Treated or untreated timber for a loft?

Hiya,

I recently installed loftzone flooring in our loft but in one tricky section, there were two planks bracing 3 of the joists together. I had to remove the one of the to fit the supports for the loftzone system and I replaced it about 2-30cm along using kiln dried untreated timber of a similar size with screws instead of nails as to not disturb the plastboard below.

I'm not even sure if I needed to replace it as the loftzone system should add some bracing anyway. But should I of used treated wood instead?

In the photo, the bottom lighter coloured wood is the new one. Next to the truss is the old one.

Thanks :) I noticed this morning when moving some stuff about up there that all the trusses have stickers on stating they're untreated anyway so if they're not then that little board I replaced shouldn't need to be :LOL:

I'd also add that there shouldn't be any requirement to use treated timber for that purpose - given the amount of untreated wood up there already, if you *did* need to use it, I expect you'd have far bigger problems anyway!

Depending on what the issue was with fitting the last LoftZone support, I've used their intermediate supports in places where the triangles wouldn't fit, but it seems like your job is a good'un anyway!! :)
