Cellulose Acetate — Insulation R Values
5.27 lb/ft³, 93.3 F, 0.402 W/mK
Cellulose Acetate (slab) thermal insulation performance data. Two slabs stacked either side, white cellulose acetate fibers parallel to heat flow. Tabulates tested across 1 mean temperatures from 93.3 to 93.3°F. Performance: thermal conductivity 0.402 to 0.402 W/m·K; R-value per inch 0.358 to 0.358 ft²·°F·hr/BTU/in.
