There are many reasons to choose internal bifold doors for a property renovation project. They’re an excellent solution for dividing up a room, creating separate zones when required such as working from home. In this article, we explain all you need to know to buy internal bifold doors using our slimline Cortizo system.

Why Cortizo are ideal internal bifold doors

The market-leading slim profile dimensions make Cortizo suitable for projects needing internal doors because they don’t come with the bulk of other brands. In fact, you’ll find Cortizo doors slimmer than Origin OB72, Aluk folding sliding doors, Smart Systems Visofold 1000, Senior Systems and others.

Therefore, correctly configured, our trade supply bifold doors stack neatly together open, taking up less space. When closed, the slim sightlines give larger glass sizes and slimmer visible frames.

Being internal, you don’t need the full weathered threshold of exterior-quality doors. We provide two solutions, both with a minimum step and our AYPC.BF73.0104 Low Threshold Sill even creating a fully flush arrangement when sunk into the floor.

How to measure internal doors.

1. Take the tight opening size of the door aperture and reduce this by 10-12mm.
2. You now have the manufacturing size of the doors that we need to make them for you.
3. It’s recommended you measure the width and height across several points to make sure the opening is square and consistent in size.
4. Then you can measure from corner to corner, another check to make sure the opening is square. If not you can make some small adjustments.
