plastic fiber insulation
The R-values of plastic fiber insulation vary with batt density: R-3.8 per inch at 1.0 lb./ft3 density to R-4.3 per inch at 3.0 lb/ft3 density.
Plastic fiber insulation is relatively non-irritating to work with, but the batts reportedly can be difficult to handle and cut with standard tools.
