01

Operation and everyday use

This window has one side-hung sash that opens to the outside rather than swinging into the room. Its open sash therefore leaves the internal space immediately in front of the window unaffected by its movement. That may be useful when considering room use, although it is not a statement that any particular furniture or window treatment will suit. The installed position and everyday use at your property determine this.

For comfortable everyday operation, consider early where you will stand to use the sash. The handle is selectable, so it can be chosen for practical access as well as the window’s appearance. Please state your handle preference in the enquiry. SPILKA and IPA are specified fittings; they form part of the technical equipment rather than a separately listed purchase choice.

How often the window is opened and how easily the handle should be reached depend on the room and your routines. Check whether furniture, deep internal reveals or window furnishings could restrict access to the control. Outside, allow adequate clear space for the sash to swing open. This brings both interior layout and site conditions into planning before ordering.

Clean and maintain timber, glass and rubber seals as different materials. Select products and tools suited to each surface, avoiding harsh cleaners and abrasive implements. Guide the sash steadily while opening and closing, and operate the handle without excessive force. Also follow the care instructions for the selected timber and paint finish.

02

Construction and component dimensions

The window comprises an outer frame and one sash frame. The outer frame is the fixed element installed in the opening, while the sash frame holds the moving sash. Their dimensions, plus the installation-hole size, are listed in the fact summary. These figures refer specifically to the named components; they are not general depth, width or height measurements for the complete window.

Pine and oak are available for the timber construction. The choice affects more than the material name: each timber gives the window its natural character. Timber has its own grain and visible variation, which are inherent qualities of the material. Consider these natural differences when coordinating with existing timber elements. A colour choice is also available, so timber species and the intended colour effect can be considered together.

The outer frame, sash frame, glazing, seals and fittings work together as the window’s construction. SPILKA and IPA are specified for the fittings. Timber species, colour and handle are instead details you select with your enquiry. Keeping this distinction clear helps separate technical product information from individual design preferences.

For a custom window, component dimensions must be distinguished from the overall size. Profile measurements explain the construction of the frame parts, while the finished window size is matched to the intended opening. Do not plan installation from individual profile figures alone. A complete sizing assessment needs information about the actual opening and building conditions.

The window is CE marked and offered with a five-year warranty. Treat these details separately from project-specific requirements. If your project needs particular performance values or documents, include them as specific questions in your enquiry so the suitable version can be checked against the building’s requirements.

05

Assessing the intended window opening

Assess the actual opening carefully before making an enquiry. Because the sash opens outwards, the clear opening size is not the only relevant consideration. The area outside must also be included in planning. Reveals, external sills, railings, planting, fittings on other elements or structural projections may affect the situation. Whether any of these obstructs the window must be checked from the real arrangement.

Record the opening at several suitable positions and note any visible variation. In older buildings, edges, reveals and connections can be irregular, so one quickly taken figure may not represent the site adequately. Also state whether this is an existing opening, a planned new-build connection or a replacement window. That information helps put the measurements in context.

Then check the movement area for the outward-opening sash. What matters is the space actually available through its opening arc. Look for possible obstacles, frequently used paths and immediately adjacent outdoor areas. These conditions can affect whether the window can be operated sensibly in daily use at the proposed location.

Document the internal and external sides as clearly as possible. Notes or suitable images can show the position of connections, wall build-ups and existing elements. Reliable dimensions should not, however, be derived from photographs alone. Measurements and visual records have different purposes and only complement one another.

The dimensions stated for the outer frame, sash frame and installation holes describe those parts only and do not automatically determine the complete window’s order size. A custom-made window needs the measurements and site-specific features of the actual opening. Check any uncertainty about measuring, connections or installation before ordering, and distinguish unresolved matters from verified figures. This makes the building information clear and allows it to be coordinated with the selected design.

Colour, timber and visual composition

The visual character of this window comes from several connected decisions. The single sash establishes the basic composition, the chosen glazing-bar pattern structures the glass, and timber species and colour determine how the frame sits within its surroundings. These choices need not be considered in isolation. A coherent result is more likely when the façade, nearby windows, doors and visible internal surfaces are assessed together.

Choose between pine and oak. Each has a different natural appearance. As timber is a grown material, grain and visible structure should not be expected to be as uniform as a printed surface. Where the building already includes timber components, comparing their character can help with selection. This does not promise an exact match with existing surfaces.

