See urea-formaldehyde binder and methyl diisocyanate (MDI) binder. ; and small percentages of clay, paraffin, and carbon black that provide moisture resistance. These ½" sheathing products cut with a knife and have good sound dampening, an R-valueMeasure of resistance to heat flow; the higher the R-value, the lower the heat loss. The inverse of U-factor. of 1.3 (per ½"), and a perm rating of 23, according to the company. This high permeability is an important feature in climates where wall-cavity drying to the exterior is important.
