Dri Therm Cavity Slab 32 Installation

[Marlz05]

Hi all,

 

Hoping someone here can help, I am building a house and have used Dri Therm Cavity Slab 32 insulation.  Does anyone know if both faces of the slab are coated for water resistance? Is there a specific face meant to face the exterior wall or does it not matter? I can’t find any information on this online at all.

 

Be grateful for any replies.

 

Thanks 😊

Either way round is fine.
