60mm batten for render board

[Ryan Bazeley]

I was going going to fix 12.5mm Knauf Exterior Aquapanel to my SIPS via 25mm x 50mm battens, reading the specification information from Knauf they insist on a minimum 60mm fixing face? Does anyone who has done this know if I should fit bigger battens or will it be okay? TIA

50 is fine As long as your setting out is neat

Thanks, I suppose it doesn’t hurt to double up if needed?

Best to use the same batten where the boards join.

I'd be ok with the 50mm too if you're neat but is the 25mm a bit light? It will have a fair amount of screws in it. Screws fixing the batten to the structure and then the panel to the batten which are doubled in number at a joint. Very easy to split. Would you go 50x35mm?

Hi, thanks for your comments.

 

25 x 50 battens are what’s specified by Kingspan so should be okay. I think?

@Ryan Bazeley what did you use in the end? I'm just trying to get battens did you use rough sawn or c16?
