Crittall French Doors, Designed Around Your Opening

Crittall French doors bring together the slender steel profiles the brand is known for with the openness of a true French door set. Where a timber or uPVC frame needs bulk to stay rigid, steel holds its shape at a fraction of the width, so more of the opening is given over to glass and less to frame. The result is a door that reads as much like a window as it does a door, letting a room open fully onto a garden, courtyard or terrace.

As a Crittall Specialist Partner, Lightfoot designs, supplies and installs every set to the exact opening it’s built for. We work on period properties where a French door needs to sit comfortably alongside original steel windows, and on new builds where the brief is simply as much glass as the wall will allow. Every project is measured, specified and fitted by our own team, from the first enquiry through to the finished installation.

Heritage, Listed Buildings and Conservation Areas

Steel French doors are a familiar sight in period properties, and for listed buildings and conservation areas they’re often the design that planning officers are most comfortable approving, since the slim profile closely echoes the steel windows the properties were originally built with. Every project is different, and local planning requirements vary, so it’s worth speaking to your local authority early. Our recent restoration in East Sussex shows how a Crittall specification can sit within a heritage property while still meeting a family’s day to day needs.

A Genuine Crittall Specification, Fitted by Lightfoot

Every set we supply is manufactured by Crittall to the same specification used across their residential and commercial range, so you get the material quality, welded steel construction and finish options of a genuine Crittall product. What Lightfoot adds is the local part of the process: taking accurate site measurements, managing the order, and carrying out the installation ourselves rather than handing the job to a third party.

Looking for Inspiration First?

If you’re still deciding how a set would work in your own home, it’s worth browsing our French door design ideas, which walks through glazing bar layouts, colour choices and the difference between opening a room onto a garden and using a set internally. Plenty of people come to us with a rough picture in mind and firm it up once they’ve seen how other projects have handled the same wall.

Getting Your French Doors Installed

Once your order is placed, your doors are manufactured to the exact specification agreed at survey stage. We schedule the installation directly with you and carry out the fitting with our own team, so there’s a single point of contact from the first enquiry through to the finished doors.

Why Choose Steel French Doors

Steel behaves differently to other frame materials, and that difference shows up in how the finished doors look and perform.

Frequently Asked Questions

The questions we're asked most often about Crittall French doors.

Are Crittall French doors thermally efficient?

Steel conducts heat more readily than timber or uPVC on its own, which is why thermally broken frame options exist within the Crittall range. We'll talk you through which frame system suits your project's thermal requirements as part of your quote.

How secure are Crittall French doors?

Every set comes with a multi-point locking system as standard, so the slim steel profile doesn't mean a compromise on security.

Can I choose the colour and finish?

Yes. Crittall French doors are available in the standard RAL and BS colour range, including the black steel finish most associated with the brand, finished in a durable powder coating.

Are Crittall French doors suitable for a listed building?

Steel doors are often specified for listed building and conservation area projects because of how closely they match the profiles of original steel windows and doors. Planning requirements vary by property and by local authority, so we'd always recommend checking with your planning department before committing to a design.

Which frame systems are available for French doors?

Crittall French doors are available across several frame systems, including the Corporate W20, the thermally upgraded W20 TE, and the Corporate MW40, each suited to slightly different performance and budget requirements. We can talk you through which fits your project.

What's involved in ordering Crittall French doors through Lightfoot?

We start with a consultation to understand the opening and the look you're after, then survey the property to take exact measurements. From there we confirm the specification and finish, place the order, and carry out the installation ourselves once the doors are manufactured.
