Internal crittall doors: heritage profiles, custom-made

An internal crittall door divides a room without closing it off. The slim 30 millimetre aluminium profile and the multi-pane glass let light pass through freely, which is why crittall-style doors have become the default choice for open-plan layouts that need a degree of separation without losing the sense of space.

Emezzi’s internal crittall-style doors are powder-coated aluminium with the heritage multi-pane look. They are made to measure and fitted across the UK.

Internal crittall doors that let light flow between rooms

Think of a knocked-through Victorian house where the kitchen and living room share the same space. It works well for everyday life, but sometimes you want to close the cooking smells off from the sitting room, or create a quieter zone without building a solid wall.

An internal crittall door with glass does exactly that. When it is closed, the room still feels connected. The light still moves between the two spaces. The separation is defined, not absolute, and that is precisely the point.

Where internal crittall doors work best

Kitchen-to-living-room transitions in open-plan layouts are the most common use of crittall doors. Internal crittall doors for the living room suit both contemporary and period homes, and the multi-pane grid reads particularly well in Victorian and Edwardian properties where the sash windows already divide the glass into a similar pattern.

Hallway-to-living-room openings in period terraces are another natural fit, as are study and home office entrances where you want a visual separation from the rest of the house without feeling shut away. Ensuite-to-bedroom transitions and dining-room-to-snug door openings in larger homes are also popular configurations.

For period properties specifically, internal crittall doors in a Victorian or Edwardian house are one of the most period-appropriate door choices available. The slim profile respects the original room scale in a way that a chunky modern door never quite does.

Why choose an overlay door?

Configure your internal crittall door

Design your internal crittall door step by step in our configurator. Choose your door type, enter your dimensions, and select your bar layout. The configurator previews how a three-pane, four-pane, or six-pane layout reads in your specific opening before you commit. The price updates in real time.

Bar layout: 3-pane, 4-pane, 6-pane or custom

Glass options for internal crittall

Opening type: pivot, hinged, sliding or flush

Bar layout: 3-pane, 4-pane, 6-pane or custom

The bar layout defines the character of an internal crittall door more than any other choice. A three-pane vertical layout suits taller, narrower door openings and gives a clean, elongated look that works well in rooms with high ceilings.

A four-pane layout with one horizontal cross-bar is the all-rounder. For a standard 210 centimetre-high door opening, it is the most-specified configuration and works across a wide range of interior styles. A six-pane layout gives stronger heritage character and suits period properties where you want the crittall internal door to read as authentically as possible. Fully glazed is available for those who want the slim aluminium frame without any bar divisions.

Proportions matter here. The configurator helps you get them right before you place an order.

Glass options for internal crittall

Clear laminated safety glass is the standard for most internal crittall doors. Frosted or reeded glass suits study and bedroom door openings where privacy matters alongside the light. Bronze or grey tinted glass suits more design-led schemes where the glass colour is part of the overall palette. All glass is laminated safety glass as standard across the range.

Opening type: pivot, hinged, sliding or flush

All four opening styles are available as internal crittall doors with glass. A hinged door is the most traditional and respects the scale of period properties best. A pivot door adds drama and suits taller door openings where a standard hinged door would feel too modest.

A sliding crittall door suits tight floor plans where the swing of a hinged door would be impractical. A flush crittall door is the minimalist option. It levels with the wall surface for a clean, uninterrupted line.

Finishes for internal crittall doors

Matt black RAL9005 is the most-specified finish for internal crittall doors and the closest match to the original steel aesthetic. White suits 1930s and Georgian properties where black would read as too industrial. Bronze and gold are available for warmer, more distinctive schemes, and any RAL colour is supported so the door can match any interior palette precisely.

Internal crittall in a Victorian or Edwardian home

Victorian and Edwardian properties are the single most common context for internal crittall doors in the UK. The slim 30 millimetre profile respects the original room scale better than a chunky modern door, and the multi-pane grid echoes the proportions of the original sash windows that most of these homes still have.

Matt black RAL9005 is the most period-appropriate finish for Victorian and Edwardian interiors, where the black ironwork of the original architecture sets the tone. White crittall is popular for 1930s properties, where the original Crittall steel windows were often finished in white rather than black.

For crittall doors in a kitchen, the configuration most often pairs a single hinged door with one or two fixed side panels, which fills the full width of a knocked-through opening and keeps the visual line consistent across the wall.

Custom-made dimensions, fitted across the UK

Every Emezzi internal crittall door is made to measure. Our advisor visits your home for a measurement visit, confirms the door opening dimensions, and checks whether the existing opening needs any preparation before the new aluminium frame goes in.

The maximum width per panel is 150 centimetres. Do you have wider door openings? Fixed side panels with transoms or a double-door configuration extend the system without breaking the visual line. The door is manufactured in our workshop and installed by Emezzi-authorised dealers across the UK. Read the answers to your questions about lead times and installation.

Thinking about pairing your internal crittall door with a room divider configuration or French crittall doors elsewhere in the house? The 30 millimetre profile runs consistently across the full range, so every door reads as part of the same system.

Frequently asked questions about internal crittall doors

Most people asking about internal crittall doors are mid-renovation and want practical answers about proportions, installation, and what to expect from the door in their specific room.

Is your question not listed?We’er happy to help!

How many panes should an internal crittall door have?

For a standard door opening around 210 centimetres high, a four-pane layout with one horizontal cross-bar is the most-specified default. It works across a wide range of room heights and interior styles. Go to six panes for period properties where you want the heritage character to read more strongly, or choose fully glazed for a modern minimalist interior where the slim frame is the feature rather than the bar divisions.

Can I install internal crittall doors in an existing door opening?

Most existing door openings are suitable for an Emezzi internal crittall door without significant preparation. Hinged variants are installed with a new aluminium frame within the existing opening. Pivot and sliding doors are installed directly into the prepared opening without a separate frame. Our installer confirms the exact detail and any reinforcement needed during the measurement visit.

Will internal crittall doors block sound between rooms?

Internal crittall doors with single-glazed safety glass offer modest sound reduction. They are primarily a visual divider rather than an acoustic seal, so normal conversation will still carry between rooms. For better sound isolation, a rebated double-door configuration is worth discussing during the measurement visit.

Are internal crittall doors expensive?

The all-in price depends on the size, glass type, and opening style you choose. The configurator shows the full price including the measurement visit and installation before you commit to anything, so there are no surprises. Internal crittall doors from Emezzi are typically priced at a fraction of what an equivalent true Crittall steel style door would cost, with comparable lead times measured in weeks rather than months.

What is the lead time for an internal crittall door?

The typical lead time is six to ten weeks from signed quote to installation, subject to current production levels. The process runs in four steps: quote acceptance, measurement visit, manufacture, and installation. After you confirm your order, the dealer schedules the measurement visit within a fixed window.
