Operation and everyday use

On the Kombi casement window, the sash is the moving part of the composition and opens outwards. The adjacent pane remains fixed. This division is straightforward in everyday use: you operate the sash while the fixed pane remains an unchanged part of the window. The combination suits projects requiring one continuous window area with both opening and fixed sections.

Because the sash opens outwards, its travel area should remain clear in daily use. Consider items directly in front of the window as well as nearby building elements, reveals, railings or planting. This applies to the full opening movement and to use while the sash is open. Check the outside early alongside the intended dimensions, installation position and window access.

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

The fixed glazed pane requires no operation. Its effect lies in calmly complementing the opening sash and in the shared design of both sections. Depending on the selected glazing-bar pattern, the fixed pane can remain deliberately understated or echo lines from the sash. For everyday use, consider separately the sash’s free movement and accessibility, and the desired visual relationship between opening and fixed panes.

Before operating the window, check that the external swing area is clear. This is especially useful when planting or other objects near the window have changed.

02

Construction, component dimensions and fittings

The construction combines an outer frame, the frame of the moving sash and a fixed glazed pane. Pine and oak are available as timber options. Coordinate this choice with the desired colour, glazing-bar pattern, handle and existing building elements. SPILKA and IPA fittings are included in the product specification.

All numerical product details are collected here: the outer frame has a component dimension of 105 × 57 mm, while the sash frame measures 76 × 65 mm. Installation holes measure 14 mm. This product has a 5-year guarantee. Double or triple insulating glass is available. These values describe individual components and features; they are not the overall window depth, width or height.

The window is CE marked. The key details for specifying your version are dimensions, timber species, colour, handle, glazing and the selected glazing-bar pattern. Record these separately in your enquiry so the arrangement of the fixed pane and outward-opening sash is described unambiguously.

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

The fixed glazed pane and sash form one combined unit. Your enquiry should therefore clearly describe not only the overall size but also the intended division. A simple sketch showing the fixed pane, sash and opening direction can support your written details. It makes clear how you understand the window from the relevant viewing side.

05

Assessing the intended window opening

As the window is made to measure, a reliable enquiry starts with careful assessment of the intended structural opening. Measure the opening in several places, as existing walls and older junctions can be irregular. Record values so it remains clear where each measurement was taken. Also establish which side your sketch or description is viewed from.

Next, check the window surroundings. Outside, the sash needs a clear movement area. Eaves, reveals, railings, planting or other adjacent elements may matter for detailed planning. Inside, the main consideration is whether the handle remains easy to reach. A sill, benchtop, furniture or other fittings can affect how comfortably you can operate the sash.

Then consider the building junction. The condition of the opening, adjoining materials and existing linings should be apparent in your documentation where they could affect dimensional decisions. For a replacement window, it can 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 the fixed pane and sash must also be clear. Terms such as “left” and “right” can be ambiguous if the viewing side is not stated. Mark the inside and outside, as well as the outward-opening sash, on a sketch. Add the selected glazing-bar pattern so the lines are allocated to the correct section. A clear drawing reduces follow-up questions when preparing your product enquiry.

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

06

Colour, timber and the overall visual composition

The historic character of this window results from the interplay of frame material, pane 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 colour, glazing-bar pattern and handle with the chosen timber and wider design concept.

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

The Kombi principle brings a fixed pane and an operable sash together in one window composition. Glazing bars can divide the two areas differently or carry recurring lines across both glass surfaces. An unbarred fixed pane beside a divided sash emphasises the operable area, while vertical or crossed lines can visually link both sections more closely. The applicable choice is one of the available, defined glazing-bar patterns.

Black rubber seals provide the glazing seal, while frame colour, timber surfaces and glazing-bar arrangement determine visual coordination. SPILKA and IPA fittings form part of the technical specification, and you can also select a handle. Record your handle preference together with colour, timber species and glazing-bar pattern so technical fittings and visible design choices remain clearly distinguished in your enquiry.

A useful decision process is to first describe the desired overall effect in a few words: calmer, more divided, aligned with existing lines, or intended as an independent composition. Then assign a suitable named glazing-bar pattern and add the timber species, colour and handle preference. This creates a clear selection in which every visible feature has its own role rather than being inferred from technical details.

Comparing related window types and patio doors

The Kombi casement window combines a fixed glazed pane with an outward-opening sash. When comparing related products, first consider opening direction, number of sashes, method of operation and intended use. Then review material, glazing, glazing-bar pattern and other specification details for each window or patio door. This helps you choose the right product type before confirming dimensions, colour and handle.

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

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

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

Use the following list as a starting point for comparing the related products shown here. Open each product to review only its own features, design and available options: Single-sash reversible window with vertical pivot axis, outward opening, Double-sash reversible window with vertical pivot axis, outward opening, Single-sash inward-opening window, Double-sash inward-opening window, EI30 fire-rated window, inward opening, EI30 fire-rated reversible window, outward opening, Single-sash outward-opening patio door, Historic-style single-sash outward-opening patio door.

A clear enquiry in a few steps

Start by clearly naming your project and specifying the historic “Kombi” casement window. Include a sketch of the intended opening that marks inside and outside, the fixed pane, sash and opening direction. Add your carefully taken dimensions, including where they were measured. This keeps the structural opening and desired window clearly separate.

Then select one of the named glazing-bar patterns. Rather than simply writing “with glazing bars”, describe the lines in the fixed pane and sash separately. If using a sketch, it should match your written description. This makes clear whether the fixed pane 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 handle preference. These details concern different parts of the configuration and should each have their own line. If you are still deciding on one feature, identify it as an open choice rather than listing several conflicting details without explanation.

Add installation information only where it is important for understanding the project. This may include adjacent building elements, an unusual opening shape or handle access. Separate observed conditions from desired product features. A sentence such as “There is an adjacent building element outside” describes the situation; any resulting dimensional or planning decision should be assessed separately.

Finally, check that all details use the same viewing side and that the fixed pane and sash are clearly assigned. Also confirm that dimensions, glazing-bar pattern, timber species, colour, glazing and handle preference are included. A short, organised enquiry is more helpful than a long description using 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 useful enquiry, we need the dimensions of the intended opening. Check these carefully in several places and let us know whether particular building junctions or adjacent elements should be considered.

Which timber species are available?

Pine and oak are available. Both materials support the distinctive character of a timber window. You can assess which timber is right for your project by considering the desired design, existing building elements and your personal preference.

Can I choose a colour for the window?

Yes. A choice of colours is among the available ordering options. Consider the façade, 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 available for this window?

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

What does “Kombi” mean for this window?

The Kombi principle combines a fixed glazed pane with an outward-opening sash. The precise glazing-bar arrangement follows one of the named design patterns. The fixed pane and sash can therefore appear calm or be divided by horizontal and vertical glazing bars.

Are different glazing-bar layouts available?

The range includes several defined patterns, from an unbarred fixed pane with an unbarred sash to arrangements 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. Include your handle preference with the dimensions, timber species, colour, glazing and glazing-bar pattern. This keeps all design and functional details together in one enquiry that can be readily checked.

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, colour, glazing, handle and glazing-bar pattern can be clearly assigned to the window requested.
