To insulate apron or not
I have a heated garage ( with wood and propane heat) with a slab on grade. I have insulated the perimeter of the garage with 4 inches of foam 2ft in width to prevent the frost from getting under the slab. I want to pour an 8ft apron out the front of the garage, my questions are as follows
1) should I insulate the apron? If so how should it be done?
2) Should I be pinning to the existing slab? And does insulating make a difference if pinning together or not
3) Should there be a thermal break beteeen the new apron and the old slab? Ie 2″ foam against the old garage with the concrete poured up against it?
We just don’t want the new apron to crack or shift too badly. We do have cold winters here. Climate zone 7a
