Do you think the pumps will over heat in the summer? Hot for us is in the upper 80's to low 90's (very low humidity). I live in the mountains so even with highs like that it gets cold at night. Yesterday was upper 70's but last night was mid 30's. We dont use the spa during the day in the summer but the pumps do run for filtering which I have noticed raises the temp significantly. I'm not sure how to address any overheating issues with this type of insulation.

I'm new here, but wanted to contribute to this thread. I have been interested in adding insulation to my spa. I purchased two part spray foam from this company http://www.polytechfoam.com/index.php?page=TWOCOMPSPRAY It was $250 shipped to my door for the 200 board foot kit. That should easily be enough foam to put 2" on the skirt of my spa. The claimed R value is 7.2 per inch. I feel more comfortable with a spray foam than rigid foam because it will fill all voids easily and be seamless. I am not sure when I will have time to install it but will update when I do.
