French doors are a matched pair of doors that meet in the middle and open from the centre, with glazing over most or all of each leaf. That is the whole definition, and everything else follows from it. Internally they turn two rooms into one without losing the ability to close them off. Externally they connect a living space to a garden with a wider, more symmetrical opening than a single door can give.
This guide covers what French doors actually are, how internal and external sets differ, the styles and materials available, the standard UK sizes, our own live prices, the safety glazing rules that apply to any glass at low level, and the hardware a pair needs that a single door does not. Doors2Floors has supplied doors and flooring to homes and businesses across the UK, and the prices here are our own live figures rather than industry estimates.
What French doors actually are
A pair that opens from the centre
Two leaves hung on opposite jambs, meeting at a central joint. There is no fixed mullion between them, which is what gives the wide clear opening.
Mostly glass, by definition
A French door is a glazed door. If the leaves are solid, you have a pair of doors rather than French doors. The glazing is the point.
Rebated pairs versus flush pairs
On a rebated pair the meeting stiles are machined so one leaf laps over the other, which closes the central joint against light, draughts and sound. On a flush pair the leaves simply butt together and need a separate astragal or a flush bolt arrangement. All three of our French pairs are rebated.
Where the name comes from
The form developed in French Renaissance architecture, where full height glazed doors opened from reception rooms onto terraces. The proportions have barely changed. Our short history of the door covers how these patterns spread, in our history of doors.
What they are not
They are not bi-folds, which fold and stack. They are not sliding doors, which pass one leaf behind another. They are not room dividers, which usually combine a pair with fixed side panels.
The active and the passive leaf
In everyday use one leaf is bolted shut and the other is used as a normal door. That passive leaf is released when you want the full opening. Getting this arrangement right at the hardware stage is what makes a pair pleasant to live with.
Internal French doors versus external French doors
What internal pairs are for
Dividing a through lounge, closing off a dining area, separating a kitchen from a snug, or giving a home office a door that still lets light through. They are a light borrowing device as much as a door.
What external pairs are for
Connecting a living room, kitchen or dining room to a garden, patio or balcony. Weather performance, security and thermal performance all become primary concerns.
Thickness and construction differ
Internal doors are typically 35mm thick. External doors are usually 44mm and are built to resist weather and forced entry. An internal French pair must never be used in an external opening.
Glazing differs
Internal pairs use single glazing, usually toughened. External pairs need insulated double or triple glazed units, and the frame has to be designed to carry them.
Weather sealing differs
An external pair needs a weather bar, a proper threshold, drainage and compression seals. Our guide to door U values explains the thermal side, and our notes on draughty doors cover what happens when the sealing is wrong.
Security differs
An external pair needs a multipoint lock, and the passive leaf needs shoot bolts top and bottom. An internal pair typically needs nothing more than a latch and a flush bolt.
What we stock for each
Our 3 French door pairs from £407.44 are all internal rebated pairs. For external openings we carry over 90 external doors from £86.79, including over 30 glazed external doors from £274.81 and 18 composite external doors from £725.00.
Our French door pairs and what they cost
Rather than quote industry averages, here is exactly what we sell. All three are internal rebated pairs at 1981mm high, and the width quoted is the overall pair width.
LPD Mexicano Pattern 10 rebated pair with clear glass
Our entry point at £407.44, available in overall pair widths of 1168mm, 1219mm, 1371mm and 1524mm, which are the 46, 48, 54 and 60 inch imperial pair sizes.
LPD Vancouver Pattern 10 fully finished rebated pair
£527.50, in overall pair widths of 1067mm, 1168mm, 1220mm, 1372mm and 1524mm. Fully finished means no site decoration is required.
LPD Coventry fully finished rebated pair
£570.42 in the 1168mm, 1220mm, 1372mm and 1524mm pair widths, and £586.25 in the two narrowest options at 914mm and 1067mm. The narrow sizes carry a small premium because the glazing and rail proportions have to be reworked.
Why the price does not fall with width
Within a given pattern the price is usually flat across most widths, because the cost is in the glazing, the machining and the finish rather than in the timber area. That is worth knowing, because it means going up a size is often free.
What the pair price includes
The two leaves and the glazing. Frames, linings, hinges, handles and bolts are separate, and on a pair they add up faster than people expect because you need two of most things.
