Combination Windows

Glass areas, materials and divisions in harmonious balance

Combination windows

Our combination window is made to measure and available in a choice of colours. Pine, oak and versions of each with aluminium cladding offer distinct material effects, while five available glazing-bar patterns shape the glass view. A handle can also be selected where the chosen arrangement includes suitable opening sections.

01

Plan use and operation from the outset

With a combination window, the arrangement of individual sections shapes both the appearance and everyday use. Consider early which areas must remain accessible and what function you expect from them. Describe these requirements with your preferred layout so the visual divisions and practical use can be assessed as one connected concept.

Where the selected arrangement includes suitable opening sections, you can choose a handle. Coordinate its visible finish with the frame material, colour and glazing-bar pattern, rather than selecting it separately from the actual window configuration. Above all, your enquiry should clearly show how you intend to use the relevant sections day to day.

Also consider access to glass and frame surfaces. Furniture, worktops, deep reveals, curtains, or internal privacy and sun-control elements can affect how easily you reach the window. A room sketch can make these conditions clear and help compare the intended window composition with the real pattern of use.

Future care should also form part of the plan. Glass, timber surfaces, aluminium-clad external faces and handles need cleaning suited to their materials. Use appropriate care products and gentle tools, and follow the care instructions for the selected finish. Easy-to-reach surfaces simplify regular cleaning and help keep materials well looked after.

For a wide wall opening, you might first decide how the whole area should be visually divided. Then check which sections need to be accessible and whether the chosen layout provides suitable opening sections. This creates a window composition where design, usability and room conditions are considered together from the beginning.

02

Construction, component dimension and documented key details

The frame is available in four material finishes: pine, pine with aluminium cladding, oak, and oak with aluminium cladding. You can therefore select one of the two timber species and choose either a pure timber version or one with aluminium cladding. Consider both the interior effect and the desired external appearance when deciding.

A component dimension of 14 mm is specified for the fixing holes. This measurement refers expressly to the fixing holes. It is not the window depth, width or height, nor a general measurement for the frame, profile or installation opening. Use it only in its stated context when planning. The actual window dimensions result from the made-to-measure design and intended opening.

The insulating glass unit is offered with 2 or 3 panes. Both versions form part of the stated glazing construction and are supplemented by further defined components. The version intended for your project should be included in the enquiry and must not be inferred from the exterior appearance alone.

The combination window carries a warranty of 5 years. Keep the documents supplied with the purchase and product, and observe the conditions, care guidance and usage instructions they describe. The warranty should be distinguished from suitable planning, professional installation and project-specific suitability.

The combination window is CE marked. Individual dimensions, connections and local installation conditions nevertheless remain essential to project planning. Keep the different details separate: 14 mm applies only to the fixing holes, two or three panes to the insulating glass unit, and the five-year warranty to the product. Overall dimensions are set to suit the intended opening.

05

Assessing the intended opening carefully

As the combination window is made to measure, planning begins with a reliable assessment of the existing or proposed opening. Do not record only one overall measurement. Check the opening in several places and note whether wall faces, reveals or adjacent components are straight, level and square. Dimensions derived for ordering should be checked by a suitably qualified person.

Clearly distinguish between the structural opening, the desired overall window size and the visible glass or frame division. These details serve different purposes and must not be treated as equivalent without checking. Also document the side from which dimensions and views are considered. A clear internal and external view prevents an intended division from being interpreted as a mirror image.

Installation conditions also include the junctions around the opening. The façade, internal lining, sill, sealing layers and adjacent components can affect how the window is sized and positioned within the opening. Record these areas in your sketch and coordinate connection planning with the building and the requirements that apply at the installation location.

Include necessary clearances and operating space in the project plan. Describe in your enquiry how you intend to use the window and whether furniture, work surfaces, sloping ceilings, curtains or other elements extend close to the opening. Where the chosen arrangement includes opening sections, their accessibility and required clearance must suit the actual room conditions.

For a newly planned opening, it can help to show the future window composition in a scaled drawing. For an existing opening, clear photographs and a sketch of adjoining wall areas are also useful. Photographs do not replace dimensions, but they improve understanding of the situation. Note whether visible lines of neighbouring windows or doors should be picked up. This preparation provides a sound basis without deriving unchecked finished dimensions from a rough wall opening.

06

Material, colour and proportion as a visual composition

The material selection includes pine, pine with aluminium cladding, oak and oak with aluminium cladding. Pine and oak each bring their own natural material character to the interior. In the clad versions, the selected timber base is combined with aluminium cladding, allowing you to consider the material decision for internal and external views as one connected design choice.

Colour choice is one of the available purchasing decisions. Always consider colour alongside the selected material and the window position. A shade can appear different indoors than on the façade because light, surrounding surfaces and viewing distance vary. Record which viewing side matters most to your choice and which existing colours should serve as references.

For a more complex window area, the effect is not created by colour alone. Frame lines, glass proportions, glazing-bar direction and the proportions of individual sections all form the composition. A restrained colour relationship with adjacent components can unify the overall area. A deliberate contrast can make the divisions more pronounced. Both are design possibilities, not promised effects in every setting.

