ᐅ Decision: Double French Patio Door – With Mullion or Without?

Hello everyone,

we are currently facing a decision on whether our double-leaf patio door should have a mullion or not. Until recently, I thought it would be better without one. However, our general contractor convinced me to go with a mullion. The main argument was that the door is safer with a mullion.

What are your thoughts on this? And your experiences?

Best regards,
Alex

Sliding doors don’t slam even with a light breeze.

For a double-leaf patio door, I would never use a post. It’s always in the way. I would choose a mullion (or a stile) so you can easily move larger items through the door, like a drying rack, couch, etc.

Thank you for your opinion. I would choose a sliding door for a large window façade. However, ours is just under two meters (6.5 feet) wide.

We have a French door at 2 meters (6.6 feet) – our builder did not raise any warnings or concerns.

There were no concerns or warnings either. He explained both systems to us and listed the advantages and disadvantages.

What is your experience with stulp (French doors)? How often do you use it (i.e., both door panels fully open)? Is it tricky to open the passive door, or do you perhaps have a handle on each door?

We have a French door; when properly adjusted, there are no issues. The second door leaf is also not a problem, as the lever hidden within the frame is easy to operate. In my opinion, having both doors open is only really necessary for moving furniture, garden parties, or perhaps during the first days of spring. Otherwise, one door leaf is usually sufficient. However, long-term experience is still lacking.
