Garage Conversion... Ventilation??

[Jckay21]

Hi all.

Not far off starting a conversion on our garage. Was built approx 18months ago.

Single block skin with render finish. The plan is to stud out inside, rigid insulation board between studs then a sheet of rigid over the face, then batten (service void) then plasterboard. Obviously taping and sealing for vcl etc.

What I'd like to know is what's the best idea for ventilation within the cavity? We have vents ontop of the fascia, underneath the first corse of slates but that's it. Would this suffice? Or is there any ideas? Or do I leave as it it...

As you can see the rear wall is retaining some of the garden at the moment but will be tanked etc once the new drainage line etc is put it. There is no signs of damp inside etc either.

Much appreciated

would be easy to fit and not damage the render.

Okay.

 

Don't these need fitting towards the bottom of the "cavity"?  As the photos show the wall is block plus two corse wide in the bottom?.

 

Thanks for suggestion @TonyT much appreciated

Lift it up to the render or fit a larger pipe onto the vent to extend the length?

[Jckay21]

I think some plastic pipe to extend is the way forward @TonyT

Good stuff

And the top of the wall too.

I was going to install eaves vents at the top. @TonyT

 

Although there is vents under the first corse of slates so thought that would suffice.
