Bloomcabin 2 sashes without decorative bars. Choose a clean, contemporary look with this inward-opening window formed by two sashes without decorative bars. Its uncluttered glazing creates a light visual effect, while the twin-sash layout brings pleasing symmetry and clear definition to the window opening.
Why choose this Bloomcabin design?
Two sashes without decorative bars allow the glazing to take centre stage. The result is a calm, open-looking design that preserves clear sightlines and sits quietly within the wider interior and exterior scheme.
The paired inward-opening sashes give this window a balanced composition without unnecessary visual detail. It is an effective option when you want a crisp profile and a clean division between the two opening sections.
The window supports high energy efficiency and helps maintain a comfortable indoor environment through changing seasons.
Well suited to projects seeking a broad, uncluttered window expression, from contemporary extensions to understated refurbishments. The two inward-opening sashes provide a practical arrangement with a deliberately minimal appearance. Before configuration, the design can be adapted to the project requirements and the preferred architectural character.

A made-to-measure two-sash window combining inward operation, tilt functionality and a choice of timber, cladding and glazing configurations.
Opening
Two inward-opening sashes with tilt function
Material
Pine or oak
Cladding
Optional aluminium cladding
Glazing
Two- or three-pane glazing
Our two-sash inward-opening window combines a practical paired-sash format with operation from inside the room. The window also includes a tilt function, giving you an additional way to ventilate without changing to a different window type. Made-to-measure sizing allows the complete unit to be planned for the individual opening, while the available compositions range from two opening sashes alone to designs that incorporate fixed glazed sections and decorative bars. It is a versatile choice for projects that need an inward-opening rectangular window with clearly defined configuration options.
Material, cladding, glazing and decorative-bar choices allow you to shape the appearance for a contemporary property, a traditional renovation or a carefully coordinated extension. The result can be kept visually simple or developed into a more detailed multi-section arrangement with fixed glazing. Every Bloomcabin window comes with a five-year warranty.
01
The two sashes open into the room, keeping their opening path on the interior side of the window. This inward action is useful where the external elevation should remain free from an outward-moving sash, but it makes internal clearance an important part of the room layout. Consider how the window will be reached and operated in daily use, particularly above furniture, worktops or other fitted elements. The made-to-measure dimensions and selected layout should therefore be reviewed together with the usable space immediately inside the opening.
The window is specified with inward-opening operation and a tilt function. The tilt position provides a more contained opening arrangement for ventilation, while the inward-opening action brings the sash into the room. Allow convenient access to the handle and make sure the chosen handle suits the intended interior arrangement. Roto Frank hardware is used for the opening mechanism, and handle choice is one of the supported configuration decisions. Recording the selected handle with the window reference helps keep functional and visual choices together.
Because the sashes move into the room, reserve clear internal space across their full opening path. Furniture, deep ornaments, taps and other permanent items should not obstruct the movement. Curtains, shutters and blinds also need to be positioned so they do not catch the handle or prevent either sash from opening. Plan that clearance once at the layout stage, particularly where the window is set above a worktop or close to an internal corner.
02
The available material choices are pine, aluminium-clad pine, oak and aluminium-clad oak. Pine and oak offer distinct timber appearances, while the aluminium-clad alternatives combine the selected timber with cladding. This gives you four clearly defined material formats to compare with the architecture, surrounding finishes and other windows in the project. When several units are required, use the same material description on drawings, schedules and enquiries so that an aluminium-clad version is not confused with its unclad timber counterpart.
For pine or oak without aluminium cladding, the frame section is 82 × 78 mm and the sash section is 82 × 78 mm. With aluminium cladding, the frame section is 82 × 88 mm and the sash section is 82 × 88 mm. These measurements describe the stated sections rather than the overall made-to-measure window size. Fixing holes are 14 mm.
Colour choices can be used to relate the window to the exterior finish and the interior palette. When comparing timber and aluminium-clad versions, consider the outside and inside as separate parts of the architectural composition: the exterior may need to sit comfortably with masonry, render, roofing or other windows, while the interior should work with flooring, joinery and wall colours. Keep the selected material, cladding format and colour references together in the project schedule so that all openings are specified consistently.
03
The window is available with a two-pane or three-pane glazing unit. Both choices are specified with a heat-reflective coating, a warm-edge spacer identified as CHR and argon gas. Silicone glazing seals are used. These components form the supported glazing specification, while the choice between two and three panes allows the glazing build-up to be selected for the particular project.
