01

Operation and everyday use

With this window type, the single sash swings outwards when opened. Its basic direction of movement is therefore clear and can be considered at an early planning stage. In daily use, allow consciously for the outward movement. Open and close the sash in a controlled way using the handle, guiding it evenly rather than moving it with force. A calm, careful action helps protect the window, hardware and seals.

Because the sash swings outwards, its movement area should remain clear. This matters especially where planters, decorations or other movable items are placed directly in front of the window. Also consider nearby sills, cladding and projecting building elements. When ventilating, closing or cleaning, keep the direction of movement in mind and guide the sash carefully.

The handle is one of the selectable parts of your order and is used regularly every day. Coordinate its style with the frame material, colour and glazing-bar pattern, and include your handle preference in the configuration overview. SPILKA and IPA hardware is specified for the window construction. Handle, hardware and sash work as one functional unit and should be considered together when specifying the window.

Before closing, check that the sash can return to the frame without objects in the way. Remove obstructions from its movement area and operate the handle without unnecessary force. Keep accessible frame and sash areas free from coarse dirt. Everyday use then remains straightforward: operate the handle, guide the sash steadily and keep its immediate movement area clear.

02

Construction, components and technical dimensions

The window comprises an outer frame and a single sash frame. The stated dimensions refer specifically to these components and are not the overall dimensions of the complete window. The outer frame has a cross-section of 105 × 57 mm. With aluminium cladding, the outer frame measures 115 × 57 mm. The sash frame is stated as 76 × 65 mm; with aluminium cladding it is 86 × 65 mm. Installation holes are specified as 14 mm. These values identify individual components and must not be interpreted as the depth, width or height of the ordered window.

Choose either a double- or triple-glazed insulating glass unit. The product is CE marked and carries a 5-year warranty. SPILKA and IPA are specified as the hardware. They form part of the window construction, while your enquiry can also define the preferred handle design. Record the handle together with the material, colour, glazing and glazing-bar pattern as part of your configuration.

You can choose pine or oak timber. Both wood types are also available with aluminium cladding. This means all-timber versions and versions with aluminium cladding are available. Aluminium cladding also changes the stated component dimensions, so it should be clearly noted in your enquiry from the outset.

When sharing technical details for planning or coordination, use the component names alongside their corresponding values. This makes clear whether the outer frame, sash frame or installation holes are being discussed. Final window dimensions are not obtained by simply adding cross-section values; they must be set for the requested custom-made window and the intended opening.

05

Assessing the intended opening carefully

A custom-made window starts with a clear description of the intended opening. Do not record only one measurement; check the situation at several points. Structural openings may vary in ways that are not immediately visible. Note where measurements were taken and record any features of the reveals, junctions and adjacent surfaces. Measured opening dimensions must be distinguished from the component cross-sections stated in the construction section.

When assessing the opening, remember that the sash moves outwards. The clear space needed depends on the particular window version and installation situation and should be considered for the project. External elements, parapets, railings, cladding, sills or permanently placed objects may be relevant. Roof overhangs and other projecting features also deserve attention if they are close to the movement area.

Also check how the frame is intended to connect to surrounding building elements. The installation situation may affect which details are needed for your enquiry. An internal view, external view and simple section sketch can help make the description clear. Photos are useful when they show the opening unobstructed and indicate scale, but they do not replace carefully recorded measurements.

If you are unsure, identify open points clearly rather than entering assumptions as fixed requirements. Keep existing opening dimensions, desired overall window dimensions and known junction requirements separate. This helps prevent a component dimension from being used mistakenly as an order dimension. A well-structured site record creates a sound basis for discussion without pre-empting a project-specific assessment.

Material, colour and visual composition

Pine and oak give you two different timber bases for the design. Both are available with or without aluminium cladding. Decide on this fundamental material specification before coordinating the colour, handle and glazing-bar pattern. The individual design decisions can then be brought together in one clearly described final version.

A choice of colours is available. This allows the window to relate to the façade surface, adjoining elements or the interior scheme. A quiet, similar shade can integrate the window more closely with its setting; a deliberate contrast can highlight its outline or glazing-bar pattern. Such effects depend on the project, light and surrounding materials and are not fixed product properties.

Never consider colour entirely apart from the material. Timber surfaces and aluminium-clad areas can be perceived differently, even when they form part of a coordinated concept. The handle also contributes to the overall appearance. It can be selected to sit quietly with the frame or treated as a deliberate detail. Record the specific handle choice with the colour in your enquiry.

