Pour in foam as insulation?
« on: August 04, 2020, 10:27:26 pm »
Looking for a cheaper alternative to the spray in expanding polyurethane foam to insulate my spa. Ive found the pour in variety to be much cheaper, though it will require a bit of work to make it insulate the whole spa.

Ive only seen one other person do this on youtube but cannot find the video at the moment.

wanted to reach out to yall and see if this is a bad idea before proceeding.

R-32 insulation and then put a wrap of reflective foil to hold it all in.  Will make life a lot easier should anything happen to the plumbing in the future and will be just as efficient as other insulations.
