I have a Nahanni Spa by Maax, which I just love. I would like to a little extra insulation on the inside of the cabinet. It is the Thermo-pane style of insulation right now. Just wondering if anyone has done this or has any "Do's and Don'ts", they could share.
Of course, the company says that theirs is the most efficient system out there, but I'm not so sure.
What I am planning on doing is adding 1 1/2" blue styrofoam on the inside of the cabinet and maybe the expanding spray foam in the corners. On the inside of the frame(closer to the tub) I thought of adding that thin reflective insulation. So, the order starting at the tub----- factory sprayed foam, air, reflective, blue stryofoam and then the cabinet.
Any thoughts.
THanks in advance
