Ideal Applications
Bi-fold doors fold back on themselves, reclaiming floor space that a conventional swing door would occupy. This makes them a practical choice for:
- Bathrooms and en-suites
- Built-in wardrobes and walk-in closets
- Pantry and linen cupboards
- Utility rooms and laundry alcoves
- Room dividers in open-plan layouts
Why MDF for Interior Doors?
MDF (medium-density fibreboard) provides a smooth, grain-free surface that accepts paint evenly without the raised grain common on timber doors. Hollow-core construction keeps the door lightweight — reducing stress on bi-fold hardware — while the MDF facing ensures a flat, consistent finish.
How Bi-Fold Doors Work
These doors operate on a simple hinge-based system — no track required. The two leaves are joined to each other using sinkless hinges (sold separately). There are two common configurations:
-
Standard configuration: One leaf is hinged to the door frame; the second leaf is hinged to the first. When opened, both leaves fold together against one side of the frame.
-
Centre-meeting configuration: Each leaf is hinged to the opposite side of the door frame and the two leaves meet in the middle, folding inward when opened.
Sinkless hinges allow the hinge barrel to sit flush within the door edge, giving a neat finish without visible hardware on the face of the door.
Installation Notes
- Supplied as two separate door leaves — sinkless hinges and handles are not included
- No bi-fold track is required; the doors operate on hinges only
- Prime and paint all six faces (including top and bottom edges) before installation to prevent moisture absorption
- Ensure the door frame is plumb and square before fitting
- Lead time: approximately 5–7 working days
Frequently Asked Questions
What size door frame does this bi-fold pair fit?
This pair is designed for a standard 813 mm wide × 2032 mm high interior door frame. Each door leaf measures 406 mm × 2032 mm.
Does this bi-fold door come with hardware?
No. Sinkless hinges and handles are sold separately. No bi-fold track is needed — the leaves are simply hinged to the frame and to each other.
How are the two door leaves connected?
The leaves are joined using sinkless hinges. In the standard configuration, one leaf is hinged to the door frame and the second leaf is hinged to the first. Alternatively, each leaf can be hinged to opposite sides of the frame so they meet in the middle.
Can I paint these MDF bi-fold doors?
Yes — they are fully paint-ready. Apply a primer coat followed by your chosen paint colour. Prime and paint all six faces, including the top and bottom edges, before installation to prevent moisture absorption.
Are these doors suitable for bathrooms?
Yes. These bi-fold doors are commonly used in bathrooms and en-suites. Because they fold flat against the wall when open, they are ideal where swing clearance is limited. Ensure all edges are properly primed and sealed before installation.
What is the lead time for this product?
Approximately 5–7 working days from order confirmation.
Are these doors rebated?
No. These are non-rebated door leaves.
