Operation and everyday use

On the Kombi casement window, the sash forms the moving part of the composition and opens outwards. The adjacent section remains fixed glazed. In everyday use, this division of functions is easy to understand: you operate the sash while the fixed light remains an unchanged part of the window. The combination suits projects where one continuous window area should contain both an opening and a fixed section.

As the sash opens outwards, its movement area should remain clear during everyday use. Consider objects immediately in front of the window as well as adjoining building elements, reveals, railings or planting. This applies both to the full opening movement and when using the window with the sash open. Check the outside early on in relation to the intended dimensions, installation position and accessibility of the window.

The window position also matters for comfortable use. Consider where you will reach the handle and operate the sash from. A window above a deep worktop, for example, has different accessibility requirements from one in a freely accessible wall opening. Include the available handle in your configuration and describe the installation situation in your enquiry if it is relevant to operation.

The fixed glazed light requires no operation. Its effect lies in quietly complementing the opening sash and in the shared design of both sections. Depending on the selected glazing-bar pattern, the fixed light can remain deliberately understated or pick up the sash lines. For daily use, consider two aspects separately: free movement and access to the sash, and the desired visual relationship between the moving and fixed glazed sections.

Before each use, check that the outer movement area is clear. This is especially useful if planting or other objects near the window have changed.

02

Construction, component dimensions and fittings

The construction combines an outer frame, the moving sash frame and a fixed light. Pine and oak are available as timber options. Coordinate the choice with your preferred colour, glazing-bar design and handle, as well as existing building elements. The product is fitted with hardware from SPILKA and IPA.

All numerical product details are grouped here: the outer frame has component dimensions of 105 × 57 mm, and the sash frame measures 76 × 65 mm. Installation holes measure 14 mm. This product has a 5-year guarantee. Glazing is available as double- or triple-glazed insulating glass. These values describe individual components and characteristics; they are not the depth, width or height of the complete window.

The window is CE marked. The key features for specifying your version are the size, timber species, colour, handle, glazing and selected glazing-bar pattern. Keep these features separate in your enquiry so the composition of fixed light and outward-opening sash is described unambiguously.

When considering frame dimensions, it is important to distinguish between a component and the complete product. The stated values relate to the outer frame and sash frame. The actual ordered size of the window depends on the intended opening and your measurement enquiry. Do not transfer component dimensions directly as finished external dimensions to your project. Keep measured opening values and product component data separate in your notes.

The combination of fixed glazed light and sash forms one complete unit. For an enquiry, this means that not only the overall size but also the desired division should be described clearly. A simple sketch marking the fixed light, sash and opening direction can complement your written details. This clarifies how you understand the window from the relevant viewing side.

05

Assessing the intended window opening

As the window is offered made to measure, a reliable enquiry begins with careful consideration of the intended structural opening. Measure the opening at several points, as existing walls and older connections may be uneven. Record the values so it remains clear where each measurement was taken. Also define from which side your sketch or description is viewed.

Next, check the surroundings of the window. On the outside, the sash needs a clear movement area. Roof overhangs, reveals, railings, planting or other adjoining elements may be relevant to the specific planning. On the inside, the main consideration is whether the handle remains easy to reach. A sill, worktop, furniture or other fittings can affect how comfortably you can operate the sash.

Then consider the structural connection. The condition of the opening, adjoining materials and existing linings should be visible in your documents if they could influence the final dimensions. For a replacement window, it may be useful to document the existing situation separately from the desired product dimensions. Avoid transferring dimensions from old components directly to the new window without checking them.

The orientation of fixed light and sash must also be clear. Terms such as “left” and “right” can be ambiguous if the viewing side is not specified. Mark the inside and outside, as well as the outward-opening sash, on a sketch. Add the desired glazing-bar pattern so the lines are assigned to the correct section. A clear presentation reduces follow-up questions when preparing your product enquiry.

This preliminary check does not replace a project-specific structural assessment, but it provides an organised basis. It separates measured values, observed conditions and personal design preferences. This is especially useful for historic buildings, where openings, connections and neighbouring elements are not always completely uniform. The clearer your starting details, the more precisely timber, colour, glazing, handle and glazing-bar pattern can be described.

06

Colour, timber and overall visual composition

The historic effect of this window comes from the interplay of frame material, field division, glazing-bar lines and colour. Pine and oak are available as timber options. When deciding, consider both the desired expression of the building and existing windows, doors and visible timber elements. You can then coordinate the colour, glazing-bar pattern and handle with the chosen timber and the overall design concept.

A choice of colours is also among the available ordering options. Colour can closely connect the window with a facade or make its division more prominent. For an existing building, you can use existing windows, doors, cladding and other visible components as reference points. Within a new design concept, the window colour can form part of an overall material and colour plan. State specific colour preferences clearly in your enquiry.

The Kombi principle brings together a fixed light and an operable sash in one window composition. Glazing bars can divide the two sections differently or continue recurring lines across both glass areas. An unbarred fixed light beside a divided sash highlights the operable section, while vertical or crossed lines can visually connect both sections more closely. The deciding factor is one of the available fixed glazing-bar patterns.