Budgeting the whole job
Add a lining or frame, three pairs of hinges per leaf on a tall glazed door, a latch, a pair of handles per leaf and a flush bolt set. We list over 30 internal frames and linings, over 20 butt hinges from £5.61, over 280 handle packs from £8.99 and over 720 locks and latches from £1.92.
Where a pair is not the cheapest answer
If the goal is simply a wider opening, a single wide door or a room divider may cost less overall once hardware is counted. Our 17 room dividers start at £498.06 and include the side panels.
French doors compared with the alternatives
French pair versus bi-fold
A bi-fold stacks its leaves to one side and gives a much wider unobstructed opening. A French pair gives a symmetrical opening and looks more traditional, and it has far fewer moving parts to go wrong. We stock 15 bi-fold doors from £131.35, and our guides on how bi-fold doors work, bi-fold door ideas and bi-folding door costs cover the comparison properly.
French pair versus sliding doors
A slider needs no swing space at all, which matters in a small room or on a narrow patio. A French pair needs the swing clearance but seals better and looks better closed. Our 16 sliding door kit systems cover the track hardware.
French pair versus pocket doors
A pocket door disappears into the wall and takes no floor space, but it needs a stud cavity and it cannot be glazed edge to edge in the same way. We list 4 pocket doors.
French pair versus a room divider
A room divider is a pair plus fixed glazed side panels, filling a wide opening in one certified unit. If the opening is wider than about 1.5m, the divider is usually the better looking answer. Our 17 room dividers run from £498.06 up to just under £1,400 depending on width and finish.
French pair versus a single wide door
A single 838mm leaf is cheaper and simpler, but it swings a long way into the room and it looks off centre in a wide opening. Our guide to UK internal door sizes covers where the single door limit sits.
French pair versus a cased opening
Leaving the opening without doors is free and gives the best flow, but it loses all acoustic separation and all heat zoning. If you have young children or work from home, that separation is usually worth more than the flow.
Which to choose for a through lounge
An internal French pair in the original chimney breast opening is almost always the right answer, because it respects the original proportions of the room.
French door styles
Pattern 10
Ten glazed panes in a two by five arrangement, in a plain contemporary frame. It is the most popular current pattern and both our Mexicano and Vancouver pairs use it.
Fully glazed single pane
One large sheet per leaf. Maximum light, minimum visual interruption, and the cleanest modern look. It shows every mark on the glass.
Traditional multi pane Georgian
Small panes divided by glazing bars. Correct in a period property, more work to clean, and it cuts more light than people expect.
Half glazed with a solid lower panel
Glass above, timber below. More robust at kick height and a sensible choice where children or pets use the room. It also sidesteps some of the low level glazing concerns.
Shaker and cottage influenced pairs
Plain square edged frames with clear glass, sitting comfortably in a modern farmhouse scheme. Our 9 shaker doors from £106.50 and 11 cottage doors from £55.99 show the single door equivalents.
Black framed industrial pairs
Slim black frames with a grid of panes, reading as steel without the cost or the cold bridge. We stock over 110 black internal doors.
Glazing options within a pattern
Clear glass is the default. Frosted or reeded glass gives privacy while keeping the light. We list over 110 clear glazed doors, over 20 frosted glazed doors, 7 reeded glazed doors and 5 tinted glazed doors across the range.
Matching the pair to the rest of the house
A French pair is a focal point, so it should relate to the other doors rather than clash with them. Our overview of the most popular internal door styles and our comparison of traditional and modern internal doors both help here.
Materials
Engineered timber with a veneer
The standard construction for a quality modern pair. An engineered core resists warping, which matters enormously on a tall glazed leaf, and the veneer gives the appearance.
Solid oak and oak veneer
Warm, traditional and the most popular timber choice in Britain. Our over 290 internal oak doors start at £87.75, and our guide to whether oak internal doors are worth it weighs up the cost.
White primed
Supplied ready to paint, or fully finished from the factory. Primed is the most forgiving finish for a pair, because you can touch in the meeting stiles after fitting. We list over 80 white primed internal doors from £30.84.
Walnut
Darker and more dramatic, and it works particularly well with a large single pane. Our over 30 walnut internal doors and our comparison of oak and walnut doors cover the choice.
Hardwood for external use
An external pair in hardwood needs regular maintenance but can be repaired indefinitely. Our notes on caring for a wooden front door apply equally to a garden facing pair.
Composite and uPVC for external use
Lower maintenance, better sealed as supplied, and generally the pragmatic choice for a rear garden opening. Our 18 composite external doors start at £725.00, and our grey composite door guide covers the finishes.