Glazing should be considered alongside the size and arrangement of the window rather than as an isolated selection. A simple two-sash composition presents a different visual balance from a version that combines opening sashes with one or more fixed glazed sections. Decorative bars also divide the visible glass into smaller fields, changing the scale and rhythm even though the underlying window composition remains clearly organised.
The glazing selection should also be reviewed in the context of the complete opening. Consider the window’s position in the elevation, the available daylight, the desired outlook and the visual effect of any fixed sections or decorative bars. For projects with several windows, identify the two- or three-pane choice against each individual unit rather than relying on one general project note. This is particularly helpful where window sizes or compositions vary. Our team can help you compare the supported glazing choices and record the preferred specification when you prepare your enquiry.
04
The most visually restrained listed design consists of two sashes without decorative bars, keeping the glazed fields clear apart from the division between the opening elements. If a more detailed pattern is preferred, the two sashes can instead be specified with one horizontal decorative bar or with two horizontal decorative bars. These three arrangements retain the two-sash format while changing the amount of subdivision visible in the glazing. Choose the exact listed pattern rather than assuming that the number or position of decorative bars can be varied freely.
Other supported layouts combine one fixed glazed section with the two opening sashes. One option has a fixed glazed section and two sashes without decorative bars. A more articulated design adds one vertical decorative bar to the fixed section and one horizontal decorative bar to the two sashes. Another uses one vertical decorative bar in the fixed section and two horizontal decorative bars in the two sashes. Unless a layout is expressly described as central, show the required arrangement clearly on the project elevation rather than relying on an assumed fixed-section position.
A denser listed composition combines one fixed glazed section with two vertical decorative bars and two sashes with two horizontal decorative bars. A separate design expressly places one fixed glazed section in the centre, accompanied by two sashes without decorative bars. The central position belongs specifically to that named arrangement and should not be applied automatically to the other fixed-section options. Compare these layouts using a simple elevation so that the section arrangement and decorative-bar pattern can be read separately and recorded without ambiguity.
A further composition contains two fixed glazed sections and two opening sashes without decorative bars. This provides an alternative when the overall window design needs more fixed glazing while retaining the two opening elements. When reviewing any of the listed patterns, distinguish the boundaries between opening and fixed sections from the decorative bars shown within glazed areas. Record the complete composition by name or drawing, including the number of fixed sections, the two sashes and the applicable bar pattern, so the enquiry does not depend on an imprecise description such as divided or multi-section.
05
Made-to-measure sizing should begin with a clearly identified opening and an agreed measurement basis. Record the opening at several points rather than assuming the surrounding construction is perfectly square, and note any variation that may affect the intended window size. The final order dimensions should be distinguished clearly from structural-opening measurements, finishing dimensions and any dimensions taken from an existing frame.
Use a drawing that shows the window as viewed from a stated side, and keep that viewing convention consistent throughout the project. Mark every opening sash, fixed glazed section, section boundary and decorative bar included in the selected design. Where the composition is not expressly identified as central, do not assume a fixed-section position from the product category alone. A simple labelled elevation is clearer than relying only on terms such as left or right and helps prevent the orientation from changing as information moves between room plans, exterior elevations and order schedules.
Allow the fitting method and surrounding construction to be considered by the person responsible for installation. Sill details, internal reveals, exterior finishes and junctions with adjacent materials should be resolved as part of the building design. Check that the proposed frame position works with both the interior finish line and the exterior elevation. Before ordering, compare the latest site dimensions with the latest drawing revision and resolve any difference between them.
06
The paired-sash format creates a clear recurring element that can be coordinated with other openings without requiring every window to be identical. You may repeat the same composition across an elevation, align selected section divisions with nearby windows or use a larger made-to-measure unit as a distinct feature. Establishing a small number of shared reference lines, such as head level, sill level or an applicable decorative-bar height, can help a mixed group of openings read as one architectural scheme. Check these relationships on the complete elevation rather than judging each unit separately.
Decorative bars can shift the character from restrained to more traditional. Bar-free glazing keeps attention on the two principal sashes, while horizontal bars introduce smaller stacked proportions. Designs that combine vertical bars in a fixed section with horizontal bars in the opening sashes create a more articulated pattern. Compare the complete elevation at scale, because a bar arrangement that looks appropriate on one isolated window may appear too dense when repeated many times.
