Three major federal energy conservation programs give considerable emphasis to the installation of thermal insulation material in residences. Questions have been raised as to the availability, effectiveness, and safety of insulation material installed in homes. An evaluation of these problems and the actions taken by federal agencies to alleviate them was made.
In 1977 a shortage of fiberglass insulation, the primary insulation material used to retrofit homes, occurred because of increased demand. While this shortage was alleviated by substituting cellulose insulation, there may be another insulation shortage in early 1980. The shortage has been predicted because demand is expected to increase again, yet fiberglass and boric acid, new safety requirements in cellulose, are not expected to be on production until mid- to late 1980. Improper installation of insulation results in lower thermal resistancy and potential safety hazards, including fires, structural corrosion, and the release of noxious fumes. The Department of Energy (DOE) has taken action to alleviate these problems by proposing various installation and inspection standards under its Residential Conservation Service Program. However, there are several provisions which should be strengthened or amended. Various federal agencies have also proposed labeling requirements and acccompanying tests, but they have not suggested a way to certify laboratory competence.