The glazing-bar pattern forms the graphic layer of the composition. A version without bars looks different from one with horizontal, vertical or crossing lines. Where a coordinated appearance is wanted, align this layout with neighbouring windows and doors where possible. Include timber type, aluminium cladding, window colour and handle in this assessment. Existing material or colour samples and a façade sketch can assist comparison, while light, surroundings and viewing distance all influence the final overall impression.

07

Understanding related product types

For projects with different openings, it is useful to compare related product types. A double-sash version has a different sash arrangement from this single-sash side-hung window, while both categories are available as outward-opening designs. The standard double-sash version is available in pine or oak, each also with aluminium cladding. The heritage-style double-sash version is specified in pine and oak. Both product types are available with double- or triple-glazed insulating glass units and different glazing-bar patterns.

Combination versions pair a fixed glazed section with a sash. Several designs without glazing bars and with horizontal and vertical bars are specified. The standard combination version is available in pine or oak, each also with aluminium cladding. Heritage-style products are available in pine and oak, but not with aluminium cladding. These material differences matter especially where several windows on one façade are intended to share a common surface concept.

Separate window categories are also available for other installation areas. The roof pivot window is described with a bottom-mounted operating handle, pine with aluminium cladding and double-glazed insulating glass. The single-sash reversible window has a vertical pivot axis and opens outwards; it is available in pine or oak, with or without aluminium cladding, and with a double- or triple-glazed insulating glass unit. Compare opening type, material and glazing as well as appearance.

Single-sash patio doors form another related product group. They also open outwards and are available with 2-pane or 3-pane insulating glass; depending on the version, a panel may be included. The standard version is available in pine and oak and with aluminium cladding, while the heritage-style version is limited to pine or oak. SPILKA and ASSA hardware with 3-point locking is specified. The product links below take you to the respective versions and their available designs.

Prepare your enquiry in a few steps

Start with the product identity: note that you are enquiring about a single-sash, outward-opening side-hung window. Then add the required dimensions and state clearly whether these are measurements of the existing opening or already defined overall window dimensions. A small labelled sketch can prevent misunderstandings and show from which viewing direction your information should be read.

Next, define the material. Select pine or oak and state whether aluminium cladding is required. Add your preferred colour using a clear colour description where possible. If you would like a particular handle, include it directly in the same configuration overview. This keeps material, finish and operating detail recognisable as related decisions.

Then select a glazing-bar pattern from the available designs. Use the complete designation so the number and direction of horizontal and vertical bars remain clear. Also state whether you want a double- or triple-glazed insulating glass unit. If a certain line arrangement or coordination with existing windows is particularly important, add a labelled elevation sketch. This makes the glazing-bar pattern, glazing and design aim clear at a glance.

Finally, summarise project-related notes. These may include details of the installation situation, adjacent building elements or a shared design with other windows and doors. Organise photos and drawings so each file is clearly labelled. Before sending, check that the product name, dimensions, material, cladding, colour, handle, glazing-bar pattern and glazing are included. This compact sequence supports a shared understanding and helps focus follow-up questions on decisions that remain open.

Is the window available as a custom-made product?

Yes. The window can be requested as a custom-made product. Provide carefully measured dimensions for the intended opening. Details of the installation situation are also helpful, so your enquiry can be clearly identified and discussed.

Can I choose the window colour?

Yes, a range of colours is available. Coordinate your preferred shade with the façade, interior, material and any existing components. Include the specific colour in your enquiry.

Can I choose a handle?

Yes, handle selection is one of the available configuration options. Tell us your preferred handle together with the material, colour, glazing and glazing-bar pattern. SPILKA and IPA hardware is specified for the window construction; the handle is coordinated as part of the requested overall version.

Which timber types are available with aluminium cladding?

Both pine and oak are available with aluminium cladding. Alternatively, you can choose an all-timber version. In your enquiry, therefore state clearly alongside the timber type whether the window should be supplied with or without aluminium cladding.

Which glazing is available for the side-hung window?

Double- or triple-glazed insulating glass units are available. The glazing build-up includes a heat-reflective coating, a CHR warm-edge spacer and argon filling. State the desired option with the rest of the configuration details in your enquiry.

How do I choose a glazing-bar pattern?

Choose according to how calm or structured you want the glass area to appear and which lines suit your building. A sketch of the desired look or the exact name of the glazing-bar pattern helps us understand your design intention clearly.

Which details help assess the intended opening?

Record the measured opening dimensions and add notes about junctions, reveals and adjacent building elements. Photos or a simple drawing can support the description if they show the actual situation clearly and without distortion.

Is the window CE marked and how long is the warranty?

Yes, the single-sash outward-opening side-hung window is CE marked. The product has a 5-year warranty. Keep the documents for your specific order so that the selected version and related information can be clearly traced later.