Material, colour and handle options provide further coordination choices. A handle can be selected as a quiet continuation of the interior scheme or as a more visible accent, but it should be reviewed with other nearby fittings rather than chosen in isolation. Externally, consider how the selected colour relates to wall finishes and other frames. Internally, compare it with timber tones, painted joinery and the amount of contrast you want around the opening.
07
A two-sash inward-opening window is most relevant when you want an inward-opening paired composition. Other formats answer different planning questions. A fixed window removes the need for an opening sash where opening ventilation is not part of the brief, while round and semicircular fixed windows introduce shaped glazing for a distinct architectural feature. The comparison should therefore begin with whether the opening needs to operate and what geometry belongs in the elevation.
A Kombi combination window is worth comparing when the project calls for a combination format rather than the specific paired arrangement described here. If outward movement is preferred, outward-opening products provide another operating direction. The Outward-Opening Passive House Window with Super-Low Uw and the EI30 Fire-Rated Outward-Opening Pivot Window are separately named options for briefs centred on their stated product categories. Any project requirement associated with passive-house or fire-rated construction should be matched to the relevant product rather than inferred from this window.
Doors address circulation as well as glazing and ventilation. The Single-Leaf Patio Doors – Outward Opening and Heritage-Style Single-Leaf Patio Doors – Outward Opening may be considered where an outward-opening door format is required. The heritage-style title also provides a useful visual comparison for schemes seeking a more traditional expression, although window and door selections should still be recorded as separate items.
Start your comparison with four questions: must the element open, should it move inward or outward, is passage through the opening required, and should the shape be rectangular, round or semicircular? You can then consider visual style and any product-specific requirement. The related choices below provide direct starting points for comparing fixed windows, combination windows, specialist outward-opening windows and patio doors. Explore related windows and doors:

A clear enquiry should identify the product as the Two-Sash Inward-Opening Window and give every unit a unique reference, especially when several similar windows appear in one project. Include the required overall made-to-measure size, quantity, pine or oak selection, whether aluminium cladding is required, colour choice, two- or three-pane glazing and preferred handle. Name the exact sash, fixed-section and decorative-bar composition, and include a labelled elevation wherever words alone could leave the arrangement unclear. Keeping this information in one schedule provides a reliable checklist for comparing units.
Attach the relevant elevation or window schedule and state its revision number and date. If the project contains different section arrangements or orientations, show each version separately and match it to the correct unit reference. Keep previous issues for your own records, but identify one drawing and schedule as current so that superseded dimensions, materials or decorative-bar patterns are not mistaken for the intended selection. Before submitting the enquiry, cross-check every unit reference against the latest site dimensions and confirm who is responsible for approving size, composition, colour and viewing orientation.
List any product questions against the individual window reference rather than placing them in a general project note. This keeps each question connected to the relevant size and configuration, particularly where a project combines bar-free sashes, fixed glazed sections and more detailed decorative-bar designs. It is also helpful to flag any item that differs from the main project specification, such as a different timber, aluminium-clad format, glazing choice or handle. Our team can then review the supported options with you and help organise the information needed for your made-to-measure window enquiry.
Two-sash window questions
Yes. The Two-Sash Inward-Opening Window is CE marked. Its individual configuration must still identify the required made-to-measure size, material, glazing, colour, handle and selected section or decorative-bar arrangement.
The tilt function provides an alternative opening position, while the inward-opening position brings the sash into the room. Keep internal obstructions away from the operating area.
Yes. You can choose pine, aluminium-clad pine, oak or aluminium-clad oak. If you choose a clad version, record it explicitly when selecting the material.
Yes. Supported designs include two opening sashes with one fixed glazed section, one expressly central fixed glazed section, or two fixed glazed sections. Decorative-bar arrangements differ between the listed compositions, so select and record the complete design rather than assuming that every bar pattern is available with every layout.
Compare the pattern at the scale of the complete elevation. Bar-free glazing gives a simpler appearance, while one or two horizontal bars create stronger subdivision. Where a fixed section is included, vertical bars can add another visual rhythm.
Yes. Both are available with a heat-reflective coating, CHR warm-edge spacer and argon gas. Consider the glazing choice together with the selected layout and the requirements of your individual project.
Give every window a unique reference and provide a dated elevation showing the viewing side. Mark opening sashes, fixed sections and decorative bars directly on that drawing, and identify one revision as the current approved version.
Send the unit references, overall sizes, quantities, selected design, pine or oak choice, any aluminium cladding, colours, two- or three-pane glazing and handle preference. Include a current labelled elevation where fixed sections, decorative-bar patterns or the viewing orientation need to be communicated clearly.
