mck75 Posted January 1, 2008 Report Share Posted January 1, 2008 I have been lurking in this forum for a couple of weeks, trying to learn about spa chemistry, etc. Our new spa will be arriving in a couple of weeks and we are preparing the area. A friend recommended putting down a layer of mylar under the spa to insulate . Does this sound plausible? Quote Link to comment Share on other sites More sharing options...

A friend recommended putting down a layer of mylar under the spa to insulate . Does this sound plausible? Happy New Year, here's a bump to the top >BuMp< Sounds like a passing thought through a helpful friends (egg?)noggin? The spa bottoms I have seen are semi-permeable. It's probably more important for it to be able to dry under there than it is to have a piece of mylar trapping moisture. That's why they wrap your house with Tyvek fabric and not Mylar. The added conduction from the damp mylar might be worse that any blocked convection from it's reflectivity... other wise all hot tub bottoms would have mylar. Now the side panels may be another story! ...or another thread. Do a search on the forum for "mylar" or just "Insulation" for more in-depth technical analysis Quote Link to comment Share on other sites More sharing options...
mck75 Posted January 3, 2008 Author Report Share Posted January 3, 2008 You bring up a good point. I hadn't thought about condensation. I guess I'll ask the dealer before he delivers the tub. Thanks Quote Link to comment Share on other sites More sharing options...
