Bloomcabin 1 sash without decorative bars. Free of glazing-bar interruptions, this Passive House window provides a clear outlook. Its one opening leaf makes the generous pane prominent, giving modern façades a disciplined, linear character.

What sets this Bloomcabin design apart?

  1. Unbroken glazing

    A single leaf without bars keeps the glazing visually continuous. The window feels light and contemporary, while extra divisions do not interrupt the view outdoors.

  2. Purposeful simplicity

    Attention rests on the window's proportions, frame and glass rather than ornament. This restrained treatment suits architecture that relies on composure, clarity and quiet visual order.

  3. Energy-efficient comfort

    Created for strong energy performance, this Passive House window also supports comfortable rooms.

Choose it for Passive House-led new construction or renovation when one opening leaf and uninterrupted glazing fit the brief. Its pared-back character suits current building envelopes and daylight-focused interiors. Let the window's proportions, the façade and the wider architectural language guide the selection. Before finalising the arrangement, consider its shape, the elevation's ordering and the visual effect you want. The pane remains the defining feature.

Super-Low Uw Passivhaus window with an outward-pivoting sash

A pivot sash designed to travel outwards when opened

Super-Low Uw passive-house window that opens outwards

Made to requested dimensions, this pine passive-house window uses specialist insulation, a defined insulating-glass build and a pivot sash travelling outwards. Choose its frame finish, handle and glazing-bar arrangement.

Opening type

Pivot sash opening outwards

Frame material

Pine incorporating a specialist thermal-insulation material

Glazing

Coated triple insulating glass with warm edge and argon

Marking

CE marked

A pine frame containing specialist insulation supports the sash, which pivots towards the exterior. Its three-pane insulating unit is specified with argon, reflective coating and a CHR warm-edge spacer. The basic construction remains defined, while dimensions are made to order and the frame finish and handle may be selected individually.

The outward travel suits schemes that intentionally keep the sash movement beyond the room. Bar arrangements range from an understated appearance to stronger upright, horizontal or finely divided lines, without changing the one-sash construction. Review the required exterior movement area together with the preferred geometry, frame finish and handle. Below, we explain routine operation, the frame and fittings, insulating-glass specification, available visual arrangements, and what to include when requesting an accurately configured window.

01

Using the outward-pivoting sash day to day

Opening turns the pivot sash towards the exterior rather than into the room, which defines how this model operates. During everyday use, leave its complete travel path unobstructed and move it in a controlled manner with the handle. The handle, not the glazing seals or frame edges, is the proper point from which to guide the sash.

Move the sash steadily in both directions and keep the action deliberate. Should you notice resistance, stop instead of tugging, pushing harder or trying to force it onwards. Look first for objects within its arc and for anything lodged where the movable and fixed frames meet. Gentle, attentive handling promotes comfortable operation of the moving components.

The handle is visually noticeable and touched frequently, so it merits consideration during design planning. Since a choice is available, both appearance and individual preferences for operation may guide selection. It remains a configurable detail rather than a different operating system: every offered handle accompanies the same outward-pivoting window arrangement.

Before closing the sash against its frame, confirm that nothing is trapped between them. Black rubber seals belong to the stated glazing assembly and are not intended as handholds or pulling points. Clean visible parts carefully with suitable methods when required, and keep sharp-edged tools or aggressive treatment away from the frame, glass, seals, fittings and their finished surfaces.

How the outward movement works in daily life depends on the particular installation. In a kitchen, the room remains free from an inward-swinging sash, while sufficient space must be allowed outside. In a study, desks, shelving and reach to the handle can influence the layout. Assess the indoor operating area and external swing space together.

02

Construction, components and technical dimensions

Pine and specialist insulating material form the window construction. The fixed outer-frame section is 105 × 57 mm, while the moving sash section is 90 × 65 mm. Each pair of figures describes that particular frame member, not the completed window's overall height, width or depth. Overall exterior size follows the made-to-order dimensions stated in the request.

14 mm fixing holes are provided for installation. This dimension relates to the fixing holes, not to the ordered window size or the structural opening. For installation planning, record the actual opening, desired window dimensions and intended building connection separately. Clearly labelling dimensions helps coordination and avoids confusion between component and project measurements.

SPILKA fittings are specified for the window, whereas the visible handle can be selected to complement the intended appearance. In the enquiry, list that preference independently of frame finish, ordered dimensions and bar layout. Doing so keeps the chosen handle clear without suggesting any change to the fixed hardware specification or outward pivoting operation.

This window is CE marked and supplied with a 5-year commercial guarantee. The first detail identifies the declared product marking and the second states the applicable guarantee duration. When assessing several windows, place both beside the frame data, glass specification and opening method, keeping construction information clearly distinguished from conditions connected with purchase.

Treat the technical figures as details of individual parts rather than as a complete installation size. Fixed frame, moving sash, glass unit, seals, fittings and fixing holes each serve a different purpose. Begin planning with the made-to-order window required for the site opening; use the section measurements only to understand the model's defined construction.

