Operation and everyday use

The single sash opens outwards as a casement window. Its direction of movement therefore differs from windows whose sashes swing into the room. In daily use, the inside area in front of the window is not affected by the movement of the open sash. This can assist room planning, but does not confirm suitability for any particular furniture arrangement or window treatment. The key consideration is always how the window will be installed and used in your specific situation.

For comfortable everyday operation, consider early on from which position you will use the sash. The handle is selectable and can be chosen for practical reasons as well as to suit the window’s design. Please state your handle preference clearly in your enquiry. SPILKA and IPA are specified as fittings; they form part of the technical equipment and are not separate purchase choices.

How often the window is opened and how easily the handle should be reached depend on the room and your habits. Check whether furniture, deep internal reveals or window dressings could obstruct access to the operating handle. There should also be enough clear space outside for the sash to open. This brings interior planning and the building situation into consideration before you order.

Treat timber surfaces, glass and rubber seals as different materials when cleaning and maintaining the window. Select cleaning products and tools suitable for each surface, avoiding aggressive products or abrasive tools. Guide the sash carefully when opening and closing, and operate the handle without unnecessary force. Also follow the care instructions applicable to the selected timber and colour finish.

02

Construction and component dimensions

The window comprises an outer frame and a single sash frame. The outer frame is the fixed frame element, while the sash frame holds the movable window sash. The component dimensions and installation-hole size are listed together in the facts overview. These measurements expressly refer to the named components and should not be read as the overall depth, width or height of the complete window.

Pine and oak are available for the timber construction. This choice affects more than the material name: it also shapes the window’s natural appearance. Timber has its own grain and may vary in visible texture. Such natural differences are inherent to the material and should be considered when coordinating with existing timber elements. A choice of colour is also available, allowing timber species and the desired colour effect to be considered together.

The outer frame, sash frame, glazing, seals and fittings together form the window’s construction. SPILKA and IPA are specified for the fittings. Timber species, colour and handle, by contrast, are features you can choose in your enquiry. This distinction helps keep technical product information and personal design preferences clearly organised.

For a made-to-measure window, component dimensions and overall dimensions must be distinguished. Profile information explains the construction of the frame elements, while the manufactured window size is tailored to the intended opening. Individual profile values alone should therefore not be used for planning or installation. A complete dimensional assessment requires details of the actual opening and building situation.

The window is CE marked and offered with a five-year guarantee. For planning, both details should be considered separately from project-specific requirements. If your project needs particular technical values or documents, please include these as specific questions in your enquiry. This allows the appropriate version to be considered against the requirements of the building.

05

Assessing the intended window opening

Before making an enquiry, assess the actual opening carefully. Because the sash opens outwards, more than the opening dimensions must be considered. The area outside also needs to be included in the planning. Reveals, external sills, railings, planting, fittings on other elements or projecting construction details may affect the situation. Whether such elements interfere must be checked against the actual arrangement.

Measure the opening at several suitable points and note any visible variations. In older buildings, edges, reveals and junctions can be irregular. A single quickly taken measurement may therefore not represent the existing situation sufficiently. Also record whether this is an existing opening, a planned new-build junction or replacement of an existing window. This information helps place the dimensions in context.

Then check the movement zone of the outward-opening sash. What matters is the space genuinely available along its opening path. Look for potential obstacles, frequently used routes or immediately adjacent outdoor areas. These conditions can affect whether the window can be operated conveniently in its intended position day to day.

Document the inside and outside as clearly as possible. Notes or suitable photographs can show where junctions, wall build-ups and existing elements are located. Reliable dimensions should not, however, be derived from images alone. Measured information and visual documentation serve different purposes and merely complement one another.

The dimensions of the outer frame, sash frame and installation holes relate to those components and do not automatically define the order size of the complete window. A made-to-measure window therefore requires the dimensions and particular features of the real opening. Clarify any uncertainty about measuring, junctions or installation before ordering, and keep open points separate from confirmed measurements. This keeps building information traceable and allows it to be connected clearly with your design choices.

Colour, timber and visual composition

The visual effect of this window comes from several connected choices. First, the single sash establishes the basic composition. The selected glazing-bar layout then structures the glass area, while timber species and colour determine how the frame sits in its surroundings. None of these choices needs to be viewed in isolation. A harmonious result is more likely when the façade, neighbouring windows, doors and visible interior surfaces are considered together.

For timber species, you can choose pine or oak. Pine and oak have distinct natural appearances. As timber is a grown material, its grain and visible texture should not be regarded as a perfectly uniform printed surface. If timber elements already exist in your building, comparing their appearance can help with selection. This does not, however, promise an exact match with existing surfaces.

The window colour can be selected to suit your project. Make your enquiry as clear as possible by stating an established colour reference or the desired colour direction. Consider the façade, adjacent elements and the effect inside the room. When coordinating with existing surfaces, suitable references are more helpful than broad requests such as “to match the existing finish”.