Fully finished versus unfinished
A fully finished pair arrives ready to hang. An unfinished pair must be sealed on all six faces, including the top and bottom edges, before it goes in. We stock over 350 fully finished internal doors and over 80 unfinished internal doors, and our guide to pre-finished, unfinished and primed doors explains why that matters more on a glazed pair.
Why finishing all edges matters more on a pair
A pair has four long vertical edges rather than two, and the meeting stiles are the ones that show any movement first. An unsealed meeting stile is the most common reason a pair starts to bind in winter.
French door sizes in the UK
Pair width is quoted as the overall width
This trips people up constantly. A 1219mm pair is two leaves that together measure 1219mm, so each leaf is roughly 610mm. It is not two 1219mm doors.
Standard imperial pair widths
Our pairs come in 914mm, 1067mm, 1168mm, 1219mm, 1371mm and 1524mm overall, which correspond to 36, 42, 46, 48, 54 and 60 inches. All are 1981mm high, the standard UK imperial door height.
Which pair width suits which opening
A 1219mm pair gives two 610mm leaves, which is comfortable for a through lounge. A 1524mm pair gives two 762mm leaves, which is the same width as a normal single door each side and feels generous.
Do not go too narrow
A 914mm pair means two leaves of roughly 457mm each. That is a very narrow leaf, and while it can look charming in a cottage it is awkward to walk through with anything in your hands.
Height and headroom
1981mm is the standard height. If your existing opening was made for a 2040mm metric door, the lining will need adjusting rather than the door.
Measuring the opening properly
Measure the structural opening width and height in at least three places each, and check the diagonals. On a pair, an out of square opening shows up immediately at the central meeting joint. Our step by step guide on how to measure a door covers the method.
Allowing for the lining and the gaps
You need the lining thickness on both sides, a clearance gap at each jamb, a gap at the head and a gap at the meeting stiles. Work backwards from the structural opening to the door size, never forwards from the door.
Trimming allowance on a glazed pair
A glazed leaf has far less solid timber to trim than a solid door, and the stiles are narrow. Do not assume you can take 10mm off a glazed pair. Check the manufacturer allowance before you order, and see our notes on planing a door.
If your opening does not match a standard pair
Widening or narrowing a structural opening is building work and may need structural advice. A room divider with fixed side panels is often the easier way to fill a non standard width.
Regulations, glazing and safety
Glass at low level needs to be safety glass
Glazing in and around doors, and glazing at low level generally, is expected to be safety glass such as toughened or laminated. Every glazed door we supply uses safety glass in the relevant positions, but if you are reglazing an existing pair, do not fit ordinary annealed glass.
Manifestation on large panes
Large areas of clear glass at eye level in a house are less of a concern than in a commercial building, but a full height single pane pair in a busy hallway is worth marking in some way, whether that is a glazing bar, a manifestation strip or simply a piece of furniture that prevents a straight run at it.
External pairs and thermal performance
Replacing an external door in England or Wales is generally notifiable work with thermal performance expectations attached. Requirements differ between England, Wales, Scotland and Northern Ireland, and between new build and replacement. Confirm what applies to your project with your local building control body before you order.
External pairs and escape
Where a door forms part of an escape route, how it opens and how it is secured matters. A double cylinder deadlock that needs a key from the inside is a poor idea on an escape route.
French doors are not fire doors
A glazed pair cannot be assumed to have any fire resistance. If the opening you are filling separates a stairwell, an integral garage, a loft conversion route or a flat entrance, you may need a fire door instead. We stock over 240 fire doors from £87.39, including over 150 FD30 fire doors, 8 FD60 fire doors and over 50 glazed fire doors where you need both light and protection.
When a fire rated pair is the honest answer
Our overview of what fire doors are and where they are needed is the place to start, and our notes on fire door materials explain the construction. A fire door is a certified assembly, so the leaf, frame, hinges, seals, latch and glazing all have to match the certification. Confirm anything specific with your local building control body or a fire risk assessor.
Listed buildings and conservation areas
Listed building consent, conservation area rules or an Article 4 direction may restrict changing doors or altering an opening, particularly on a front elevation. Ask your local planning authority before you commit.
Security glazing for an external pair
Laminated glass in the outer pane makes forced entry through the glass considerably harder, and it is worth specifying on a ground floor garden facing pair that is out of sight of the street.
