01

Operation and everyday use

This window combines two side-hung sashes in one unit, designed to open outwards. The movement therefore leads away from the inside face of the window. This can be particularly practical where you want to keep the indoor area directly in front of the window clear. Even so, it is worth considering operation in relation to the specific room rather than in isolation. Height, handle position, frequency of use and nearby furnishings can all affect how natural the window feels to use.

The handle choice lets you include the visible operating element in the design. A handle is both a touchpoint and a visual accent: it can sit quietly within the overall look or create a deliberate contrast. SPILKA or IPA fittings are specified for the technical equipment; handle selection should be treated as a separate design decision. If a particular shape, feel or visual effect matters to you, describe this as specifically as possible in your enquiry.

For comfortable everyday use, also consider who will primarily operate the window and when it will be opened. In a frequently used room, easy reach and an intuitive handle design may take priority. In a room entered less often, visual integration may matter more. These considerations do not alter the technical window type, but they help align the available purchasing choices with daily life.

As with every moving building component, careful use supports long-term performance. Operate the sashes and handle without unnecessary force, and arrange professional assessment if the movement changes. Cleaning and care should suit the chosen timber or timber-aluminium version. Match specific care products or maintenance work to the actual surface and installation situation rather than relying on general assumptions.

02

Construction, component dimensions and technical details

The window is designed as a two-sash outward-opening side-hung type. Available material options are pine, aluminium-clad pine, oak and aluminium-clad oak. The installation holes have a diameter of 14 mm. This dimension describes the intended holes as a construction detail and should be considered with the building fabric and chosen junction during professional installation planning.

The outer frame is specified as 105 x 57 mm. With aluminium cladding, the outer-frame component dimension is 115 x 57 mm. The sash frame is specified as 76 x 65 mm; with aluminium cladding, its component dimension is 86 x 65 mm. These figures are dimensions of the named frame components. They are not general depth, width or height measurements for the complete window, and do not replace the order size or assessment of the intended opening.

Choose from 2- or 3-pane insulating glass. Both configurations have a heat-reflective coating, a CHR warm edge and argon-gas fill. The glazing seals are black rubber. Allow for this dark detail in colour and material planning, without assuming that a black edge will be equally visible from every viewpoint.

The window is CE marked and offered with a 5-year manufacturer guarantee. For your project records, it is advisable to document the selected material version, exact dimensions, glazing configuration, muntin pattern, colour and handle together. This keeps the technical details clearly separate from individual design choices.

Assessing the intended opening properly

A made-to-measure window begins with a carefully assessed opening. Do not take only one measurement; check the building situation at several points. Existing openings can be uneven, and visible surfaces do not necessarily show the actual junction area. Order dimensions should therefore result from a suitable professional measuring method. Photos and a sketch usefully supplement measurements, but do not replace reliable site measurement.

Because the sashes open outwards, the required opening and movement space outside is a key planning point. Check whether reveals, railings, external shading, plants, fittings on other components or other obstacles could enter the movement area. Future access for operating, maintaining and cleaning should also suit the installation position. This assessment concerns the actual site and cannot be answered from the product name alone.

Inside, the window sill, wall linings and handle position can be relevant for comfortable use even though the sash movement itself is outward. Also consider how the frame will connect to adjacent materials. Masonry, timber construction, cladding and remnants of existing frames may require different planning solutions. The product is made to measure, but custom manufacture does not replace the need for a suitable installation and junction concept.

If the window is part of a row or divided façade, also record reference heights and visible lines. Muntins, frame edges and neighbouring openings can only be deliberately coordinated when their positions are known. For a replacement project, overall views are often as useful as close-up photographs. For a new build, drawings can show the intended relationship.

If any part of the situation is uncertain, have a suitably qualified person check the measuring and building fabric. Then send us the reliable dimensions and key conditions. The more clearly the opening, junction and possible obstacles are described, the more specifically material, glazing and design decisions can be related to the project.

Material, colour and visual composition

The window is available in pine or oak, with either timber species also offered with aluminium cladding. This provides different material expressions for the design. Timber influences perception through its natural character, while aluminium cladding adds another surface to the external appearance. Which version suits the project depends on the intended relationship between interior, façade and adjacent building elements.

The available colour choice extends this design scope. Colour can visually blend a window into a wall surface, match it to other elements or make it stand out deliberately. Do not judge only a small colour sample on its own. Compare the intended effect with the roof, façade, doors, visible metalwork and the colour temperature inside. Existing timber surfaces can also provide an important reference.

The muntin pattern, frame material and colour should be considered as one composition. A strongly divided glazed area can be integrated quietly with a restrained colour, while a contrasting colour can make a simple muntin-free design stand out. These are design possibilities, not guaranteed results. Light, surroundings and viewing distance change how proportions and colour transitions are perceived.

The handle is also part of the visible overall design. Its form and appearance can relate to other handles or fittings in the building. In your enquiry, describe whether you prefer subtle integration or a deliberate design accent.

