There are a lot of messages on here saying a lot of things! It might be basic to you with your years of shed building but its new to me so stop being condesending. So should i raise the osb with 25mm battens or not? I notice there was no membrane on your shed diagram

What is wrong with breather location? On a traditional roof breather goes on rafters then battens then tiles. Except in this case its osb instead of tiles? The osb will be covered in felt which i will wrap around the fascia

It will be osb inside, pir insulation enough to leave 50mm void then breather and osb

So should i raise this OSB roof up with some battons then?

I am just doing the one osb skin inside now. I didnt have a larger overhang as the wood was 2.4m so i just went with that to save time and money

Ah good point!

:lol: :lol: :lol:

Its fine i knew the answer as soon as i finshed building it lol, ill just raise the osb with some battons i guess

I guess your going to say that breather membrane is pointless due to it being not able to breath and butted up to osb and i should of raised osb roof? If anything though it serves to stops water if somehow it gets through roof

i do notice there is still some wobble with the frame, will this be rectified once the inner osb is installed which will offer more stability and strength or will i require some diagonal braces of some sort?

You mean reinforced double header etc above where the door will be? Yea i have not built that yet, last bit of framing to do

I am indeed a very nice chap and i don't appreciate sarcastic remarks thrown at me.

I understand the differences i was just wondering about behind the membrane and whether that could be solid, but as Mike stated i guess it cant and it needs a void to breathe and lose fill insulation wouldnt really affect that.

Thank you for the informative post, the 80% rule is interesting i will research that further, regarding your other points i would have put the breather membrane over the osb not under, does breather membrane also require clearance behind? I guess not due to it normally backing onto insulation
