Inward-opening sashes and tilt function in everyday use

The product’s operation is fixed by its construction: each of the two leaves moves inwards, and tilting is also available. These give distinct ways to use the window; outward travel is not offered on this model. Full opening requires a clear area inside, whereas tilt holds the leaf at its designed angle. Choose between these positions according to the immediate task, available clearance and arrangement of the room.

Begin by mapping the space through which the sashes will move. A window board, tap, curtain, lamp, item of furniture or other fitting must not obstruct their travel. Consider convenient everyday operation as well as the leaves at their widest opening. If a worktop or furnishing sits nearby, make sure you can still reach the handle and use the planned sash position comfortably. Bespoke dimensions make this review particularly worthwhile, since the unit can be assessed against the actual room. Include busy walking routes and work zones beside the window at an early stage so practical clashes can be addressed while the design is being prepared.

Selecting two sashes also determines the visual composition. They divide the glazed area differently from one opening leaf or an entirely non-opening unit. Assess use and appearance together: this model is relevant when both leaves must operate. If ventilation through the window is not needed, or the leaves must travel in another direction, review the window types designed for those requirements.

02

Timber options, aluminium cladding and frame construction

Four constructions are offered: unclad pine, aluminium-clad pine, unclad oak and aluminium-clad oak. The first decision is the timber species; the second is whether its exterior is to receive cladding. This combination changes both the visible character of the finished window and the relevant section size for its frame components. Review the selection alongside the proposed colour, insulating glass and arrangement so that all parts of the design work together.

For an all-timber window, the stated fixed outer-frame section is 82 × 78 mm; adding aluminium cladding changes it to 82 × 88 mm. The opening-sash section follows the same pair of measurements: 82 × 78 mm without cladding and 82 × 88 mm when clad. Record the selected construction for every unit so the applicable section is clear. Even though their stated sizes coincide on this model, the outer frame and opening frame remain different components. Neither section measurement represents the bespoke width or height being ordered. Linking each figure to its component and material finish keeps the enquiry unambiguous.

The defined equipment includes Roto Frank hardware and installation holes measuring 14 mm in diameter. CE marking is also specified for the window. Those characteristics remain part of the model, while its ordered size, timber, colour, handle and glass option are selected from the choices offered. Bloomcabin covers this window and its doors under a five-year commercial guarantee. Keeping these particulars with the correct model provides a clear configuration record and avoids importing incompatible details from other window designs.

Planning a custom-sized window in advance

Record each required width and height accurately for bespoke manufacture, assigning a separate reference to every window in a multi-unit project. Review the intended opening, nearby construction and the clear area indoors through which the sashes must pass. The section measurements for the outer and opening frames relate to those individual components and do not replace the overall order size. Against each window reference, enter the selected timber and state if aluminium cladding is wanted. A structured schedule keeps dimensions, frame construction and visual arrangement correctly associated from the initial enquiry onwards.

Account for the inward swing before the surrounding room layout is fixed. The free space needed depends on both the window dimensions and what will be positioned close to it. Nearby basins, worktops, window boards and other interior fittings can interfere with operation. Check curtains, blinds, plants and furniture that may be moved into the same area too. Assess the full arc of the sashes, the tilted setting and convenient routine access. Comparing all three considerations with the proposed room arrangement before enquiring can expose likely obstructions and help establish a suitable size and composition.

When fixed panes appear in a pattern, identify their positions at the same time as the overall measurements. Broad terms such as “multi-part” or “with bars” do not distinguish the available designs. Use the exact arrangement description to separate a sash-only design from one containing a single fixed pane, the specifically centred version or the option using two fixed areas. Precise labelling limits the need for clarification and makes the bespoke specification easier to discuss.

06

Coordinating colour, handle and design

The handle and colour may both be specified. Assess these details against the chosen oak or pine and whether the timber will be aluminium-clad. Look at the proposed interior and exterior appearances separately within their respective surroundings. Existing doors, windows, hardware, wall finishes and repeated tones can all guide the selection. Glazing bars also change the prominence of the frame and its finish. Record the handle and colour beside the wood, glass and pattern information. Where several windows are involved, use the unit references to show which selections belong to each one.

Glazing bars make a strong contribution to the overall look. Two uninterrupted sashes have a different balance from patterns using either one horizontal division or two. In layouts with fixed glazing, the named design may also include vertical bars. Review the quantity and direction of every division alongside the colour choice. A pattern name indicates the elements included, but does not define their exact scale, geometry or proportional relationship.

