Insulating basement floor around mechanicals and sump
I’ll be installing an insulated basement floor as shown here (https://www.greenbuildingadvisor.com/article/installing-rigid-foam-concrete-slab), and I was wondering about the mechanical room. I’m assuming it is best to place mechanicals like the water heater on top of the plywood subfloor, but what about the sump pump hole / drain (see attached pics).
Does the insulation run right up to that hole, and that’s it? Or, is there another preferred approach?
Thanks much – Ryan
