Aluminium French doors
Aluminium French doors: a slimmer sightline and more load-bearing capacity per leaf — and with two leaves side by side, that difference counts twice.

Profiles that can do this
Uf, frame depth and sightline come from the profile table. The corner section is the manufacturer's render of exactly this profile: for Aluprof always the same shot — closed corner, close up — and for Gealan the render of the S 9000 NL family. The maximum sash width is on every profile page.

How it works
Sightline and strength with two leaves
An aluminium door with us sits between Uf 0.57 and 1.50 W/m²K, with sightlines from 97 to 128 mm. For French doors that slim sightline is the argument: two leaves side by side means two leaf frames in view, and then every millimetre counts twice.
Door sizes
Aluminium also carries more weight per leaf. On a door that opens and closes every day and holds triple glazing, that's no luxury: a heavy leaf on a light hinge point will drop over time. The profile goes up to 6,000 × 3,000 mm, but a door stays limited to 2,500 mm in height.
MB-86N, MB-Ferroline or MB-79N?
Colour: any RAL, smooth or textured. On French doors, which are seen from inside and out, you can have a different colour on each side. Which combination is possible on your profile, the configurator will tell you.
What you need to measure
Of the aluminium in the row above, one usually drops out for French doors. The MB-Ferroline is made to look like steel and needs 110 mm of frame depth for it at Uf 1.50 — for a door you use every day and that holds triple glazing, that's a looks choice with a price. That leaves the MB-86N if the U-value matters, and the MB-79N if the opening stays under 5,000 × 2,700 mm; at 70 mm it's the shallowest.
Security on French doors
You're already two steps further than where the configurator starts. It first asks what the door is made of and then which profile, and that's exactly what you decide on this page. What it then asks of you is the size and the layout, the glass and the colour. For the size, measure the structural opening at three heights and three widths; the smallest figure is your size. Two things count extra with French doors: the threshold height, because you step over it, and which of the two leaves is the active one — the one with the handle. The other normally stays shut and only opens when you release it.
Cylinder, handle and threshold in the configurator
French doors open onto the garden, which makes security matter more here than almost anywhere else in the house, and aluminium is no disadvantage there. A security class such as RC2 (EN 1627) belongs to the complete element, including hardware and fixing — not to the material of the profile. That's why we don't list an RC class per profile.
Aluminium French doors
On French doors it's the locking parts from step 6 that matter, and on aluminium the slim frame comes into it. Standard locking hardware is fitted; what you add is the cylinder, which comes as a standard one and a heavier class C. Then the handle and the threshold. With two leaves, bear in mind that whatever you hang on the active leaf is in view too: on a 97 mm sightline a handle is a bigger gesture than on a wide frame. Glazing bars and an insect screen are in the list as well — it isn't filtered by element type — but on a door you use every day they're rarely what you're after.
Aluminium French doors with side panels
Aluminium French doors always come with their frame, as one unit, in any RAL colour. The sightline starts at 89 mm, slimmer than uPVC, and with two doors that counts twice.
If you want fixed glass or side panels beside the doors, it becomes an aluminium set. Put it together in the configurator as one quote.

Questions about aluminium French doors
Why aluminium for French doors?
Two reasons: the narrowest combined sightline of frame and leaf we have — 89 mm on the Reynaers CS 77 against 119 mm on the Gealan S 9000 in uPVC — and more load-bearing capacity per leaf. With two door leaves side by side you see that difference in sightline twice.
How tall can aluminium French doors be?
2,500 mm. That's the manufacturing limit for a door, whatever the material. The profile itself goes to 3,000 mm, but then it's a window, not a door.
Which aluminium profile for French doors?
The MB-86N if insulation matters: Uf 0.57 with a 128 mm sightline, up to 6,000 × 3,000 mm. The MB-79N if that doesn't tie you and the opening stays under 5,000 × 2,700 mm — at 70 mm frame depth, the shallowest aluminium we carry. The MB-Ferroline only if the steel look is the goal; it costs you Uf 1.50 against 0.57.
What should I measure before I start?
The structural opening in width and height, each in three places. A door is never taller than 2,500 mm and a leaf never narrower than 600 mm, whatever the material. Look at the floor on both sides too: the threshold is where weathertightness, insulation and threshold height meet, and that's work for your builder or structural engineer.
What does security mean for French doors?
French doors are one of the most accessible elements of a house. That aluminium is stronger than uPVC says nothing on its own about a security class such as RC2: that belongs to the complete element, including the hardware — which is where SKG stars, the Dutch hardware rating, sit — and including the fixing. We supply, we don't install, so discuss the fixing with your installer.
Can I have a heavier cylinder?
Yes. Besides the standard cylinder there's a class C security cylinder in the list, and on request all cylinders can run on the same key. What it isn't: a statement about the security class of the door. That depends on the complete element and on how it's fixed into the wall, and we don't do that part. If you need to demonstrate a class, you need the installer, not just the cylinder.
Can aluminium French doors have side panels?
Fixed glass beside the doors is put together in the configurator as a set. Request a quote and we'll price the whole thing on your size.
