Why choose this Bloomcabin design?
With no decorative bars across the sash, the glazing has a clean and uncluttered appearance. This simplicity allows the historic window format to remain the main visual feature.
The single side-hung sash opens outwards, combining practical operation with understated styling. Its plain glazed design suits schemes where subtle historic character is preferred.
Energy-efficient construction supports reliable thermal comfort and helps maintain a pleasant indoor environment as outdoor conditions change.
An appealing choice for heritage-influenced projects that favour restraint over decorative subdivision. The simple proportions work comfortably with traditional surroundings while giving the glazing a calm visual presence. 1 opening sash without decorative bars — Balanced proportions make it easier to coordinate the design with the architecture and the intended appearance of the facade. The proportions, facade arrangement, and intended overall appearance can also be considered together when selecting the final configuration.

Our Historic-Style Single-Sash Outward-Opening Side-Hung Window combines a clear opening format with a useful range of choices. We make it to measure in pine or oak, with your choice of 2- or 3-pane glazing, seven design patterns, colour and handle.
Start with the way you want the window to open and look in its setting. You can then compare the timber, glazing and pattern options against your project’s priorities. The guide below explains each decision separately, including how to prepare the dimensions and when one of our other window or door formats may be a better match.
01
Type: Outward-opening sash.
This is a single-sash, side-hung window that opens outwards. The sash moves towards the exterior rather than into the room, so its opening action does not project into your internal space. Outside the window, however, the sash needs a practical area in which to move. When choosing its position, consider what is immediately beyond the opening as well as how you will approach it from inside.
Handle access is part of the everyday decision. The best position for the window is one where you can reach your chosen handle comfortably without routinely stretching across deep furniture or other fixed room features. Because the product is made to measure, it is worth considering the window’s dimensions and intended position together rather than deciding each in isolation.
For example, if the window will sit above a work surface, consider how you will stand, reach the handle and operate the outward-opening sash. Keeping the internal approach straightforward may matter more than placing furniture tightly beneath the opening. At the same time, look outside and make sure your planned arrangement accounts for the sash’s outward movement. This one room check brings together movement, reach and access before you settle on the configuration.
02
Material: Pine or oak; Hardware: SPILKA, IPA; Fixing holes: 14 mm; Frame: 105 × 57 mm; Sash: 76 × 65 mm.
The main construction choice is between pine and oak. Compare them in the context of the property rather than as an isolated product choice: you may want the selected timber to relate to other timber windows and doors, or you may prefer to make the decision around the colour you intend to choose. Either timber can be considered with the available glazing and pattern options, so you do not need to decide the whole appearance from the material alone.
The adjoining specification gives the frame and sash dimensions separately. Keep those two components distinct when reviewing the product with the person fitting it, as they describe different parts of the window. The 14 mm fixing holes are also part of the construction information that the fitter can take into account. They should not be treated as an instruction to alter the size of the prepared opening without first agreeing the manufacturing dimensions.
SPILKA and IPA are the specified hardware for this product, while the handle is one of the details you can choose. Consider how your preferred handle will work with the selected colour and the room-facing appearance of the window. The glazing seals are specified separately as black rubber. Reviewing the timber, colour and handle together will give you a more complete basis for choosing than focusing on the frame material alone.
03
Glazing: 2- or 3-pane glazing unit with heat-reflective coating, warm-edge spacer (CHR) and argon gas; Glazing seals: Black rubber.
You can select a 2-pane or 3-pane glazing unit. Make this choice while the wider wall and window specification is being planned, particularly if the project includes other windows whose glazing you want to coordinate. The right option is the one that fits the requirements established for your particular building rather than simply the one with the higher pane count.
Both available glazing units include a heat-reflective coating, a warm-edge spacer (CHR) and argon gas. These elements form part of the stated glazing specification. If glazing performance is central to the project, ask the person planning the building to compare the 2- and 3-pane choices in the context of the complete opening and surrounding construction. That keeps the decision tied to the project instead of assuming that the glass alone determines the result.
The glazing seals are black rubber and form part of the product specification rather than a separate purchase choice. When comparing the glazing options, distinguish between the pane count you can select and the features common to both choices. Record the agreed pane count clearly with the rest of your configuration so that the glazing, made-to-measure dimensions, timber, colour, handle and design pattern can be reviewed as one complete order.
04
Seven design patterns are available: 1 opening sash without decorative bars; 1 opening sash with 1 horizontal decorative bar; 1 opening sash with 1 vertical decorative bar; 1 sash with 1 horizontal decorative bar and 1 vertical decorative bar; 1 sash with 1 horizontal decorative bar and 2 vertical decorative bars; 1 sash with 1 horizontal decorative bar and 3 vertical decorative bars; and 1 opening sash with 2 horizontal decorative bars and 1 vertical decorative bar.
For the simplest appearance, choose the design named “1 opening sash without decorative bars”. It leaves the sash visually undivided and keeps attention on the proportions of the made-to-measure window. This may suit you if the historic-style frame is the main feature you want to emphasise or if nearby windows have an equally restrained arrangement.
The design “1 opening sash with 1 horizontal decorative bar” introduces one horizontal division. It can make the composition feel more layered without adding vertical sections. By contrast, “1 opening sash with 1 vertical decorative bar” adds a single upright division, so the eye reads two side-by-side areas instead. Compare these designs according to the direction already established by neighbouring frames or architectural lines.
