01

Operation and everyday use

The sash has an inward-opening tilt-and-turn design. It offers two distinct modes: the turn position opens the sash fully, while the tilt position creates a limited opening. The most suitable position depends on the situation. By combining both movements in one operating system, the tilt-and-turn mechanism avoids the need for separate window elements for these uses.

Move the handle deliberately into the required position and guide the sash in a controlled manner. Where possible, change the handle position only after completing the relevant opening movement. As the handle is selectable, you can choose an option that feels comfortable in use and complements both the oak frame and your selected colour.

Because the sash opens inward, its operating movement takes place inside the room. Consider how you will reach the window and the routine around using its handle. The spatial assessment is covered separately in the section on the intended opening. In daily use, guide the sash carefully and ensure that no objects obstruct its immediate path of movement.

For regular care, clean visible surfaces and the handle using methods suited to each material. Do not use aggressive or abrasive products merely through habit. Glazing, timber surfaces, silicone seals and fittings are different components and may need different 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 at 82 × 90 mm, and the sash frame also has a component dimension of 82 × 90 mm. These figures specifically describe the stated frame components. They are not the width and height of the complete window, nor a finished order size for the wall opening. Overall dimensions are set for the individual made-to-measure project.

A measurement of 14 mm is specified for the mounting holes. The fittings are from Roto Frank. This brand identifies the specified fittings, not a choice between fitting brands. Likewise, oak is the fixed material for this product version rather than one of several material alternatives. This clear distinction helps separate component specifications from genuinely available purchase choices.

The fixed product specification includes heat-reflective double-pane insulating glass and silicone glazing seals. The EI30 fire-rated window is CE marked and supplied with a five-year guarantee. Together with the oak construction, Roto Frank fittings, and the stated frame and mounting-hole dimensions, these features form the basis for detailed project coordination.

When making an enquiry, do not convert component dimensions into an assumed overall size. Instead, state the dimensions established for your project separately and identify exactly what each refers to. This makes clear which figures 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 choices. Colour, handle and made-to-measure dimensions can be adapted to your project. Oak as the frame material, Roto Frank fittings, silicone seals and coated double-pane insulating glass are part of the described product version. A clear separation of these details makes an unambiguous enquiry easier to prepare.

05

Assessing the intended opening carefully

As the tilt-and-turn sash moves inward, assess the intended opening spatially as well as dimensionally. Establish all relevant project measurements carefully and record what each value refers to. Frame dimensions in the product specification do not replace this work, because they describe individual components rather than the finished external size of your made-to-measure window.

Also consider the indoor area needed when the sash turns open. A windowsill, reveal, radiator, fittings, furniture, curtains or other items can affect practical use. Include such potential obstructions in your checks so that inward movement is assessed for your real project, rather than only on a flat façade drawing.

Handle accessibility can also form part of the assessment. Consider where you will normally operate the window and whether the selected single- or double-sash composition suits this. The space immediately around the sash also matters in the tilt position. Do not assume that a suitable elevation view automatically means the spatial use will be suitable.

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

Finally, compare the desired sash layout with the area 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 on top. If uncertain, seek professional assessment of the actual building situation before using final project dimensions.

Colour, oak and visual composition

Oak forms the material basis of this window. A colour choice is available for its visible finish. This allows the window to fit your project’s colour scheme without assuming a different timber species. State the requested colour clearly, rather than relying on surrounding photographs or broad descriptions such as “to match the façade”.

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

Alongside colour and made-to-measure dimensions, the handle is an explicitly available choice. It contributes both to operation and visible design. When selecting it, consider whether it should stand out deliberately or blend discreetly 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 look different depending on the layout. A bold colour can emphasise frame lines, while a restrained choice can blend them more closely with the surroundings. Consider colour and sash division together within the relevant architectural setting.

If the window is part of a series of different openings, a shared façade elevation can simplify the decision. Review axes, spacing and repeated frame lines. Neighbouring products need not be technically identical to relate visually. What matters is recording the desired colour and handle for this specific fire-rated window separately, rather than deriving them from other windows or doors.

Comparing related windows and doors

When selecting products, first establish which function and opening type each position needs. This EI30 window is oak and opens inward as a tilt-and-turn design. The related selection also includes outward-opening windows, combination windows, non-opening fixed glazing and single-leaf patio doors. This allows each project opening 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, in turn, offers different timber versions, some with aluminium cladding, and combinations within one window element. Both are independent options for different planning needs and should be selected according to their own specifications.

Fixed-glazed windows do not open and provide a useful comparison where no operating function is needed. Alongside the classic form, round, semi-round, triangular and sloping fixed-glazing designs are available for consideration. Depending on the product type, pine, oak or aluminium-clad versions are specified. Their glazing and frame dimensions also differ from those of the EI30 window.

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

When comparing related products, focus on opening type, material, glazing, available styling and the relevant purchase options. A consistent colour concept can visually connect different elements, while dimensions and technical construction must be established separately for every 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, Semi-round window with fixed glazing, Triangular and sloping windows with fixed glazing, Single-leaf outward-opening patio door, Historic-style single-leaf outward-opening patio door.

Prepare your enquiry in a few steps

Start with the full product name, “EI30 fire-rated window, inward opening”. This makes clear which window your information concerns. Then select the stated single- or double-sash layout. If several positions are planned, give them short, unambiguous names and assign the desired composition separately to each position.

Next, gather the carefully established project dimensions. Label every measurement so its reference remains clear, and distinguish project values from fixed product component information. A simple sketch using the same position names can make this easier to follow. Avoid unlabelled rows of figures, as they can easily be misunderstood without a reference plane.

Then record the requested colour. Describe it as clearly as possible and do not rely solely on a photograph or screen display. Add your handle preference afterwards. Because colour and handle are available options, both should appear as considered choices rather than being inferred from a general description of style.

Finally, summarise the relevant information for every window position: product name, layout, project dimensions, colour and handle preference. Add specific questions in a separate list so they are not lost among measurements. If you include several related product types, list each under its own product name and do not mix their characteristics 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 layout” should not be treated as interchangeable. A clearly structured enquiry enables focused discussion of the options actually available without accidentally presenting fixed specifications as open choices. 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 production 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 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 colour choice is available, allowing the window to be visually aligned with the project. Include the exact colour you want in your enquiry where possible, so the intended appearance can be recorded clearly.

Can the handle be selected?

Yes. In addition to 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 requested single- or double-sash layout.

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, requested sash layout, colour and handle choice can be assigned clearly to this inward-opening window.

How long is the guarantee?

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

Which glazing is used?

The window has double-pane insulating 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-sash inward-opening design and as a double-sash inward-opening EI30 window. The better option depends on project dimensions, available room-side operating space and the desired façade appearance.
