Why would they be soaked, they are inside. If they are wet you have bigger issues.

 

Why a SAP fail?

 

think we talking cross purposes. I'm talking about the external door, the marmox goes on the external skin under the door frame hence they are exposed to outside are buried underground and can get wet.

 

Thermalite blocks  are a SAP fail for any cold bridge elimination function as they aid cold bridging not prevent it.

 

Think  about it, otherwise no one would ever use the the expensive marmox would they if you could just throw on a cheap thermo block and call it job done. Thats how internal skins have been built for decades and its crap for cold bridging.
