Which flooring material for attic space

[camaro1969]

Hello!
In my garage attic, there will be a storage area and hobby room.
There will be an external staircase on the gable.

I'm considering laying chipboard flooring, but since snow and slush might be brought in, perhaps the chipboard won't withstand it?

Would it be better to lay tongue and groove planks as flooring? Maybe it handles water better?

The trusses are mounted on cc600, like regular floor joists

Should it be insulated/heated?

Particleboard does not tolerate water. Solid wood is much better.

The hobby room should be heated in the future, but the storage room should be cold. But I want to use the same flooring throughout.... Is råspont the way to go then?

 

[camaro1969]

So, raw board then? Or are there other options?

Depends on how much you want to spend. Råspont is fine if it's for a storage shed. Or untreated wood equivalent to decking 34x145, for a bit more stability if you're going to store heavy items that you'll pull in and out of the storage often.

How much snow and slush will come in? The wood chipboard can withstand a little water. You can also paint it, making it even more durable.

I have laid floors both from chipboard and rough boards, and I think the chipboard became a much better floor.

The temperature changes a lot in an attic, as does the moisture content of the wood. The rough boards move so much that they separate in some places.

But doesn't tongue and groove lumber become more stable than decking even though it is thicker?

It's just snow and slush that come in with the shoes... About the same as in a regular hallway but much less often...

Then you could paint a bit inside the door, or lay some kind of mat... Or why not a cheap laminate floor?

No idea. Maybe. I just suggested an alternative to ts...

That sounds like a good idea.

I think Byggmax has a "furugolv ekonomi" that should work.

 

[camaro1969]

summa summarum, golvspån!

 

[pelpet]

Link to the byggmax floor above. In reality 100-120 SEK/sqm plus labor.

Moisture resistant floor chipboard might also work but is more expensive, costing 150 SEK/sqm compared to regular floor chipboard for 90 SEK/sqm.

Råspont is around 60-75 SEK/sqm.

I would choose the furugolv. A bit more work than chipboard but still a proper floor.

 

[camaro1969]

Do you mean that you can lay the pine floor directly on the rafters? It felt a bit weak for that... 15mm.??

 

[pelpet]

Yes, that was the idea. But it might be a bit too much bounce if you have cc 120.