For a balanced combination in both directions, “1 sash with 1 horizontal decorative bar and 1 vertical decorative bar” uses one bar each way. If you want more vertical rhythm, “1 sash with 1 horizontal decorative bar and 2 vertical decorative bars” increases the number of upright divisions while retaining one horizontal line. Each is an individual pattern, so compare the complete arrangement rather than choosing merely on the basis that both contain horizontal and vertical bars.
The pattern “1 sash with 1 horizontal decorative bar and 3 vertical decorative bars” creates the strongest vertical repetition in the range while retaining a single horizontal bar. Alternatively, “1 opening sash with 2 horizontal decorative bars and 1 vertical decorative bar” places greater emphasis on repeated horizontal divisions crossed by one vertical bar. Consider the finished width and height when comparing these denser patterns, as the made-to-measure proportions will influence how closely grouped the divisions appear.
05
Suppose you are replacing a window in an existing wall. Begin by identifying the finished surfaces that will define the usable opening once the old product is removed and the surrounding work is complete. Measure between those surfaces, not from an unrelated trim edge or from a rough point that will later be covered. Record width and height clearly so there is no ambiguity about which figure is which.
An opening measurement and a manufacturing size are not automatically the same thing. Before we make the product to measure, give the recorded information to the person fitting the window and agree the final dimensions with them. They can interpret the actual opening in relation to the installation they are planning. Do not make your own unconfirmed deduction from the measured width or height, as that could separate the order size from the fitter’s intended approach.
The same principle applies in a new wall. The person preparing the opening and the person fitting the window should work from an agreed set of dimensions, with the finished surfaces understood by everyone. It is also useful to confirm which side is the exterior, because the sash opens outwards. Once the manufacturing width and height have been agreed, use those figures consistently when selecting the pattern and reviewing the window’s proportions.
06
One visual direction is to make the window feel closely coordinated with the property. You could choose a colour that relates to neighbouring window frames, outward-opening doors or recurring facade details, then select the decorative-bar pattern that most closely follows their established lines. If other openings have a simple treatment, the design without decorative bars may be the calmer match; if bars are already prominent, compare their horizontal and vertical emphasis with the seven available patterns.
A contrasting direction is to let this window read as a distinct historic-style feature. Consider a colour that gives the frame a clearer presence against the surrounding facade, then decide how much pattern the opening can carry. A single horizontal or vertical bar provides a restrained accent, while one of the combined arrangements creates a more structured appearance. This should still be a considered contrast: look at adjacent doors, roof windows and other facade openings before deciding how strongly the window should stand apart.
Inside the room, the selected frame colour and handle will contribute to the window’s appearance. You could coordinate the handle with other visible details or use it as a small point of contrast, depending on the effect you prefer. Also consider the view through the window: decorative bars form part of the composition from either side, so a pattern that suits the façade should also feel appropriate from your usual position in the room.
Pine or oak adds another layer to the decision, but it is best judged as part of the whole configuration. Compare your preferred timber with the available colour, your handle choice and the architectural details around the opening. This helps you arrive at a window that works with the façade while also giving the room-facing frame and handle a considered appearance.
07
First compare this window with formats that retain an outward-opening, side-hung description. Our Historic-Style Two-Sash Outward-Opening Side-Hung Window changes the composition from one sash to two, so it is the most direct comparison if the number of sashes is your main question. The Kombi Outward-Opening Side-Hung Window and Historic-Style Kombi Outward-Opening Side-Hung Window give you Kombi alternatives; compare the historic-style version if that character remains an essential part of your brief.
If you prefer a different window movement, consider our Single-Sash Outward-Opening Vertical Pivot Window. It keeps a single-sash format but changes the named operation from side-hung to vertical pivot. The Two-Sash Outward-Opening Vertical Pivot Window gives you the corresponding two-sash format. Compare these names carefully against how you want the product to be arranged and operated rather than assuming every outward-opening window is the same.
For a roof position, the Pivot Roof Window is the relevant format to review. Where the opening needs to function as a door, compare the Single-Leaf Patio Doors – Outward Opening and the Heritage-Style Single-Leaf Patio Doors – Outward Opening. Their names identify them as patio doors rather than windows, with a single-leaf outward-opening format; the heritage-style option is the closer comparison if historic or heritage character is important.
Use the alternative list to settle the broad format before refining this window’s detailed choices. Decide whether you need a window or patio door, a wall or roof product, one sash or two, and side-hung or vertical-pivot operation. If those decisions bring you back to one historic-style side-hung sash opening outwards, this product is the appropriate starting point for timber, glazing, pattern, colour and handle selection.

To make the final choice, identify the one priority that should lead the project. It might be retaining a simple view, coordinating with divided neighbouring windows, matching a historic-style facade, or choosing the format that works best in the intended position. Compare no more than two preferred configurations against that priority first; this makes the meaningful difference easier to see.
For example, if you are deciding between the design without decorative bars and a pattern combining horizontal and vertical bars, ask which better supports the surrounding architecture. Once that is settled, choose pine or oak, select the 2- or 3-pane glazing in line with the project plan, and coordinate the colour and handle. If two configurations still feel equally suitable, use the room-facing frame colour, handle and decorative-bar pattern as the deciding perspective.
Before ordering, make sure the agreed manufacturing dimensions describe the same configuration you have chosen and that outward opening remains right for the location. If you would like help comparing your final two preferences, contact us with the intended format, dimensions and the options you are considering. We can then discuss this made-to-measure window on the basis of the choices available.
