An exterior insulating sheathing which comprises a foam polystyrene ply and a second ply glued to said polystyrene ply throughout. The second ply is preferably a fiberboard but may also be a waferboard. The sheathing is nailable, has a racking load of about 1900 to 3700 lbs, and has at least he exposed side of the second ply water resistant. This sheathing has a minimum tensile strength of 65+/-14 kPa, a linear expansion at 97% RH and 23 DEG C., of less than 0.40%+/-0.02, a water vapor transmission of at least 96ng.Pa.s.m2, and a modulus of rupture of 0.5 to 17.2 megaPascal.
