Hi There,
I'm new to this forum. I am building my home soon here in Middle Tennessee area. My question is this. I am building on a full slab foundation. It will have a wrap around porch that is also slab. Will be pouring all in one pour. I do not want to insulate the whole slab. Seems every builder here in Tennessee thinks that is over kill. But they do suggest insulating the perimeter main footer. Every detail I find on the internet has 2 inch foam board insulation on the outside face of the footer all the way up to the top of slab. If I do that... I will see 4 inches of it above my porch slab, not to mention how in the heck do I form this 4" step down transition with this insulation panel in my way? I am using board & Batt siding but that will not cover this insulation. It will set directly on top of it. Do I need to insulate this footer? I will have 10ft depth porch 4" thick slab all the way around the main house slab (covered porch) all pour as one. Advice???
