Lime lath ceiling

[OldieNewbie]

Hi all, 

 

On an old latted ceiling, what would be the distance between the timber lathes? Is the distance the same as what the thickness would be?

 

So if the timbers are 5mm, are they installed 5mm apart?

 

Thanks

Thanks Nod. What would decide the reason for the distance between the laths?

I'm just guessing, but perhaps the maximum size of aggregate in the plaster? A 3mm gap won't let 4mm particles through, but a 6mm gap will.

That makes sense Nick. Thanks for that.
