18" Wide Foam Insulated Threshold Ideas ?
On my new house build, I'm getting bids on having my footers & walls formed & poured.
Standard practice is to pour the slab out through the doorways to the outside.
This would be a Very bad way to do this with a radiant heated slab in climate zone 5. Lots of heat would be wasted.
I need to come up with an 18" wide threshold. It needs to span the 8" concrete stem wall on outside + 6" of EPS foam & then 4" over the slab on the inside.
It needs to be strong, durable, look good enough.
Ideas?