03

Glazing construction and clearly specified glass features

This is a three-pane insulating-glass unit. Its stated build incorporates argon, reflective coating and a CHR warm-edge spacer. Together they make up the prescribed glass specification for this Passivhaus window; none is offered as a stand-alone decorative option.

Heat-reflective coating is specified within the glazing itself. Keep this separate from the frame-finish choice when planning: one is incorporated into the insulating unit, while the other determines the selected appearance of the individually configured window.

Record the term “warm edge (CHR)” in full on technical schedules. This complete wording makes the relevant glass construction identifiable where several windows or differing specifications appear within one scheme.

Argon is supplied within the defined triple insulating unit rather than chosen independently. The configurable details are the requested dimensions, frame finish, handle and preferred option from the stated selection of glazing-bar layouts.

The glazing assembly also uses black rubber seals. Their black finish is predetermined, unlike the frame finish you select. When assessing the completed appearance, review the frame colour, handle, glazing-bar arrangement and window proportions as a coordinated composition.

04

Glazing-bar layouts and their names

The most restrained option is “1 sash without glazing bars”. With no additional lines dividing the glazed view, attention remains on the single sash and its uninterrupted glass effect. The custom-sized window still retains the specified pine-and-insulation frame construction and the established triple insulating-glass assembly.

“1 sash with 1 horizontal glazing bar” introduces a line across the glass, whereas “1 sash with 1 vertical glazing bar” creates an upright division. Each layout uses one orientation, but the resulting proportions are different. Decide which works better by studying the lines of the surrounding façade and interior.

In the layout “1 sash with 1 horizontal and 1 vertical glazing bar”, an upright line and a crosswise line intersect in the same design. It produces greater visual subdivision than either single-line alternative, but the window continues to have one movable sash. The apparent glazed fields are not separate opening units.

“1 sash with 2 horizontal glazing bars and 1 vertical glazing bar” strengthens the divisions across the window. The options named “1 sash with 3 horizontal and 1 vertical glazing bar” and “1 sash with 4 horizontal glazing bars and 1 vertical glazing bar” develop the same idea with progressively closer horizontal spacing. This allows the visual rhythm to be adjusted to the architecture.

The layout “1 sash with 1 horizontal glazing bar and 2 vertical glazing bars” gives greatest emphasis to two upright lines, intersected by one crosswise bar. It is visibly distinct from arrangements using several horizontal divisions with a lone vertical. When comparing designs, examine not merely the bar count but also orientation, rhythm, window proportions and the façade around it.

05

Assessing the intended opening carefully

Before enquiring, take careful readings across the intended building opening. One measurement or an assumed nominal size is insufficient, as checks at different points can expose variation. Give each recorded value a precise label and reference, keeping opening measurements clearly distinguished from the finished custom-window size being sought.

Custom manufacture means that the opening itself must guide size planning; frame-section figures cannot replace site measurements. Allow for the intended installation build-up and identify the information needed at the building junction. If a contractor will fit the window, agree the measuring approach and all reference points together before submitting an enquiry.

The sash opens outwards. Adequate clear space outside is therefore required for its intended swing. Check potential obstructions such as projecting building elements, exterior equipment or other items nearby. This check concerns the actual movement area at the planned installation position, rather than the size of the room inside.

Include access to the handle in your checks. Even though the sash travels outdoors, a deep worktop, nearby furnishing or another element inside may make the handle awkward to reach. Account for those project conditions while positioning the unit. Afterwards, select a handle suited to both the intended grip and the visual scheme.

Finally, consider the opening alongside the chosen glazing-bar composition. The same line pattern can look different in different window formats. A simple scaled drawing helps assess horizontal and vertical bars in relation to the planned window and adjacent building elements. Mark the window position, dimensions and full glazing-bar pattern name on it.

Colour, linework and the overall visual composition

This Passivhaus window can be ordered in a selected frame colour, helping it sit within the project's wider palette. Identify the required shade as precisely as possible beside the dimensions, handle and bar layout in your request. Where several windows are involved, assign a finish to each position, particularly when the scheme calls for more than one treatment.

Frame colour is seen alongside the glass area, visible timber sections and geometry created by glazing bars. A clear pane arrangement may draw attention to the frame differently from one with numerous divisions. Decide whether the finish is meant to recede into neighbouring materials or contribute deliberately to the façade's pattern.

The handle also affects how the whole window looks. Consider its form and surface treatment with the selected frame shade and bar pattern, then describe the desired version accurately. On schedules covering multiple windows, connect each choice to its correct position. These selections surround the established structure and outward-moving pivot mechanism.

Black rubber seals belong to the specified glass assembly; their fixed appearance should not be confused with the frame finish you choose. For a convincing overall result, coordinate the requested colour, handle style and glazing-bar directions. Review all three against the amount of visible glass and the window format, considering how the custom unit will read indoors and on the façade.

For a quiet appearance, choose glass without bars or a pattern containing only 1 horizontal or 1 vertical bar. The named alternatives with extra divisions in either direction produce a stronger visual structure. A scaled sketch noting window format, frame shade and bar direction can express the preferred composition clearly and accurately.