The hardware a French door pair needs
Hinges: three pairs per leaf on a glazed door
A tall glazed leaf is heavy and the load is concentrated at the stiles. Three hinges per leaf is the sensible minimum. We list over 350 door hinge products, with over 20 butt hinges from £5.61 and over 40 concealed hinges. Our guide on where to fit door hinges covers positioning.
Flush bolts for the passive leaf
The leaf you do not use daily is secured top and bottom with flush bolts let into the meeting stile. Without them the pair will rattle and the latch will have nothing solid to close against.
Latch or lock for the active leaf
The active leaf latches into the passive leaf rather than into the frame, which means the latch and the strike both sit in door edges. Our over 720 locks and latches start at £1.92.
Handles, and how many you need
A pair needs handles on both faces of both leaves if both leaves are used, which is four handles. Budget accordingly. We stock over 2,500 door handle products, over 280 handle packs from £8.99, over 210 handles on backplate and over 280 pull handle products.
Deadlocks on an external pair
An external pair generally uses a multipoint lock in the active leaf and shoot bolts in the passive leaf. We list 3 deadlocks for the simpler cases.
Door stops on both leaves
A glazed leaf swinging into a wall is an expensive accident. Fit a stop for each leaf. Our over 30 door stops start at £10.88, with 43 further stop designs in our door stop styles listing.
Astragal for a flush pair
If the pair is not rebated, a planted astragal moulding on the meeting stile closes the central joint. Our rebated pairs do not need one.
Finish consistency across the pair
Four handles, six hinges and a flush bolt set all in the same finish is what makes a pair look deliberate. Mixing satin nickel hinges with chrome handles is the most common giveaway of a rushed job. Our door handles guide covers finish selection, and our notes on brass handle care and fixing a loose door handle cover the aftercare.
Hardware suppliers we carry
We stock over 1,400 Carlisle Brass products, over 840 Atlantic UK hardware products and over 150 Zoo Hardware products within a total of over 2,900 door hardware products.
Advantages and drawbacks
Light without losing the wall
The single strongest argument for an internal pair. A dark hallway or a north facing back room borrows daylight from the room beyond while still having a door.
Symmetry
A pair centres itself in an opening in a way a single door never can. In a room with a chimney breast or a bay, that symmetry does a lot of work.
Flexible separation
Open for a party, closed for a film, one leaf open for everyday use. That flexibility is the practical reason people who fit them rarely regret it.
Acoustic separation is limited
A glazed pair with a central joint will never be quiet. If sound is the priority, a solid core single door is far better. Our comparison of hollow core and solid core internal doors explains why mass matters.
Swing space
Two leaves need two arcs of clear floor. In a small room the furniture layout has to be planned around them, and that is not always possible.
More hardware, more cost, more to adjust
Four handles, six hinges and flush bolts on both leaves. Every one of those is a fixing that can work loose.
Cleaning
A multi pane pair has a lot of glazing bars. A single pane pair has a lot of fingerprints. Neither is a reason not to fit them, but both are worth knowing.
Privacy
Clear glass gives none. Frosted or reeded glazing solves it without losing light, which is why we carry over 20 frosted glazed doors and 7 reeded glazed doors.
Heat zoning
A closed pair does slow heat movement between rooms, but a single glazed internal pair is not an insulating element. Do not expect it to behave like a wall.
Installation and fitting
Check the opening is square before anything else
Measure both diagonals. On a single door a few millimetres out is absorbed at the latch. On a pair it shows as a tapering gap down the middle, which nothing can hide.
Fit and plumb the lining first
The lining or frame is what everything else references. Get it plumb, square and packed solidly before a leaf goes near it. We list over 30 internal frames and linings and 2 external frames.
Hang the passive leaf first
Fit and bolt the passive leaf, then hang the active leaf against it. Working the other way round means adjusting the active leaf twice.
Set the meeting gap deliberately
A rebated pair needs a consistent small gap at the rebate. Too tight and it binds in damp weather. Too loose and you see daylight down the middle.
Support the leaf while hanging
A glazed leaf is heavy, awkward and expensive. Two people and a pair of wedges under the bottom edge, every time.
Do not force a leaf that binds
Find out where it is touching with a strip of paper before you plane anything. On a glazed door the stiles are narrow and there is very little to remove. Our guides on planing a door and doors that swell and stick cover the diagnosis.
Seal all edges before hanging an unfinished pair
Top, bottom and all four vertical edges, before the leaves go in. Our guides to door finishes and internal door finishes cover the products.
