What's up guys? I'm in the midst of installing a New Yorker boiler in a shed behind my house. After having trouble locating any insulation companies who wanted to be bothered with helping me insulate my pex lines underground, I decided to tackle it myself. I dug the trench and constructed an 8" X 8" ID chase out of the pink insulation board, and centered my pex lines in it with wire hangers. I purchased the 600 board foot Tiger Foam rapid-rising insulation kit to foam the lines in place myself. I followed their directions to the letter, and had optimum temperature conditions. The kit worked great, no complaints there, but ran out after 70 feet, which according to my calculations is about 1/3 less than what it was advertised to contain. It was (just) enough to complete my job, but I was expecting quite a bit left over for another insulating project. I'm now in the middle of trying to get some kind of resolution from Tiger Foam, I just wanted to give everyone a little heads up about their product. It may have been a fluke, but I'd be careful because in the average insulation project it would be hard to figure out exactly how much foam actually came out of their kit, therefore, hard to know if you were shorted.