07

Comparing suitable windows and doors for other openings

For schemes containing more than one opening, assess the required operation, outline, material and glass specification at every position. The model described here pairs an exterior-pivoting sash with pine, specialist insulation and a three-pane insulating unit. Elsewhere in the scheme, a non-opening glazed unit, another exterior-opening mechanism or a glazed patio entrance may serve the intended use more effectively.

Where ventilation is unnecessary, select a fixed-glazed product. The related selection covers a standard rectangular window as well as round, semicircular, triangular and angled forms. Individual specifications provide pine or oak frames, with exterior aluminium cladding on certain versions, and either double or triple insulating glazing. Match every site position to the features declared for the particular product under consideration.

Other windows opening towards the exterior provide different ways for the sash to move. Related pivot and top-hung awning versions specify SPILKA fittings, double or triple insulating glazing, and selectable size, finish and handle. Pine, oak and aluminium-clad timber variants add material options for positions that call for another exterior treatment.

At floor level, or wherever the opening must permit passage, consider the related one-leaf patio-door designs that swing outside. The regular door is offered in pine or oak, including aluminium-clad versions; the historic-style door uses pine or oak. Fittings come from SPILKA and ASSA, with a 3-point lock. Depending on the chosen design, the specification includes double or triple insulating glazing and may include a panel.

Compare the linked items by movement, shape, frame material, glass specification and appearance for each planned location. Decide separately whether the position needs a non-opening glazed unit, an operable window or a patio entrance. Recording the decision by opening keeps each chosen element associated with its particular purpose and published specification.

08

Preparing a precise enquiry, step by step

Start by recording the complete product designation: “Super-Low Uw passive-house window that opens outwards”. Using the full name separates it from non-opening glass units, alternative pivot windows, top-hung models and doors. If several openings belong to the scheme, assign each one a brief, intelligible reference so its measurements and aesthetic selections cannot be attached to the wrong location.

Next, collect every particular required for made-to-order manufacture. Give each measurement a clear description and state whether it refers to the structural aperture or finished window requested. Include notes about the installation setting and the unobstructed outdoor area available to the pivot sash. When formats vary across several positions, organise the details in a table or numbered schedule.

Choose one of the glazing-bar arrangements and quote its stated designation exactly. This prevents upright and crosswise bars, or their quantities, being confused. Any accompanying sketch should carry the position reference already assigned to the measurements. Treat the drawing as supporting information; the written layout designation remains essential for identifying the required design.

List the chosen frame finish separately from the preferred handle. Keeping these visible options apart makes assignment to each window position straightforward. Add the selected glazing-bar layout and verify every design entry against the sketch. The SPILKA fitting system and pivot sash opening towards the exterior remain fixed elements of the window’s construction.

As a final review, examine the complete schedule: product designation, position, dimensions, glazing-bar layout, finish and handle. Confirm that terminology is consistent between notes, drawings and the enquiry and that each measurement has an unmistakable reference. This review helps prevent misunderstandings and supports the next discussion. Clearly mark any undecided design point and raise it as its own question.

Your questions answered

Frequently asked questions on this Passivhaus model

Is this passive-house window made to order?

Yes. The unit is produced in the size requested. With the enquiry, submit dimensions carefully taken from the proposed aperture. Your planning should also allow for the installation arrangement and the clear outdoor area through which the sash will pivot.

May I select the window's frame colour?

Yes. Frame finish is among the selectable details, but availability is limited to the colours offered rather than any imaginable shade. Name the exact colour required in your request, allowing it to be considered and recorded unambiguously beside the remaining project information.

Can the handle be chosen?

Yes. Alongside custom dimensions and frame colour, you may specify a handle. Record the desired version with the chosen colour and named bar pattern. The window continues to use its fixed SPILKA hardware system.

Which materials are used in the frame?

The frame combines pine with specialist insulating material. Its fixed section has component dimensions of 105 × 57 mm; the pivoting sash section is 90 × 65 mm. These are construction-section figures only. The overall made-to-order window size is established independently from the project requirements you submit.

Which glazing-bar designs are provided?

Options begin with “1 sash without glazing bars” and continue through layouts using horizontal bars, vertical bars or both orientations. They range from one simple division to denser compositions. Quote the chosen layout's full designation when requesting the window, ensuring both the number of bars and their directions are recorded without ambiguity.

What is the window's opening action?

A pivot sash carries the window towards the exterior when opened. That is the defined mechanism for this model and differs from inward-opening side-hung, tilt-only and tilt-and-turn arrangements.

What makes up the glazing?

The specified three-pane insulating unit contains argon, reflective coating and a CHR warm-edge spacer, together with black rubber seals.

What information should accompany my window enquiry?

Send the opening measurements, exact glazing-bar layout, requested frame colour and preferred handle. Where useful, include notes explaining the architectural context or position. Presenting these items under one position reference allows the proposed combination to be reviewed coherently.
