This article is only available to GBA Prime Memberscenter_img Back in 2010, I wrote an article condemning certain deceptive sales practices by Icynene, a spray foam manufacturer. In that article, I discussed inaccuracies in a letter written and signed by Viktor Ginic, an engineer who was then employed by Icynene. Ginic wrote, “Based on measured air infiltration and the number of energy analyses performed, we have found that Icynene, installed in accordance with the manufacturer’s installation instructions to a nominal thickness of 3″ in the walls and floors and 6″ in roof/ceiling applications, will perform better thermally than R-19 and R-38 air-permeable mineral fiber insulation.”Back in 2010, all Icynene spray foam was open-cell spray foam. Since 3 inches of open-cell Icynene has an R-value of R-11, it’s simply untrue that it performs better than R-19 mineral fiber insulation. Nor will 6 inches of open-cell Icynene (R-22) perform as well as R-38 mineral fiber insulation.Needless to say, Icynene was unhappy to have a spotlight shone on their letter. (My article garnered 311 comments, and is still published on the GBA site.)Unfortunately, deceptive letters like the one distributed by Icynene are still being circulated by unscrupulous spray foam contractors. In late February, another example of these “Hall of Shame” letters was shared by a GBA reader named Russell Miller.Two of these deceptive letters are posted on the web site of a spray foam contractor, J. Anderson Insulation of Belleville, Illinois. The letterhead on the letters reads “EnergyWise, 1303 Lee Street, McKinney, Texas 75069.” EnergyWise is still in business, although its current address is 1111 West Mockingbird Lane, Suite 1345, Dallas, Texas  75247.The letters aren’t recent. They are dated May 3, 2011, and signed by Richard L. Rue and Michael R. Busby, PhD. Because the letters focus on the performance of spray foam manufactured by Lapolla, a spray foam manufacturer with headquarters in Texas, it’s reasonable… last_img
