Internal folding French doors are a space-saving variation of traditional French doors that fold back on themselves and sit flat against the wall when opened. Unlike standard hinged French doors, they use multiple panels to create a wide opening while maintaining a classic look. They’re ideal for maximising space, improving light flow between rooms, and creating flexible open-plan living areas.

No, folding french doors don't have a track. They use special hinges that allow them to fold back flat against the wall.

Unlike many of our competitors, our Heritage range of black internal doors are factory finished with a high quality matt black finish. This means there's absolutely no painting or prep to do, you can install them straight away.

Should you need to match the supplied black finish, it's RAL 9011 in a low sheen / eggshell finish.

Many of our internal doors can be trimmed in both width and height to fit your opening. The amount of trimming allowed depends on the specific range, so it’s best to check the trimming details in the technical information section on the product page for the doors you’re interested in.

Installing an internal single door can be a straightforward project for experienced DIYers, but larger doors such as French doors and bi-fold doors are more complicated and may benefit from an experienced tradesperson. Before ordering, it's important to accurately measure your opening to ensure you choose the correct size. All Aspire Doors products are supplied with fitting instructions, although many customers choose to use a professional installer to ensure the best final result.
