Floor in the conservatory

[Nygge72]

I have a question regarding flooring in a sunroom. Today, I have an open/roofed porch on high piers. The floor currently consists of regular floorboards with about 10mm gaps.

My idea is to enclose this porch with glass so it can be used in spring/autumn as well, and I may need to insulate the floor so it doesn't become drafty. But what type of flooring should I use for the best result afterward?

I should have a floor that is proper/without gaps. The floor should be durable since it is a type of rough porch that must be passed to enter/exit the house.

I would greatly appreciate tips on materials for the floor.

Is the porch intended to be heated year-round?

Klinker is a durable floor. Would the floor construction be able to be stiffened enough for it to be installed?

Is the veranda intended to be heated all year round?

Tiles are indeed a durable floor. Would the floor construction be possible to stiffen enough that it could be laid?

No, it will not be heated at all, more than the solar heat. So tiles feel too cold for me.

The problem with wood in an unheated space is that it tends to move and expand when humidity changes.
If you lay a tongue-and-groove (gapless) wooden floor, there's a risk it might buckle when humidity increases.
That's when, for example, a laminate based on a different base than wood is better. But it risks becoming very slippery (especially in winter).

I would have chosen click-type vinyl flooring. It is available in both soft and hard variants. It withstands moisture and is as easy to install as laminate.
