01

Operation and everyday use

Built as an inward-opening tilt-and-turn unit, the sash has two distinct operating positions: turn mode opens it fully, while tilt mode provides a limited opening. The appropriate position depends on the situation in everyday use. Combining both movements within one operating system removes the need for separate window elements to provide these two forms of use.

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

Because the sash opens inwards, operation takes place from inside the room. This is particularly relevant to personal use: consider how you will reach the window and what routines develop around the handle. The physical space is considered separately in the section on the intended opening. In everyday use, guide the sash carefully and ensure that no objects are in its immediate path.

For regular care, clean visible surfaces and the handle using methods suitable for each material. Avoid using aggressive or abrasive products simply as a matter of routine. Glazing, timber surfaces, silicone seals and hardware are different components and may not require the same treatment. Careful operation and material-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 figures explicitly describe the stated frame components. They are neither the width and height of the complete window nor a finished order size for the wall opening. Overall dimensions are set for the particular project through the made-to-measure service.

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

Double insulating glazing with a heat-reflective coating and silicone glazing seals are fixed elements of the product specification. The EI30 fire-rated window is CE marked and supplied with a five-year warranty. Together with the oak construction, Roto Frank hardware and stated frame and drill-hole dimensions, these features form the basis for coordinating your project.

When making an enquiry, it is useful not to convert component dimensions into an assumed overall size. Instead, provide the dimensions 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 drawings or several openings are involved.

Keep fixed product specifications separate from your personal choices. 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 insulating glazing are part of the described product specification. Separating these details clearly 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 dimensions but also spatially. Determine the measurements relevant to the project carefully and record what each value refers to. 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 room-side area needed when the sash turns open. Window sills, reveals, radiators, fittings, furniture, curtains or other elements can affect practical use. Include such possible obstructions in your checks, so the inward movement is assessed in your actual plan rather than only in a flat façade view.

Handle access can also form part of the assessment. Consider from which position you would normally operate the window and whether the selected single- or double-sash layout suits this. The immediate area around the sash is also relevant in tilt position. Do not assume that a suitable elevation automatically provides suitable spatial use.

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

Finally, compare the desired sash arrangement with the space actually available for operation. Only then should colour and handle be finalised as visual details. This keeps the basic usability of the intended opening as the starting point, with visual coordination built around it. If uncertain, seek a professional assessment of the specific building situation before using binding project dimensions.

Colour, oak and visual composition

Oak provides the material basis of this window. A colour choice is available for its visible finish. This lets you place the window within your project’s colour scheme without assuming a different timber species. State the desired colour clearly, rather than relying on surrounding photos or broad descriptions such as “to match the façade”.

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

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

A double-sash design creates more visible division points than a single-sash version. The same frame colour can therefore appear differently depending on the arrangement. A strong colour choice may make the frame lines more prominent, while a restrained finish can connect them more closely with their surroundings. Consider colour and sash division together in their architectural setting.

If the window forms part of a series of different openings, a shared façade elevation can make the decision easier. Use it to review axes, spacing and repeated frame lines. Adjacent products do not need to be technically identical to relate visually. What matters is recording the chosen colour and handle for this specific fire-rated window separately, rather than inferring them from other windows or doors.

Comparing related windows and doors

When choosing products, first establish which function and opening type are required at each location. This EI30 window is made from 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 different openings in a project to be planned with a suitable 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 offers different timber options, sometimes with aluminium cladding, as well as combinations within one window element. Both are independent options for other planning needs and should be selected according to their own specifications.

Fixed-glazed windows do not open and are useful for comparison where no operating function is needed. Classic, round, semicircular, triangular and angled fixed-glazing forms are available for orientation. Depending on the product type, pine, oak or aluminium-clad versions are provided. Glazing and frame dimensions also differ from the EI30 window.

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

When comparing related products, focus especially on opening type, material, glazing, available styling and suitable purchasing choices. A consistent colour scheme can connect different elements visually, while dimensions and technical product specification must be established separately for each position. The following related products provide an overview of 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 angled windows with fixed glazing, Single outward-opening patio door, Historic-style single outward-opening patio door.

Prepare your enquiry in a few steps

Start with the complete product name, “EI30 fire-rated window, inward-opening”. This makes it clear which window your details refer to. Then choose the stated single- or double-sash configuration. If several positions are planned, give them short, clear names and assign the required composition separately to each position.

Next, compile the project dimensions you have determined carefully. Label every dimension so its reference is clear, and distinguish your project values from the product’s fixed component specifications. A simple sketch using the same position names can aid identification. Avoid unlabelled sequences of numbers, as they can easily be misunderstood without a reference plane.

The next step is to record the desired colour. Describe it as clearly as possible rather than relying only on a photograph or screen display. Then add your handle preference. As colour and handle are available options, both should be intentional decisions rather than assumptions drawn from a general style description.

Finally, summarise the relevant information for each window position: product name, configuration, project dimensions, colour and handle preference. Add particular questions to a separate list so they do not get lost among the measurements. If including several related product types, list them under their own product names and do not mix their properties with those of the fire-rated window.

Before sending, check that terms are used consistently throughout. In particular, “outer frame”, “sash frame”, “project dimension” and “sash arrangement” should not appear interchangeable. A clearly structured enquiry supports a focused discussion of the choices that are actually available, without accidentally treating fixed product specifications as open options. This provides 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 production is one of the available options. Send us the project dimensions you have carefully determined and the required configuration. The stated frame dimensions describe individual components and are not equivalent to the overall dimensions of the ordered window.

What material is the window made from?

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

Can I choose a colour?

Yes. A choice of colour is available, allowing the window to be visually coordinated with the project. It is best to state the specific colour in your enquiry so the required appearance can be recorded clearly.

Can the handle be selected?

Yes. Alongside dimensions and colour, you can also select the handle. Consider both everyday operation and its visual effect on the oak window. Send your handle preference together with the required single- or double-sash configuration.

Is the window CE marked?

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

How long is the warranty?

This product is supplied with a five-year warranty. Keep order-specific information and documentation organised so the particular window can be identified later. The warranty statement applies to this described product.

What glazing is used?

The window has double insulating glazing 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 a double inward-opening EI30 window. The more suitable version depends on the project dimensions, available room-side operating space and desired façade appearance.
