A labelled sketch can help assign measurement points clearly. If you use photographs, they should show the opening and adjoining building elements clearly. Photos do not replace measurements, but they can make the spatial situation easier to understand.

Finally, compare the preferred sash division with the space actually available for operating movement. Only then should colour and handle be finalised as visual details. This keeps the essential usability of the intended opening as the starting point, with design coordination built around it. If uncertain, have the specific building situation assessed professionally before using binding project dimensions.

Colour, oak and visual composition

Oak provides the material basis for this window. A colour choice is available for its visible finish. This lets you place the window within your project’s colour concept without assuming a different timber species. Name the required colour clearly, so it does not have to be inferred only from surrounding photos or general descriptions such as “to match the façade”.

Start visual coordination with the larger surfaces and lines: the wall surface, window frame, glazing and single- or double-sash division. Smaller details, such as the handle, can follow afterwards. This is not a fixed design rule, but it helps prevent the effect of one detail from being considered separately from the complete window composition.

Alongside colour and made-to-measure sizing, the handle is an explicitly available purchase choice. It contributes both to operation and visible design. When selecting it, consider whether it should stand out intentionally or blend discreetly into the overall appearance. State your handle preference clearly in the enquiry.

A double-sash arrangement creates more visible division points than a single-sash version. The same frame colour can therefore look different depending on the arrangement. A bold colour choice can make frame lines more prominent, while a restrained choice can visually connect them more closely with their surroundings. Consider colour and sash division together within the relevant architectural setting.

If the window forms part of a series of different openings, a shared façade elevation can make the decision easier. Check axes, spacing and the repetition of frame lines. Adjacent products do not need to be technically identical to relate visually. What matters is that you record the required colour and handle choice separately for this particular fire-rated window, rather than deriving them from other windows or doors.

Comparing related windows and doors

When selecting products, first establish which function and opening type are required at each position. This EI30 window is oak and opens inwards as a tilt-and-turn design. The related range also includes outward-opening windows, combination windows, non-opening fixed glazing and single patio doors. This allows the various openings in a project to be planned with an appropriate product type.

The outward-opening passive-house window differs from the fire-rated window in opening direction, sash type, material, glazing and frame construction. The combination window, in turn, offers several timber versions, some with aluminium cladding, as well as combinations within one window element. Both product types are independent options for different planning needs and should be selected according to their individual specifications.

Fixed-glazed windows do not open and are useful as a comparison where no operating function is needed. In addition to the classic shape, round, semicircular, triangular and sloping fixed-glazing versions are available for orientation. Depending on the product type, pine, oak or versions with aluminium cladding are specified. Glazing and frame dimensions also differ from the EI30 window.

For access to a terrace, single-leaf, outward-opening patio doors are available in regular and historic styles. Both are made to measure and allow a choice of colour and handle, but have their own door hardware, glazing options and designs. Therefore list windows and doors as separate positions in your project overview, using the full product name for each.

When comparing related products, focus particularly on opening type, material, glazing, available design and suitable purchase choices. A consistent colour concept can visually link different elements, while dimensions and technical product specification must be set separately for each position. The following related products provide an overview of the available alternatives: Super Low Uw passive-house window, outward opening, Combination window, Window with fixed glazing, Round window with fixed glazing, Semicircular window with fixed glazing, Triangular and sloping window with fixed glazing, Single-leaf, outward-opening patio door, Historic-style, single-leaf, outward-opening patio door.

Preparing your enquiry in a few steps

Start with the full product name, “EI30 fire-rated window, inward opening”. This makes it clear which window your details concern. Then choose the stated single- or double-sash arrangement. If several positions are planned, give each one a short, clear position name and assign the desired composition separately to every position.

Next, compile the carefully established project dimensions. Label every measurement so its reference remains clear, and distinguish your project values from the product’s fixed component dimensions. A simple sketch using the same position names can make assignment easier. Avoid unlabelled rows of figures, as they can easily be misunderstood without a reference level.

Then record the desired colour. Describe it as clearly as possible and do not rely solely on the representation in a photo or on a screen. Next, add your handle preference. As colour and handle are available choices, both should appear as deliberate decisions rather than merely being inferred from a general style description.

Finally, summarise the relevant information for each window position: product name, arrangement, project dimensions, colour and preferred handle. Add special questions in a separate list so they are not lost among the dimensions. If you include several related product types, list them under their respective product names and do not mix their properties with those of the fire-rated window.

Before sending, check that terms are used consistently. In particular, “outer frame”, “sash frame”, “project dimension” and “sash division” should not appear interchangeable. A clearly structured enquiry enables a focused discussion about the choices actually available, without treating fixed product specifications as open selections. It creates a traceable basis for further coordination of your made-to-measure window.

Is the fire-rated window available made to measure?

Yes. Made-to-measure manufacture is one of the available options. Send us the carefully established project dimensions and your preferred version. The stated frame dimensions describe individual components and must not be treated as the overall size of the ordered window.

What material is the window made from?

The window is made from oak. This material forms the natural basis of its design and can be considered when coordinating colour, wall surfaces and other building elements.

Can I choose a colour?

Yes. A colour choice is available, allowing the window to be designed around the relevant project. State the exact colour you require in your enquiry so the intended appearance can be recorded clearly.

Can the handle be selected?

Yes. In addition to the dimensions and colour, you can select the handle. Consider both everyday operation and its visual effect on the oak window. Send your handle preference together with the preferred single- or double-sash arrangement.

Is the window CE marked?

Yes, the EI30 fire-rated window is CE marked. Use the complete product name in your enquiry so that your dimensions, preferred sash arrangement, colour and handle selection can be assigned clearly to this inward-opening window.

How long is the warranty?

This product has a five-year warranty. Keep order-specific details and documents organised so that the particular window can be identified clearly later. The warranty statement applies to this described product.

What glazing is used?

The window has double-glazed insulated glass with a heat-reflective coating. The glazing seals are silicone.

Is the fire-rated window available with one or two sashes?

This product is available as a single inward-opening sash design or as a double inward-opening EI30 window. The most suitable version depends on the project dimensions, the movement space available inside and the desired façade appearance.
