ᐅ Installing Tongue-and-Groove Boards in the Attic – Tips

So, I need to start addressing this topic. The tongue-and-groove boards have been stored in the attic since the shell was completed. I am currently considering how to approach this properly.

The initial plan was to install the tongue-and-groove boards from gable to gable, laid perpendicular to the (purlin?) beams of the roof structure (which you essentially walk on, going from eaves to eaves). However, this would mean the tongue-and-groove boards would be directly on top of the insulation placed between the beams, which raises concerns regarding air circulation.

A while ago, I received advice to raise the boards. Now, to avoid adding multiple (unnecessary) layers and increasing the height too much, I am thinking of installing battens lengthwise from gable to gable instead of laying the tongue-and-groove boards lengthwise. What spacing should I use between the battens? Then, the tongue-and-groove boards would be rotated and laid on the battens, this time running from eaves to eaves.

Since the boards will need to be cut on site, is it a problem if the cuttings—mainly fine dust from cutting—fall onto the insulation? How can this be prevented?

Thanks for your feedback!

PS:
If time is really critical, you need to borrow a pneumatic nailer and a miter saw with laser guide. That’s how the professionals do it. I had wood plank floors in two apartments, and they were always nailed, never screwed down 😉
And in some spots, the floor was so springy that sometimes I thought if I jumped, I’d end up sitting on the couch with the neighbor below me.

Transporting 5 meters (16 feet) is the least of the problems; it’s easy to manage with a trailer. However, it doesn’t matter if the size means you can’t get it through the house or the folding staircase. In general, planning to save labor is an advantage. Everything always takes much longer than expected, and it’s not just about joining the pieces, but also cutting them beforehand and working with multiple sizes at the same time.

I would definitely recommend screwing the boards together; eventually, you might appreciate being able to open them without damage. The battens can also be nailed. Personally, I’m not a big fan of manual nailing, as your hand quickly gets tired.

It's a pity you used visible screws. There are special decking screws designed to be installed concealed.

Well, it could be worse. It’s "just" an attic.

Here is the finished final product.

I would tighten the protruding screw heads a bit more. You tend to catch on things like that when carrying a heavy box and can’t see where you’re going.
But it looks very good overall—I didn’t put in nearly that much effort 😀