The glazing-bar layout affects the rhythm and visual weighting of the glass area. A horizontal division can echo existing horizontal façade lines, while a vertical division emphasises other proportions. Combined patterns create a denser grid. These are general design effects, not guarantees of changed room dimensions or light levels.

The handle choice also contributes to visual coordination, as it is an operating element seen regularly. Treat it as a separate choice and describe your aesthetic and practical preferences. For a coherent overall composition, consider timber species, colour, glazing-bar layout, glazing construction and handle together. The black rubber seals belong to the glazing construction and are not a separately selectable colour feature.

Explore related window and door types

If a single sash does not suit the planned window opening or façade layout, it is worth comparing a historic double-sash outward-opening casement window. It is also available in pine or oak and can be designed with different glazing-bar layouts. The key selection difference is the composition of two sashes rather than one.

The two combination casement windows pair a fixed glazed pane with an outward-opening sash. A regular and a historic version are available. The historic combination window is offered in pine and oak; the regular combination window also has aluminium-clad options. Both product types have their own glazing-bar layouts and are useful comparisons where a fixed pane and opening sash are wanted together.

Other installation situations can be served by a roof pivot window and single- or double-sash reversible windows with a vertical pivot axis. The roof pivot window is made from pine with aluminium cladding and has a bottom-mounted operating handle. The reversible windows open outwards, are available in pine or oak, and can each also be selected with aluminium cladding. Compare these operating styles specifically with this window’s classic casement sash.

Where a low-level opening to a patio is planned, single-sash outward-opening patio doors are related product types to consider. The historic version is available in pine or oak, while the regular patio door also offers aluminium-clad options. Depending on the design, glazed versions, glazing-bar arrangements and panelled versions are available.

First identify the basic composition your project requires: one or two sashes, a fixed pane combined with a sash, a roof window, a reversible design or a patio door. Then compare materials, glazing and the available design patterns. The suitable related products are shown directly below.

Prepare your enquiry in a few steps

Start by identifying the product clearly. Note that you are enquiring about the “Historic single-sash outward-opening casement window”. This makes clear that you require the single historic casement sash, not a double-sash, combination or differently named window type.

Next, bring together the building information. Provide carefully measured dimensions of the intended opening and add notes about wall construction, junctions and notable irregularities. Keep measured values separate from estimates. If information remains unresolved, mark it as an open point rather than replacing it with an apparently precise assumption.

Then choose pine or oak and add your colour preference. Where possible, state a clear colour reference or well-described colour direction. If the window is to coordinate with existing windows, doors or façade elements, appropriate reference details or photographs can illustrate the intended effect.

Next, specify double- or triple-glazed insulated glass and the desired glazing-bar layout. Use one of the listed layout descriptions where possible so the number and direction of bars are clear. Add your handle preference as a separate selection point. SPILKA and IPA fitting details are part of the technical equipment and do not need to be stated as a choice between two brands.

Finally, check whether your project requires specific technical values or documents, and list these as clear questions. The window is CE marked and carries a five-year guarantee. A well-organised enquiry includes the product name, opening dimensions and characteristics, timber species, colour, glazing, glazing-bar layout, handle preference and any outstanding project requirements. This allows us to capture your requirements for the made-to-measure window clearly and discuss them with you in a structured way.

Is the window made to measure?

Yes. The window is offered made to measure. For a meaningful enquiry, we need the dimensions of the intended opening and information about the installation situation. Made-to-measure production does not replace professional assessment of whether the building conditions at the specific property are suitable.

Which timber species are available?

You can choose between pine and oak. Each timber species gives the window its own natural character. You can assess which version suits your project aesthetically alongside the colour, glazing-bar layout and existing building elements.

Can I choose the window colour?

Yes, colour is one of the selectable features. Tell us your preferred colour direction or an already established colour reference. For a balanced choice, consider the façade, neighbouring windows and doors, and the desired effect within the room.

Which glazing options are available?

You can select double- or triple-glazed insulated glass. Both constructions include a heat-reflective coating, a CHR warm-edge spacer and argon gas. The glazing suitable for your project should be decided against its specific requirements.

Is the window available with glazing bars?

Yes. Alongside the version without glazing bars, the layouts listed in the design-pattern section are available with horizontal and vertical bars. This allows you to coordinate the division specifically with the façade, room effect and neighbouring windows.

Is there a choice of window handle?

Yes, handle selection is one of the available purchase choices. Tell us your aesthetic and practical requirements for the handle so we can consider them in your enquiry alongside timber species, colour, glazing and glazing-bar layout.

Is the window CE marked?

Yes, the window is CE marked. If your building project also requires specific technical values or documents, please list these as separate points in your enquiry.

How long is the window guarantee?

This single-sash casement window carries a five-year guarantee. It is also CE marked.