Architrave last
Fit the architrave once the leaves swing correctly, not before. Our guide to door architraves covers the profiles and we stock 16 architrave products.
Flooring under a pair
A pair sits over a wide threshold, so the floor level and the transition matter more than under a single door. Our guides to engineered oak flooring, Karndean flooring and herringbone flooring cover the options, and we stock 12 vinyl flooring products, 6 Karndean Knight Tile ranges from £33.40 per square metre and 5 Karndean Da Vinci ranges from £50.06 per square metre.
When to pay a joiner
Hanging a pair well is genuinely harder than hanging a single door, and the consequences of getting it wrong are visible for years. Our notes on what it costs to fit an internal door set out how fitting is usually priced.
Working at height on an external pair
Anything above single storey height should be left to a professional with proper access equipment rather than tackled off a ladder.
Maintenance
Check the flush bolts twice a year
They take the whole load of the passive leaf. A flush bolt that no longer engages fully is why a pair starts to rattle.
Retighten the hinges annually
Six hinges on a heavy glazed pair will all loosen slightly in the first year. Ten minutes with a screwdriver saves a dropped leaf.
Keep the meeting stiles clean and waxed
A trace of candle wax or a dry lubricant on the rebate keeps the pair closing sweetly through a damp winter.
Clean the glass with the right thing
A microfibre cloth and warm water. Ammonia based cleaners attack some frame finishes and any putty or sealant around the glazing beads.
Do not use silicone spray on the leaf faces
It transfers to hands and then to walls, and it makes later repainting difficult.
Watch the meeting joint through the seasons
If the gap closes up in winter and opens in summer, the pair is telling you the doors were not sealed on all edges. Deal with it before it binds properly.
External pairs need annual attention
Check the weather seals, the drainage slots in the threshold, the finish on the bottom rail and the multipoint lock alignment. Our notes on maintaining a wooden front door cover the routine.
Repainting a pair
Take the leaves off, lay them flat and paint them properly. Painting a glazed pair in situ is how you end up with paint on the glass and a latch that sticks. Our guide to painting an interior door covers the method, and maintaining painted doors covers the upkeep.
Oiled and waxed finishes
Oiled oak needs recoating when water no longer beads on it. If you are using oil, lay the used cloths out flat outdoors to dry, because oil soaked cloths bundled up can self heat and ignite. Our guide to cleaning and maintaining oak doors covers the schedule.
French doors room by room
Through lounge
The classic application. A pair in the original opening between the front and back reception rooms, giving one big room when open and two usable rooms when closed.
Kitchen to dining room
A pair here contains cooking smells and noise while keeping the cook in touch with the table. Frosted glazing is worth considering if the kitchen is not always tidy.
Hallway to living room
A glazed pair borrows light into a dark hall. If the hall is the only route to the stairs, check whether the opening has any fire separation function first.
Home office
A pair gives you a door you can shut for calls while still feeling connected to the house. Acoustic separation is limited, so manage expectations.
Conservatory or garden room
A pair between the house and a conservatory helps enormously with heat, because a conservatory is far hotter in summer and colder in winter than the rest of the house. Our notes on conservatory flooring options cover the same problem at floor level.
Master bedroom to en suite or dressing room
Elegant, but use frosted or reeded glazing rather than clear.
Living room to garden
This is an external application and needs an external specification, not an internal pair. Our over 30 glazed external doors start at £274.81.
Utility or boot room
A half glazed pair with a solid lower panel copes far better with muddy boots and dogs than a fully glazed one. See our notes on dogs scratching doors.
Landing to a loft room
Loft conversions frequently have fire separation requirements on the escape route. A glazed pair is unlikely to be appropriate. Speak to your local building control body before deciding.
How to choose the right French doors
Start with internal or external
This decides thickness, glazing, sealing and security in one step. Everything else is secondary.
Measure the structural opening, then pick the pair width
Work from the opening back to the door, allowing for the lining and the gaps. Our measuring guide sets out the sequence.
Decide the leaf width you want to live with
Divide the pair width by two. If the answer is under 500mm, consider a wider pair or a single door plus a fixed glazed panel.
Choose the pattern before the finish
Pattern 10, single pane, Georgian or half glazed. The pattern determines the character far more than the shade does.
Choose the glazing for the room
Clear where you want the light and the view, frosted or reeded where you want the light without the view.
Choose fully finished unless you have a reason not to
On a pair, factory finishing removes the single most common failure point, which is unsealed edges. Our guide to pre-finished, unfinished and primed doors weighs it up.
