The effect of compression on the material R-value of fiberglass batt insulation

Conference ·
OSTI ID:6488917
Fiberglass batt insulations intended for use in buildings are labeled with an R-value and thickness at which the R-value is achieved. In some cases the insulation is installed in such a way that the label thickness is not achieved. The material R-value of fiberglass batts installed at less than full thickness will be less than the full-thickness R-value. Results are presented for values measured in accordance with ASTM C 518 for commercially available fiberglass batts at full thickness and compressed to as much as 50% of full thickness. Thermal data and the resulting correlations are presented in this paper for six products manufactured in 1990. 4 refs., 6 tabs., 8 figs.
