did some mroe calling around and found a place that would cut my 9" wide round 8ft insulation peices with a 3" hole on center for the pex.
R of 4.7 per inch. with 9" across, minus 3, 6 split in 1/2, result * 4.7 is R on all sides of pipe. R of 14.1.
Now, i've called a few places that sell the polyurethane pipe and of all the people i asked, i could only get one to give me an answer, he said it's got an R of 13. Dunno how true that is? anyone have an idea?
i called about the pre-made thermopex pipe, and no one will tell me the value.the only reply i get is " it's really good stuff, you can put it in water"
wtf kind of an asnwer is that? doesn't sound very professional if you ask me. and if it's so good, how come no one knows any numbers? sounds over cracked up if you ask me.
I'm just tryign to ttake the middle man out of the picture. if i could only find someone that makes the stuff that CB sells...because we all *KNOW* CB doesn't make this stuff themselves, they just order and resell....
anyways, 8ft sections of 9" pieces works out to be $25 for each section. about $3.16 a foot, 1/2 the price and the same R, if not a bit more.. This is, also, according to a CB dealer, the sleeve is 13" wide. If someone could post me some accurate information about the sleeve diameter, that would be highly appreciated. I'd hate to order 200Ft cut of this and end up i need to shave 1/2" off it.....
