In a recent Energy Vanguard blog, Allison Bailes reviews a study by the Home Innovation Research Labs (HIRI) that surveys homebuilder practices. The study shows that fiberglass is still the dominant insulation material, accounting for 71% of all the insulation used by the 1,600 builders surveyed.
Despite its popularity as an insulating material, Allison points out, “there’s really only one problem with fiberglass: poor installation.” It’s a valid point, at least for batt insulation (by far the most used version) and Allison does an excellent job summarizing the problems and myths of fiberglass in this article. For anyone who uses fiberglass batts, it’s a must read, at least for the new hires.
