New breathable membrane

[Ant1]

I need to choose a new breathable membrane for my roof which is getting re-slated, any advice on efficient membranes?

Permavent Max Membrane is on my list, what do you use?

Horse hair or 1f?
On a serious note klober permo is my preference but I know every tiler has their own.

Thanks guys, is the Klober Permo Forte definitely a breathable membrane? I am asking because I will only at 25mm gap between the insulation and the slates, hence I am required to use a breathable membrane.

 

[datarebal]

Yes it is

Permo air might suit you better

Roof shield is fine. Just not my preferred
