Concertina Doors

Our Concertina Door Collection

Concertina doors are internal bifolding door sets that collapse neatly to one side, freeing up space while preserving clean sightlines. Their multiple hinged panels run smoothly along an overhead track, stacking elegantly for easy storage.

Designed to fold rather than swing, internal concertina doors provide easy entry and natural light without sacrificing wall or floor space. Also known as slimline doors, concertina doors are a smart choice because they’re suitable for all types of homes.

FAQs About Our Concertina Doors

Discover answers to common questions about our space-saving concertina doors here.

How do folding concertina doors compare to sliding doors?

Concertina doors open fully, folding back panels to give you a wide, unobstructed entry. In contrast, sliding doors are mounted on tracks and usually only open halfway, maintaining floor space but limiting full‑width access.

Are concertina doors durable and easy to maintain?

Yes. Concertina doors are low-maintenance and designed for minimal upkeep.

1. Regularly clean the tracks and hinges. 

2. Apply a silicone-based lubricant a few times a year to keep panels gliding smoothly.

3. Check for loose hardware to tighten.

4. Realign panels if they start sticking. 

5. For glass panels, use a standard glass cleaner.

6. Use a wood polish for wooden systems to keep the finish looking fresh.

Can I install a concertina door myself?

We recommend a professional installation. While we supply quality concertina doors, we don’t offer installation. However, our support for self-installers is captured by our “DIY, Trade, or Bulk” company ethos.
