Anyone installed pine or spruce flooring in an uninsulated conservatory?

I know it's not the best idea to install wooden floors when the sunroom is uninsulated, but it would be interesting to hear from those of you who have done this anyway—how you did it and how it has worked over time? Is it possible to minimize the risk of cracks, for example?

No experience with that specifically, but I want to advocate for putting plenty of insulation under the floor. It makes a big difference in comfort during the fall and spring by avoiding drafts and ground cold. Dad and his neighbor have similar conservatories, but Dad threw in 40 cm of leftover insulation under the floor. They sit outside with plenty of clothes this time of year, while Dad doesn't even put on slippers.

No experience with that, but I want to emphasize putting a proper amount of insulation under the floor. It makes a big difference in the fall and spring for comfort to avoid drafts and ground cold. Dad and his neighbor have identical conservatories, but Dad threw in 40 cm of leftover insulation under the floor. They are outside with lots of clothes this time of year, while Dad doesn't even put on slippers.

thank you for the input. Unfortunately not possible in my case since I don't want to tear up the existing floor.

I was thinking of laying the floor directly on top of pressure-treated wood with some form of foam in between as a base.

Solid wood floors have existed long before we started insulating houses the way we do today. For example, our house was originally a summer cottage built in 1958 without insulation and has always been cold until 4 years ago, and it has a solid spruce floor that has been there since it was built.

So I would say just go for it!

I have not installed it in a sunroom. But I have laid flooring in an open shelter. The first attempt was before a roof was installed. It got wet and swelled, making it quite wavy. I screwed it down in its wet state. It now alternates between a tight floor and one with large gaps, even though it doesn't get rained on. So don't lay it as tightly as you would indoors.

Consider some thoughts on ventilation/moisture pressure under the floor...

If it's dry and fresh, it will be fine, but if it's wet and enclosed, it will be a challenge.

It's a wooden beam construction with about cc60 and there are 2-4mm gaps between the boards today. It hasn't seemed wet so it shouldn't be a problem. Sometimes late at night, you can feel it's a bit humid in the conservatory (ground moisture), but there isn't much to be done about that, it should be okay?

Then one should lay foam in between to avoid creaking, right?

I know it's not the best idea to lay wooden flooring when the conservatory is uninsulated, but it would be interesting to hear from those of you who have still done this, how you did it and how it has worked over time? Is it possible to minimize the risk of cracking, for example?

I laid a 45mm thick pine floor and waxed it with linseed oil wax. It's still nice after almost 10 years of use. There are 30 large barrels with plants that are messing around. Just need to sweep it off. It's possible to mop it as well.