If you are weighing pine against oak, or all-timber against a clad version, make a short list of priorities. Should the timber species set the tone inside? Is a particular material relationship wanted outside? Must several windows match visually? Answers to these questions help make the selection clear. We can then consider your information as an overall brief rather than treating colour, material, muntins and handle separately.

Comparing related product types purposefully

For a useful product comparison, first decide what role the particular opening should perform in the building. Important differences include the number of sashes, opening direction, movement type and whether a fixed glazed panel should form part of the composition. Installation position also matters: a façade window, roof window and patio door perform different tasks. Compare the product type first, then the materials, glazing and design options.

The two outward-opening combination side-hung windows combine a fixed glazed panel with one sash. Both are available in pine or oak and with 2- or 3-pane insulating glass. In the regular combination version, both timber species can also be selected with aluminium cladding, while the traditional-style version is offered in pine or oak. Different muntin patterns allow the fixed panel and sash to be coordinated in both versions.

For the roof, a centre-pivot roof window in aluminium-clad pine is available. It has a bottom-mounted operating handle and 2-pane insulating glazing with heat-reflective coating and argon-gas fill. The single- and two-sash reversible windows with a vertical pivot, by contrast, open outwards and are available in pine or oak, each also with aluminium cladding. The single-sash inward-opening window adds a tilt function and uses Roto Frank fittings.

For direct access outside, compare the single-sash outward-opening patio doors. Both variants have SPILKA and ASSA fittings with 3-point locking and, depending on the version, are available with glazing and a panel. The regular patio door is offered in pine or oak, each also with aluminium cladding. The traditional-style patio door is available in pine or oak. Different muntin and panel patterns are also available for design coordination.

Use a fixed order when comparing: first clarify installation position, product type and opening direction. Then check whether you need one or two sashes, a fixed glazed panel, a tilt function or a doorway. You can then compare the materials, glazing and muntin patterns offered for each. This keeps the choice focused not only on appearance, but also on intended use and building context.

Prepare your enquiry in clear steps

Start with a short project description. State whether it is a new build, renovation or replacement of an existing window. Describe the room, façade situation and intended role of the window in the overall appearance. A brief, specific outline helps us more than a long collection of unrelated individual wishes.

Then gather reliable dimensions. Add photographs, elevations or a simple sketch showing adjoining building elements. Mark which information has already been professionally checked and which remains at planning stage. This distinguishes fixed requirements from open decisions without introducing assumptions into the brief.

Next, choose the basic material version: pine, oak or either option with aluminium cladding. Note the desired colour and what it should relate to. If several windows or doors belong together, send an overall view where possible. This makes recurring lines and material relationships easier to identify.

In the next step, determine the available glazing configuration and desired muntin pattern. For the pattern, use the complete stated design name where possible. This avoids misunderstandings over horizontal and vertical divisions. Add your handle preference separately. If only a particular visual effect is important, you can describe it without assuming a specific handle version.

Finally, check whether all choices appear compatible: does the division suit the façade? Has the material effect inside and outside been considered? Are colour and handle intended as parts of the same composition? Have particular building conditions been stated? A final order of priorities is useful if individual preferences still need discussion. Tell us which points are essential and where you are open to joint consideration. With this structured basis, we can record your enquiry efficiently and focus on any details still to be clarified.

Can the window be ordered made to measure?

Yes. The window is offered made to measure. Dimensions of the intended opening and information about the installation situation are helpful for an enquiry. If in doubt, arrange a professional site assessment so that order dimensions suit the actual building fabric and planned junction.

Can I choose a colour?

Yes, colour selection is one of the available purchasing choices. Consider the timber species, any desired aluminium cladding, façade, interior and existing building elements. Tell us as specifically as possible what design effect you want to achieve inside and outside.

Can I choose the window handle?

Yes, a handle choice is available. It concerns the visible operating element and should suit both the intended design and everyday handling. The named fitting brands, by contrast, are technical product details and do not constitute a separately guaranteed choice between manufacturers.

How long is the window guarantee?

The window has a 5-year manufacturer guarantee. Keep the selected version, dimensions, material, glazing, muntin pattern, colour and handle in your order records, and retain the related documentation.

What is the role of aluminium cladding?

Aluminium cladding is specified as an option for pine and oak. It changes the external material expression and the dimensions of the affected frame components. You can assess which version suits your project from the façade, colour concept and desired material transitions.

How do I choose a suitable muntin pattern?

Choose the muntin pattern according to the desired division, proportions and relationship to the architecture. A calm façade may benefit from a restrained arrangement, while more strongly divided existing elevations may suggest a more detailed pattern. The overall effect matters, not only the window viewed alone.

What should I consider when cleaning?

Because the sashes move outwards, future cleaning should be considered during planning. Check where the external surfaces can be reached from, taking account of storey height and surroundings. For difficult-to-access installations, a coordinated cleaning and access plan is advisable.

What details help with a specific enquiry?

Useful information includes opening dimensions, photographs, sketches and a short project description. Add your preferences for timber species, aluminium cladding, colour, handle, glazing and muntin pattern. Also note adjoining elements or design requirements that should be considered in the selection.