One orderly sequence can simplify selection. Establish the functional arrangement first; then choose its design pattern, followed by timber, cladding, colour and handle, before confirming the glazing. This order is only a practical way to organise decisions, not a technical requirement. It helps keep independent options easy to review and can uncover contradictions before contact. The resulting request can then describe both the intended operation and the preferred visual character with equal clarity.

Suitable alternatives from our window and door range

Start with this model when the brief requires a pair of operable inward-swinging sashes and a tilt position. If the glazing should remain closed, consider the non-opening window instead. Circular and semicircular fixed windows provide alternative shapes, but neither can be opened. A combination window addresses a different assembly of window elements. Consult the separate information supplied for each alternative because its specifications apply only to that design and should not be carried across to the model described here.

Where travel direction is decisive, distinguish these inward-moving sashes from the outward-swinging alternatives. One option is the EI30 pivot fire window, which opens outwards and retains its stated EI30 classification. Another is the Super Low Uw passive-house pivot window, also designed to move outwards. Neither operates like the paired sashes featured on this page. Materials, frame sections and glazing must be checked in the dedicated information for the alternative concerned rather than transferred to this window.

If the opening must provide glazed access, compare the outward-swinging patio door with one sash and its historic-style counterpart. Their movement away from the room is a key distinction from the window presented here. Establish first whether the intended function is a window opening or a doorway. Then use the relevant product information to assess sash count, travel direction, materials and available arrangements. This sequence keeps the comparison focused on the proposed use and the specifications belonging to each design.

EI30 pivot fire window, outward-opening, Super Low Uw passive-house pivot window, outward-opening, Window with combined elements, Non-opening glazed window, Fixed circular window, Fixed semicircular window, Patio door with one outward-opening sash, Historic-style patio door with one outward-opening sash.

Describe the configuration you want

For each window, provide the required width and height, timber construction and preferred 2-pane or 3-pane insulating glass. Follow these with the colour, handle and precise arrangement description. If fixed glass forms part of the pattern, describe the whole composition and distinguish a central fixed pane from a design containing two fixed areas. Give every unit in a multi-window project its own identifier, then place the corresponding measurements and choices under it. State whether the wood is pine or oak and whether it is to be aluminium-clad. This ordered information clearly separates the requested units from the other available designs.

Mention any decisions that are still open. We can explain how the available choices work together, including the ordered dimensions and options for wood, cladding, insulating glass, finish, hardware and pattern. It is fine to make initial contact before settling every detail. The most helpful enquiry describes the intended operation and the visual result you have in mind, while supplying whatever project information is already known. Those priorities allow the remaining product choices to be considered in context.

Can this window be built to my measurements?

It can. Production follows the project dimensions supplied. Set out those measurements clearly beside the chosen construction so the order is properly defined. During planning, reserve enough room indoors for both sashes to complete their inward movement.

What timber finishes may be specified?

Pine and oak are each offered as an all-timber construction or with aluminium cladding, providing a corresponding clad choice for both wood species.

What glass specification is offered?

Select insulating glass containing either 2 or 3 panes. Both builds include argon, heat-reflective treatment and a CHR warm-edge element, together with silicone glazing gaskets.

How do the window sashes operate?

Both sashes swing towards the room, and the window also provides a tilt setting. Leave enough unobstructed interior clearance for whichever operating position you intend to use.

Are versions with glazing bars available?

Yes. Patterns include unbarred glazing, horizontal glazing bars and, in specified combinations containing non-opening glass, vertical bars. Each design is defined by its particular distribution of opening sashes, fixed panes and bars.

Is fixed glazing available in this window?

Yes. Beyond the arrangements formed solely by the paired sashes, designs are offered with one fixed area or with two. One pattern locates the non-opening glass centrally. Quote the chosen arrangement in full in your enquiry so every sash, fixed pane and glazing bar can be placed correctly.

Can the handle and colour be chosen?

Both can be selected. Coordinate them with the timber species, optional aluminium exterior and planned glazing-bar arrangement, and list the choices clearly in the enquiry.

What guarantee applies to the window?

Bloomcabin’s commercial guarantee lasts five years for its windows and doors. Retain the order records and documents that identify the construction and options you purchased.
