Cable fixings in service void

[OwenF]

I have 25mm deep battens for a service void, with airtight membrane immediately behind.

 

how is everyone fixing cables in the void? Clipping to the batten feels like cables would be at great risk from a rogue PB screw.

 

I agreed using plasterboard boxes with the electrician, to minimise need for box supports etc. but thinking about it, this means more need for cable support until PB is on.

Usually depends on how deep the service void is.

 

Some people fix to the batten. Some people put a thinner piece of timber across the void and fix to that. Some people put a (25mm in your case) piece of timber across the void and run cables through it.

 

The trick is obviously not to go through any airtightness barrier if possible. If a solid barrier (smartply) you can glue your counter battens to it. If not, you'll probably need to use the vertical battens to take the fixings for the horizontal battens.