Budget the hardware at the same time
Four handles, six hinges, a latch, flush bolts and two door stops. It is not a large sum, but it is not nothing, and leaving it to the end is how projects stall.
Check the fire and regulatory position early
If there is any chance the opening has a fire separation or escape function, find out before you order. Our overview of how to choose the right door for your home works through the sequence.
Consider whether a divider suits the opening better
Above about 1.5m of opening width, a room divider with fixed side panels usually looks better and costs less than trying to force a very wide pair.
Frequently asked questions
What are French doors?
A matched pair of glazed doors that meet in the middle and open from the centre, with no fixed mullion between them. They can be internal or external.
What is the difference between French doors and patio doors?
French doors are a hinged pair opening from the centre. Patio doors, in common British usage, are sliding doors where one leaf passes behind another. Bi-folds are a third option that folds and stacks.
How wide are French doors?
Our pairs come in overall widths of 914mm, 1067mm, 1168mm, 1219mm, 1371mm and 1524mm, all at 1981mm high. Remember that the quoted width is for the pair, not for each leaf.
How much do French doors cost?
Our internal rebated pairs are £407.44 for the Mexicano Pattern 10 with clear glass, £527.50 for the fully finished Vancouver Pattern 10, and £570.42 for the fully finished Coventry, rising to £586.25 in the two narrowest sizes. Frames, hinges, handles and bolts are extra.
Can French doors be used internally?
Yes, and that is what all three of our pairs are designed for. Internal pairs are 35mm thick and single glazed. They must not be used in an external opening.
Do French doors need safety glass?
Glazing in and around doors and at low level is expected to be safety glass such as toughened or laminated. All the glazed doors we supply use safety glass in those positions. Never reglaze with ordinary annealed glass.
Are French doors secure?
An external pair with a multipoint lock, shoot bolts on the passive leaf and laminated outer glazing is a sound arrangement. An internal pair is not a security element and is not intended to be.
Do French doors let in draughts?
A rebated pair with the meeting stiles lapped closes far better than a flush pair. Draughts around a pair usually come from an out of square opening or a lining that was not sealed to the wall. Our guide to draughty doors works through the causes.
Which way should French doors open?
Internally they usually open into the larger of the two rooms so the leaves have somewhere to go. Externally, opening outwards saves internal floor space but is more exposed to weather. Check any escape route implications first.
Do I need a lining or a frame?
Internal pairs go into a lining. External pairs go into a frame with a threshold and weather seals. They are not interchangeable.
Can I fit French doors myself?
It is a considerably harder job than a single door because the pair has to be square to itself as well as to the opening. If you have not hung a door before, a pair is not the place to start.
Can French doors be fire rated?
A conventional glazed pair should not be assumed to have any fire resistance. Where you need both light and fire protection, look at a purpose made glazed fire door. We stock over 50 glazed fire doors, and requirements should be confirmed with your local building control body or a fire risk assessor.
How many hinges does each leaf need?
Three per leaf on a tall glazed door, so six for the pair. Two hinges on a heavy glazed leaf will drop.
Do both leaves need handles?
If both leaves are used, yes, on both faces, which is four handles in total. If the passive leaf is only released occasionally, you can fit flush bolts and leave it without a handle.
What is a rebated pair?
The meeting stiles are machined so one leaf laps over the other, closing the central joint. All three of our pairs are rebated, which is why they seal better than a flush pair.

Still not sure?
If you have measured the opening and are not sure which pair width fits, or whether a pair or a room divider suits the space better, get in touch with our team with the structural opening dimensions. Working out the pair width and the lining allowance before you order is far easier than discovering the problem when the doors arrive.
The parts a pair needs that a single door does not
A pair has a passive leaf, and that leaf has to be held top and bottom by flush bolts so the lock has something solid to engage into. If you would rather build the pair from two single leaves in a finish that is not sold as a factory pair, a rebate kit from pair makers is the way to do it. And where the opening is wide but there is not enough swing space for two moving leaves, one door plus a fixed panel from internal side panels fills the width without the clearance problem.
Product counts, sizes and prices shown here are correct at the time of writing and are subject to change. Building regulation, glazing, escape and fire requirements vary between England, Wales, Scotland and Northern Ireland and depend on the property, its use and whether the work is new build or replacement. Confirm anything specific with your local building control body, a fire risk assessor or another competent professional, and check listed building or conservation area restrictions with your local planning authority.
