One bad apple spoils the.... ?
I contacted Jeff Sliger of Another Company who makes the spacap.
I said I was interested in his cover but, due to the unique nature of his cap I was a little nervous. I asked him if I could see a copy of his R value testing. Or, was there customer near me that I could ask about it.
His response was that he would not give me any references and "Did you ask any hard cover dealers for customer references? No, because you know from personal experience they don't work." I replied , that I did in fact ask my spa maker for references on a spa cover with a radiant barrier. He gladly gave me a number of them.
I then , again, asked Jeff Sliger for a copy of their R-Value testing. Had he provided it and it verified his claims, I would have purchased it. His claims seem to be very high for just plain air. It contradicts all the information I found on R values for dead air spaces.
Jeff Sliger never replied. Very rude. This ticked me off a bit. At least tell me, NO you're not going to send it. Of course this peaked my curious nature and I did a little searching.
Spacap.com/ Another Company/ Owner Jeff Slinger have an unsatisfactor rating with the Better Business Bureau of Western Washington.

This is my experience with this company. I won't do business with them. Thanks to the forum for a heads up.
