01

Opening, closing and everyday use

The window is a two-sash construction with outward-opening casement sashes. When operated, the sashes move away from the interior. This can suit situations where the indoor area near the window should remain as clear as possible of inward-swinging sashes. However, the defined opening type should always be considered alongside the installation location and your everyday routines.

For daily use, operate the selected handle calmly and with control. Open and close the window while guiding the sash rather than allowing it to move uncontrolled. As with any timber window, careful use helps you keep an eye on surfaces, glass, seals and hardware. Remove visible dirt with suitable gentle products, avoiding aggressive or abrasive cleaning methods.

The handle choice is an orderable design feature. It affects the direct contact point during operation and forms part of the room-side appearance. State your preferred handle style together with the timber, colour and glazing-bar pattern. This design decision differs from the fitted hardware components: SPILKA and IPA identify the specified hardware, not freely selectable brand alternatives.

When choosing the window, consider how often it is likely to be operated and who will use it daily. These considerations do not alter the defined opening type, but help incorporate the handle into your use plan. After installation, check regularly that the window operates as intended and that seals or hardware areas show no visible dirt. If it behaves unusually, investigate the cause instead of forcing the sash.

With a two-sash arrangement, the operating sequence also matters in daily use. Ask for guidance on opening and closing the two sashes in your chosen configuration. Everyone using the window can then follow the intended procedure and operate the sashes in a controlled way.

02

Construction, component dimensions and technical details

The outer frame is specified at 105 × 57 mm and the sash frame at 76 × 65 mm. These component dimensions differ from the made-to-measure dimensions of the finished window. For your enquiry, provide carefully measured project dimensions and identify every value clearly on a labelled sketch.

Installation holes are specified at 14 mm. The installation situation should be assessed as a whole, as masonry, junctions and adjacent components must be included in planning. The specified hardware components are from SPILKA and IPA. These brand names describe the intended equipment; they are not a choice of hardware brands when ordering.

The window is available with 2- or 3-pane insulating glass. Both glazing constructions include a heat-reflective coating, a warm-edge spacer designated CHR and argon gas fill. The glazing seals are black rubber. For your configuration, state whether you require the 2- or 3-pane version.

The window is CE-marked and offered with a 5-year guarantee. These details form part of the defined product specification. For project records, keep the product name and selected features together so technical information is not inadvertently confused with that of a similarly named window type.

Pine and oak are available as frame materials. You can also select made-to-measure manufacture, colour and handle style. The technical details form the shared product basis, while these orderable features determine your individual configuration. This keeps fixed construction properties clearly separate from personal design choices.

05

Assessing the intended opening carefully

Because the casement sashes open outwards, the proposed window opening should be assessed spatially as well as measured. Look at the area directly in front of the window and consider where the sashes would move when opened. Relevant features may include a deep external sill, façade projections, railings, downpipes, shutters, planting or other permanently fitted elements.

Also consider outdoor areas used regularly. If the opening faces a patio, narrow path or an area where items are stored, sash movement may matter in everyday use. Assess the particular location realistically, including both fixed features and the normal use of the outside area.

Measurements must reflect the actual building situation. Measure the opening at several suitable points and document visible deviations instead of assuming it is perfectly square or uniform. Clearly distinguish structural-opening dimensions from the required window dimensions. The stated outer-frame and sash-frame dimensions do not replace project-specific measurement.

Consider adjoining surfaces and junctions too. Render edges, cladding, window sills and construction transitions may be relevant to positioning the window. When replacing an existing window, its visible outside dimensions may not be enough to describe the whole opening. A clear sketch with unambiguous dimension references can prevent misunderstandings in the enquiry.

Photographs of the opening can be useful additions, but do not replace accurate dimensions. Note from which side each view was taken and which adjoining components are visible. Check the area under realistic conditions and allow for changes caused by movable or seasonal elements. This treats the outward sash movement as part of the installation situation from the outset.

06

Bringing timber, colour and lines together

The visual effect comes from the interplay of the two-sash form, timber species, colour, handle and glazing-bar pattern. Pine and oak are available materials. Both can be incorporated into a historic design concept, but should not be considered separately from the building’s existing timber elements, surfaces and colours.

Colour selection is part of the orderable configuration. It allows the window to complement an existing façade concept or stand out as a deliberate feature. Consider larger surfaces such as render or timber cladding as well as smaller details on doors, eaves or other windows. A colour can appear different depending on surrounding materials and light conditions.

The glazing-bar pattern sets the rhythm within the sashes. Horizontal lines can relate to façade bands or neighbouring window divisions. Vertical lines can support an upright arrangement. Combined grids appear more subdivided, while the bar-free view remains calmer. The key is to choose one named design and state its title in full.