Select the window colour to suit your project. Make the enquiry as clear as possible by providing an established colour reference or describing the desired colour direction. Consider the façade, adjacent elements and the intended effect inside the room. When matching existing surfaces, suitable references are more useful than broad descriptions such as “to match existing”.

Glazing bars shape the balance of the glass. They can echo horizontal features on the façade, emphasise different proportions through vertical lines or, in combined layouts, form tighter grids. These effects are aesthetic, not guaranteed changes in light or room dimensions.

Handle selection also contributes to the visual coordination, as the handle is a regularly seen operating element. Treat it as its own choice and describe both practical and design preferences. For a considered overall composition, view timber species, colour, glazing-bar pattern, 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 one sash does not suit the intended opening or façade arrangement, compare a historic-style double-sash side-hung window. It also opens outwards, is offered in pine or oak, and can be designed with different glazing-bar patterns. The key difference is the composition of two sashes rather than one.

The two combination side-hung windows pair a fixed glazed section 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 provide a comparison where a fixed field and opening sash are required.

Other settings may call for a roof pivot window or single- and double-sash reversible windows with a vertical pivot axis. The roof model is pine with aluminium cladding and a bottom-mounted handle. The reversible windows open outwards, come in pine or oak, and can also have aluminium cladding. Compare each operating method directly with this window’s conventional side-hung sash design.

For a low-level opening leading to a terrace, related product types include the single-sash outward-opening terrace doors. The historic version is available in pine or oak, while the regular terrace door also offers aluminium-clad versions. Depending on the design, glazed versions, glazing-bar arrangements and panel versions are available.

First establish the basic format your project needs: one or two sashes, a fixed field with sash, a roof window, a reversible design or a terrace door. Then compare materials, glazing and the available design patterns. You will find the suitable related products directly below.

Prepare your enquiry in a few steps

Begin by identifying the product clearly. State that you are enquiring about the “Historic-style single-sash outward-opening side-hung window”. This confirms that the request concerns the individual historic sash, not a double-sash, combination or differently named window type.

Next, bring together the building details. Provide carefully taken measurements of the intended opening and add notes about wall construction, connections and noticeable irregularities. Keep measured values separate from estimates. If something is unresolved, mark it as an open point instead of substituting an apparently precise assumption.

Then select pine or oak and add your colour preference. Where possible, provide a clear colour reference or a well-described colour direction. If the window is to coordinate with existing windows, doors or façade elements, useful references or images can illustrate the intended result.

After that, nominate the double- or triple-glazed insulated unit and your preferred glazing-bar pattern. Use one of the listed descriptions for the divisions where possible, so their number and direction are clear. Add the desired handle as a separate choice. SPILKA and IPA are technical fittings and do not need to be presented as a choice between brands.

Finally, check whether the project needs particular technical values or documents, and list these as specific questions. The window is CE marked and carries a five-year warranty. A well-organised enquiry includes the product name, opening dimensions and features, timber, colour, glazing, bar pattern, handle preference and any unresolved project requirements. This allows us to record your requirements for the custom outward-opening side-hung window clearly and discuss them in a structured way.

Is the window made to measure?

Yes. The window is made to measure. For a clear enquiry, provide dimensions of the intended opening and installation details. Custom manufacture does not replace professional assessment of whether conditions at the specific building are suitable.

Which timber species are available?

You can choose pine or oak. Each timber gives the window its own natural character. Assess which version suits your project visually alongside colour, glazing-bar pattern and the building elements already present.

Can I choose the window colour?

Yes, colour is one of the selectable features. Tell us your preferred colour direction or an established colour reference. For a harmonious choice, consider the façade, neighbouring windows and doors, and the effect you want inside the room.

Which glazing options are available?

Choose a double- or triple-glazed insulated unit. Both constructions have a heat-reflective coating, a CHR warm-edge spacer and argon gas. The appropriate glazing should be decided according to the requirements of the individual project.

Is the window available with glazing bars?

Yes. The window can be supplied without glazing bars or in the horizontal and vertical arrangements described in the design-pattern section. You can therefore select divisions that work with the façade, the desired room appearance and nearby windows.

Is there a choice of window handle?

Yes, a handle choice is among the available purchase decisions. Tell us your design and practical preferences for the handle so they can be considered with timber species, colour, glazing and glazing-bar pattern in your enquiry.

Is the window CE marked?

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

How long is the window warranty?

The single-sash side-hung window has a five-year warranty. It is also CE marked.
