Air hooks for Radon membrane

[flanagaj]

I was given the following schematic diagram by St Goblain in relation to their suggested approach for a Radon membrane.  Just wondering whether anyone know how you go about suspending insulation in the cavity with using wall ties?

Visqueen are also showing a similar detail of insulation just suspended in thin air directly below the cavity tray.

From experience this wouldn’t actually be hanging like that below the tray. That bit isn’t really their bag so they won’t pay much credence to it. I used Kingspan green guard full fill below DPC and PIR full fill above. The thermal bridge in the blockwork was dealt with by marmox blocks. 

 

 

The detail on the left, is that a tanking product running up to/under the tray? Assume so as EGL is above IGL

I sorted the typo, sorry, so now you look loopy. Lol.

Be interesting to see the as-built version of the drawings.  That is a lot of different products being applied at the substructure level.  The insulation could be held in place with wall ties, although you could just use blown beads.
