I want to board out loft, for simple storage - nothing fancy.
The roof a-frames are, more or less, like these -
I intend to put my boards on top of the horizontal part of the a frame. I am aware that this means that the weight will be supported by this timber, and not the walls, which im not that pleased about, but i have no other option.
Because of this, id like to try and keep the mass of my new "floor" as low as possible. Again, this is only for storage. Static load, and about the heaviest individual item that im likley to put up there would be a landrover cylinder head, and i can try and arrange that kind of stuff closer to the walls.
...but, of course, items in storage always add up!
Anyhow, i want to run timbers between the horizontal rails, parallel to the pitch. The span between the rails is 2 mtrs. Ill then board, perpendicular to this, with standard chip board. I cant remember if i purchased 18mm or 22 - the latter, i think.
I think that the calcs say 5x2 (125mm x 47mm in metric) but a) i want to keep the weight down, and b) my local options are 125mm in regular tanalised, but 100mm in C16/C24
Im in two minds. I dont know how graded really compares to standard. Which would you use on 600 centers over a 2m span?
