The 70mm aluminium folding sliding door is our most popular system. It offers a modern look coupled with strength and durability. Minimum maintenance is required to keep its looks, and is thermally broken to keep the cold out.

The system comes in a standard colour of white (RAL 9016), but can be coloured to suit your tastes for a little extra.

  • Thermally broken for greater thermal efficiency
  • Heavy duty cleats to make stronger and bigger panels
  • No condensation
  • Resistant to scratching and denting (1.75mm wall)
  • Contemporary appearance
  • Dual colour optional

Built for Strength
We use over size cleats to hold our aluminium panels together to ensure longevity of the joint. The cleat shown on the left of the coin is a competitor’s cleat that was removed from a door panel on a system we replaced. As you can see it is bent out of square.

The experience of using The Folding Sliding Door Company was a pleasure from start to finish. The website was very useful, brimming with tips and videos and the sales staff were genuinely helpful. They guided me through my order and delivered at a date to suit my builder, making sure he had assembly instructions and a technical contact number should he need clarification during the installation. The Folding Sliding Door Company even stayed in contact after the door was fitted and our extension complete! In fact, conversations during these friendly follow-ups aided our garden design. I don’t see The Folding Sliding Door Company as an ordinary supplier; I see them as a friendly, caring manufacturer who makes sure you get the best from your folding door feature. And they guarantee it too...”