Assess the visible effect using the actual material and colour finish selected. Particularly with a larger window composition, it is worth considering internal and external views separately because light, façade materials and surrounding surfaces change perception. A clearly labelled colour and material overview in your enquiry helps assign the intended design unambiguously.

One possible buyer example is a façade with clear horizontal lines. Here, a horizontally divided pattern could be considered as a visual reference. In a room with more strongly vertical wall panels, a vertical division may instead be appealing. The important point is to describe such references as personal design intentions. The product itself does not prescribe an architectural style or a particular effect.

Comparing window forms and opening types

A combination window suits projects where several areas are planned as one connected window composition. If a special geometric shape, fixed glazing alone or an explicitly outward-opening design is the priority, it is worth comparing related window types. Start with the basic function and shape before comparing dimensions, material, colour and glazing-bar pattern.

Fixed-glazed window types are available for round, semi-round, triangular and angled openings. The round and semi-round versions are offered in pine or oak. Triangular and angled windows are also available in pine or oak with aluminium cladding. All three product types are non-opening, making them a focused alternative where light and form matter more than an operable sash.

Where an outward-opening window solution is needed, compare the related pivot, top-hung and side-hung windows. These types are offered in pine, pine with aluminium cladding, oak or oak with aluminium cladding, and include a handle choice. The key question is which stated opening type suits the intended use and installation situation; detailed planning then follows for the chosen product.

For access to a patio, consider the related single-leaf outward-opening patio doors. Alongside the regular version, a historic-style option is available. Both are independent door products with their own material, glazing, hardware and design choices. Where windows and doors are used together in one façade, colour, glazing-bar lines and sightlines can be coordinated visually while technical details remain planned for each product.

The following related products provide a direct overview of fixed-glazed special shapes, outward-opening windows and matching patio-door options: Round fixed-glazed window, Semi-round fixed-glazed window, Triangular and angled fixed-glazed window, Outward-opening pivot window, Top-hung outward-opening casement window, Single-leaf outward-opening side-hung window, Single-leaf outward-opening patio door, Historic-style single-leaf outward-opening patio door.

Preparing your enquiry in a clear sequence

Start with a short description of your project. State the building area, internal and external sides, and why you are considering a combination window. Describe observable requirements rather than broad wishes: for example, a particular direction of division, a relationship to neighbouring openings or a preferred material character.

Then include checked dimensions and an easy-to-understand sketch. Mark the viewing direction and show how the total area should be divided. Additional photographs can explain the location, but should not replace a dimensioned drawing. Point out adjacent components that may be relevant to planning or use.

Next, set out the desired material finish: pine, pine with aluminium cladding, oak or oak with aluminium cladding. Note your colour choice and explain whether it should relate to existing façade, interior or component colours. For an unambiguous design, name the glazing-bar pattern using its official designation.

Then describe the expected everyday use. If the selected arrangement includes suitable opening sections, add the preferred handle choice. Also note furniture, work surfaces, curtains or other elements that could affect access. Particular installation requirements and necessary coordination with adjacent components should also be stated clearly.

Finally, check your documents for contradictions: do the dimensions, sketch and viewing direction agree? Is the material finish stated clearly? Are the colour, pane configuration and glazing-bar pattern assigned unambiguously? Has a handle choice been given only for an arrangement with suitable opening sections? A compact, ordered enquiry creates a reliable basis for further discussion of your made-to-measure combination window.

Can I choose the colour of the combination window?

Yes. Colour choice is one of the available purchasing decisions. Consider the façade, adjacent components and interior design so that the frame, cladding and glazing-bar pattern work as one coherent composition.

When can I choose a handle for the combination window?

A handle choice is possible where the selected arrangement includes suitable opening sections. First provide the desired window composition and your everyday-use requirements. It can then be clarified which handle option suits the specific version.

Is the window suitable for an individually sized opening?

Made-to-measure production allows planning around your intended opening. Carefully taken dimensions and information on form, junctions and installation conditions are essential. These details should be professionally checked before the final specification is set.

Which material finishes are available?

Choose from pine, pine with aluminium cladding, oak and oak with aluminium cladding. Decide which of these four finishes suits your project according to the desired material and surface effect indoors and on the façade.

Can I design the glazing-bar pattern freely?

Available options are “SH1 – without glazing bars”, one horizontal glazing bar, one vertical glazing bar, two vertical glazing bars, and a combination of one horizontal and one vertical glazing bar. Select the named pattern whose direction of division best suits the window proportions and façade lines.

What should I consider for future cleaning?

Assess access to every visible glass and frame area during planning. The suitable cleaning method depends on the installation position, accessibility and surfaces. Follow the care instructions for the materials and fittings used.

Which glazing options are available?

The combination window is available with an insulating glass unit of two or three panes. Both options include a heat-reflective coating, a warm-edge spacer marked CHR and argon gas filling. State your preferred pane configuration in the enquiry.

What does CE marking mean for my planning?

The combination window is CE marked. For your specific project, carefully coordinate the dimensions, installation conditions, connections to adjacent components and requirements at the intended location.
