I use the same set up. I made an insulating blanket with air conditioning duct insulation. It works pretty good but I still have to add some heat at least once. I used heavy duty aluminum foil and foil duct tape to make the blanket from two pieces of the insulation.
I do slowly heat my sparge water at about 30 minutes into the mash. Hopefully that adds a little heat to the mash.

I use a sleeping bag, doubled over, and folded up over my BK. Holds temps within 1 degree for 90 minutes. It is heavy, so that probably won't work for larger batches. My last mash was a full volume BIAB batch, strike water was 8 gallons.
