UPDATED 11/8/2011: Guardian Building Products has apologized to Allison Bailes. See full information at the end of the article.
On October 19, 2011, blogger Allison Bailes, a frequent contributor to GBA, posted a blog on his Energy Vanguard website about the difficulty of installing fiberglass batts well. You can read his excellent blog here: A Visual Guide to Why Fiberglass Batt Insulation Underperforms.
Bailes wrote that fiberglass batts “get a Grade III in the typical installation. That’s because it’s so difficult to install them well.” Bailes’s statement is indisputable, and hundreds of HERS raters around the country could be called on to back Bailes up. In a July 2009 blog, I wrote almost the same thing.
But the lawyers at Guardian Fiberglass didn’t like what they read. (If you looked closely at Bailes’s photos, you could see that the batts in the photos happened to be manufactured by Guardian.)

In a letter written to Bailes on October 21, Michael Metz, a Guardian lawyer, informed Bailes that “Guardian disagrees with [the] assertion that it is difficult to install fiberglass insulation well. … It is Guardian’s position that these comments by your company together with the picture of Guardian’s products constitute libel, slander, and commercial disparagement. … Guardian demands a response to this letter within ten days with regard to (i) Energy Vanguard’s agreement to cease its negative advertising, and (ii) evidence of Energy Vanguard’s statements and their sources. Guardian will aggressively pursue its remedies to the fullest…
