Breeze block garage

Its rendered so moisture should not be an issue not unlike the Kingspan K118 specView attachment 249976

As for:

...although, would the battens need better protection from water ingress, if attached directly to the single skin?

The Kingspan specs recommend backing the battens with DPC



Edit:
Ooops, sorry @noseall , I didn't notice your comment about running DPM behind the battens.

 

[noseall]

it won’t be the same place though. It’ll be trapped behind his insulation.

You trap the DPM behind the battens and insulation. In other words the DPM is against the wall and battens and inso' in front.

Sorry for any misunderstanding

Read my post again and see if you can get where the DPM membrane occurs relative to the damp outside wall. I look forward to hearing that distinctive noise as you slap your own 'ed.

According to your plan the dpm runs 600mm up the wall . against the potentially soaked single block.
what I asked was what happens to the potential water/moisture that will innevitably soak straight through the block regardless of whether its rendered or not.

The 600mm DPM up the wall is merely a lap for the vertical DPM which covers the wall and is trapped behind the battens and Iinsulation.

It's not difficult to grasp.

trap 100mm Celotex and DPM behind 50mm x 25mm battens for the walls.

The water or damp does what it always did and remains in the block.

its not difficult to grasp if youd stated dpm the whole wall in the first place. and still no answer to where the moisture will go.

 

[noseall]

Semantics. You seem to be the only one not grasping the idea.

 

[noseall]

iand still no answer to where the moisture will go.

It need not go anywhere as long as the dry items are protected. Where do you think it goes in any other wall.

 

[Deleted member 292770]

Senantics. You sern to be the only one not grasping the idea.

i get the idea . it’s my job . personally I wouldn’t entertain your idea.

theres no need to pout. Because someone disagrees with your cowboy method, which is frankly idiotic.
trapping moisture behind a plastic sheet with no potential for evap or ventilation .
nonsense.

Stick to plastering boyo. You are clueless.
