Aluminium Bifold Door Condensation
Discussion
Had some bifold doors fitted 18 months ago and they’ve been great - no issues.
As we started to approach this winter, the frame particularly around the base has started to see heavy levels of condensation. Silicone was applied between the floor tile and door frame, however I’ve pulled it out as the condensation was so heavy the silicone went black!
Picture following the removal of silicone attached.
Does anyone have any recommendations on what can be used between the frame and concrete / tile flooring to stop the cold air from getting in and creating the condensation please?
Thanks!

I suppose even if they are it is no guarantee that condensation will not form, especially along the base of the frame where the air is coldest.
...so probably not much you can do unfortunately beyond the usual 'controls' such as ensuring adequate heating and ventilation. It's one of those things I'm afraid in our modern air sealed and highly insulated homes.
Sorry to answer your specific question, something like Compriband expanding tape inserted into the gap then re pointed with a silicone or polysulphide sealant is pretty much all you can do. It's more likely to be a case of thermal bridging than draughts causing the issue I would have thought.

I have an indoor pool with Ali doors ( ie a harsh environment ).
We get a small amount of condensation on the frame.
At the top of the frame ( where ventilation is poorest ) I put some neoprene tape in white on top ( you can't see it ) which stops much of the top condensation as it is warmer. You could do the same but in your case it would likely be visible.
When it was installed we had some condensation at the bottom and it turned out to be that it was not sealing properly and when that was corrected it solved the issue.
It is annoying that thermally broken frames are not as thermally broken as they should be !
The only other thing you can do is control the indoor humidity by ventilation or increasing the room temp such that it holds more moisture.