The black rubber seals provide glass sealing, while frame colour, timber surfaces and glazing-bar layout determine the visual coordination. Technical equipment includes hardware from SPILKA and IPA; you can also choose a handle. Record the preferred handle with the colour, timber species and glazing-bar pattern, so technical equipment and visible design choices remain clearly distinct in your enquiry.

A useful approach is first to describe the desired overall effect in a few words: calm, more divided, guided by existing lines or intended as an independent composition. Then assign a suitable named glazing-bar pattern and add the timber species, colour and preferred handle. This creates an understandable selection in which every visible feature has its own role and does not need to be derived from technical details.

Comparing related window types and patio doors

The Kombi casement window combines a fixed glazed light with an outward-opening sash. When comparing related products, start with opening direction, number of sashes, operating method and intended use. Then check material, glazing, glazing-bar patterns and further features directly on each window or patio door. This helps you choose the right product type before deciding on dimensions, colour and handle.

Outward-opening alternatives include single- and double-sash windows with a vertical pivot axis. For projects where sashes should move inwards, the related range also includes single- and double-sash tilt windows. Compare the required movement area and preferred number of operable sashes with the combination of fixed light and outward-opening sash in this historic window.

If your project requires a window with EI30 product classification, the related range includes an inward-opening version and an outward-opening fire-rated pivot window. Both are made from oak and have double-glazed insulating glass with a heat-reflective coating. Compare these products separately with your project requirements, as the Kombi casement window described here is not offered as an EI30 product.

For a walk-through route outdoors, compare the single-sash outward-opening patio doors instead. Alongside the general version, there is a historic-style option. Both are available in pine or oak with double- or triple-glazed insulating glass; depending on the version, panelled designs are also provided. The general patio door additionally offers timber variants with aluminium cladding.

Use the following selection as a starting point for comparing approved related products. Open the relevant product to check only its own features, design and available choices: Single-sash outward-opening window with vertical pivot axis, Double-sash outward-opening window with vertical pivot axis, Single-sash inward-opening window, Double-sash inward-opening window, EI30 inward-opening fire-rated window, EI30 outward-opening fire-rated pivot window, Single-sash outward-opening patio door, Historic-style single-sash outward-opening patio door.

A clear enquiry in a few steps

Start with a clear description of your project and name the historic-style “Kombi” casement window. Include a sketch of the intended opening marking the inside and outside, fixed light, sash and opening direction. Add your carefully recorded dimensions and state where they were taken. This keeps the structural opening and desired window clearly separate.

Then choose one of the named glazing-bar patterns. Do not simply write “with glazing bars”; describe the lines in the fixed light and sash separately. If you use a sketch, it should agree with your written details. This shows whether the fixed light remains unbarred, receives a vertical division, or includes horizontal and vertical lines.

Next, note the requested options: pine or oak, your colour preference, preferred glazing construction and preferred handle. These details concern different parts of the configuration and should each be given on a separate line. If you are still considering an option, mark it as an open decision rather than placing several conflicting details beside one another without comment.

Add notes about the installation situation only where they are important for understanding. These may include adjoining components, an unusual opening shape or access to the handle. Separate observed conditions from desired product properties. A sentence such as “There is an adjoining component outside” describes the situation; the resulting dimension or planning decision should be checked separately.

Finally, check whether all details use the same viewing side and whether the fixed light and sash are assigned unambiguously. Also confirm that dimensions, glazing-bar pattern, timber species, colour, glazing and preferred handle are included. A short, organised enquiry is more useful than a long description with inconsistent terms. This sequence provides a clear basis for further discussion of your made-to-measure Kombi casement window.

Is the Kombi casement window available made to measure?

Yes. The window is offered made to measure. For a meaningful enquiry, we need the dimensions of the intended opening. Check them carefully at several points and also tell us whether particular structural connections or adjoining components need to be considered.

Which timber species are available?

Pine and oak are available. Both materials support the distinctive character of a timber window. You can decide which timber suits your project based on the intended design, existing building elements and personal preference.

Can I choose a colour for the window?

Yes. A choice of colours is among the available ordering options. Consider the facade, existing windows, doors and visible timber elements when deciding. Include the specific colour in your enquiry so your design preference can be recorded clearly.

Which glazing is provided for this window?

Double- or triple-glazed insulating glass is available. Both versions have a heat-reflective coating, warm-edge spacer and argon gas filling. State your preferred version in the enquiry so it can be considered with the other product features.

What does “Kombi” mean for this window?

The Kombi principle joins a fixed glazed light with an outward-opening sash. The exact glazing-bar layout follows one of the named design patterns. The fixed light and sash can therefore appear calm or divided by horizontal and vertical glazing bars.

Are different glazing-bar layouts available?

The range includes several fixed patterns, from an unbarred fixed light with an unbarred sash to layouts with horizontal and vertical glazing bars. The available patterns cover both sections in different combinations and are explained in the design section of this product description.

Can I choose a handle?

Yes. A choice of handle is among the available ordering options. State your preferred handle together with dimensions, timber species, colour, glazing and glazing-bar pattern. This keeps all design and functional details together in one easily checked enquiry.

How long is the guarantee for the Kombi casement window?

The “Kombi” casement window has a five-year guarantee. Include the exact product name and selected configuration in your enquiry so dimensions, timber species, colour, glazing, handle and glazing-bar pattern are clearly assigned to the window requested.