The handle also belongs to the visible composition on the room side. As a handle choice is available, decide on it together with the colour, timber and glazing-bar pattern. The SPILKA and IPA hardware brands are separate: they identify fitted hardware components, not a choice between manufacturers.

For a coherent result, it can help to create a small material and colour overview for the project. Note the chosen timber, desired colour, handle style and full name of the glazing-bar pattern. Add notes about neighbouring components if their design should be reflected. This lets you view individual decisions as a coordinated window composition and communicate your requirements clearly.

Comparing related window types and patio doors

Alongside this two-sash casement window, our range includes other windows and patio doors for different installation situations. First compare product type and opening direction. Then check whether you need two moving sashes, a fixed-light-and-sash combination, a roof window or a patio door. Afterwards, compare materials, glazing and design options within the appropriate product group.

The “Historic outward-opening ‘Kombi’ casement window” combines a fixed glazed light with one sash and offers several glazing-bar patterns. The “Roof pivot window”, by contrast, belongs to the roof-window product group and is operated as a pivot window with a handle at the bottom. Both types therefore have a different basic construction from the two-sash casement window shown here.

For windows with a vertical pivot axis, single- and two-sash reversible windows are available for comparison; both open outwards. If sashes should open into the room, compare the single- or two-sash inward-opening windows instead. Pay particular attention to the differing opening and tilt functions, and to the materials and glazing-bar patterns listed for each.

For ground-level access outside, you can also consider single-sash outward-opening patio doors. Alongside the general version, a historic-style option is available. Both product groups offer glazed designs and, depending on the design, versions with solid panels. Compare the door design, material selection, glazing and locking with your project requirements.

Start your comparison with the intended use: standard window, roof window or patio door. Then decide on opening direction, number of sashes and any combination with a fixed light. Finally compare timber species, aluminium cladding, glazing and the available glazing-bar patterns.

Prepare your enquiry in clear steps

Start with a clear project description. Use the full name “Historic outward-opening two-sash casement window” so the required product is not confused with a reversible window, inward-opening window or patio door. You can also note the room or façade side where the window is intended, where this helps identify it within your project.

Then add carefully taken dimensions. A labelled sketch can show which value relates to which point. Identify special features of the existing opening and distinguish between the structural opening and the desired finished dimension. If you are enquiring about several windows, give every position its own consistent reference so details are not mixed up.

Next, define the design features. State pine or oak, describe the desired colour and specify your handle selection. Use the exact provided design name for the glazing-bar pattern. This makes clear whether you want a bar-free, horizontally divided, vertically divided or combined appearance.

Add your choice of 2- or 3-pane insulating glass. Keep this detail in the same overview as the other product features. Images of existing windows or façade details can clarify your design reference; label which feature is intended as guidance, such as the line arrangement or colour direction.

Finally, check every detail for consistency and completeness. The product name, dimensions, timber species, colour, handle, glazing and complete design name should all be assigned clearly. Gather any additional questions in a separate section. This concise sequence creates an understandable basis for discussing your enquiry in a focused way.

Is the window available made to measure?

Yes. The window is available made to measure. For a clear enquiry, carefully measure the intended opening and also state the required timber, colour, glazing, handle style and glazing-bar design.

Which timber species can I choose?

Pine and oak are available. Both form part of the defined product specification. Assess which timber suits your project best by considering the desired room effect, existing components and your design concept.

Can I choose the window colour?

Yes. Colour selection is one of the orderable features. It lets you coordinate the timber window with a historic façade, existing timber components or a deliberately individual colour concept. State the specific colour in your enquiry.

Is there a choice of handles?

Yes. The handle style can be selected as part of the configuration. State your preferred option with the other design features. The named hardware brands, by contrast, identify fitted components and are not freely selectable brand alternatives.

How long is the window guarantee valid?

The two-sash casement window comes with a five-year guarantee. Keep the exact product name and your selected configuration in your project records so the information can later be assigned clearly to the window.

Must the window be ordered with glazing bars?

No. You can choose a version without glazing bars. Several named glazing-bar patterns with horizontal and vertical lines are also available. This lets you create a division that suits the desired historic façade arrangement.

What should I consider about the outward opening?

Check the opening direction at the actual installation location. Consider adjacent components, window sills, railings, planting, drainage elements and outdoor areas used regularly. Seasonal changes in the immediate surroundings should also be included in the assessment.

Which glazing is available for the window?

Choose between 2- and 3-pane insulating glass. Both versions have a heat-reflective coating, a warm-edge spacer designated CHR and argon gas fill. State the required glazing construction clearly in your enquiry.
