Insulates well
We found this to be easy to cut and fit to the hot tub, it stays in place while the top is closed and the jets cycling, I was hoping that this would cut my electricity usage a bit which I am sure it will, (had lot of company for a week and the hot tub was in use daily). One indication was the snow on top of the cover, it did not melt off for several days which is a huge improvement.
They do get brittle after a few years or so, but the cost is about half of what our local supplier’s sale price is. Excellent quality.
what a difference....after installing the spa blanket - the problem was fixed....temp back to 111 degrees then after adjustment...back down to 104-105. perfect. And the temp outside is 30degrees.
Once it was delivered, I found out due to the self-cleaning option on my spa, having this cover floating in it (self cleans at 6 am) may damage the unit and void my warranty. I will say, it looked solid and good quality. Easy return...except for FedEx delaying Sending my shipping label for almost a week!!
