Sill sealer help please
Is there any benefit/need to put a foam sill sealer under interior bottom plate walls?
*** The question is in regards to a slab on grade foundation.
*Given an important reason for putting a foam sill sealer under the mudsill is for it to act as a capillary break, is it necessary / a good idea to put the foam sill sealer under all of the first floor bottom plates as they are all in contact with the slab?
*Or is it that the perimeter of the slab has a much higher moisture content and therefore only here the foam sill sealer is needed?
*If the perimeter is higher in moisture content levels, does that moisture travel horizontally inwards along/through the slab above any “plastic” membranes placed under the slab?
*If so, does any moisture travelling inwards along the slab dry out and not cause any concern for moisture travelling through the interior pressure treated bottom plates and into the bottom of the untreated studs sitting on them?
