PLYGOOD R2 Sheathing

PLYGOOD R2 Sheathing header

On walls fully sheathed with structural sheathing, use GreenGuard PLYGOOD R2 Sheathing over the structural sheathing to meet the R13+5h prescriptive requirements of the 2009 Energy Code in Zones 5, 6 and Marine 4. Continuous Insulation (Ci) means creating an insulation blanket around the exterior of the structure.  When you apply PLYGOOD R2 Sheathing over structural sheathing you you create a wall with reduced energy loss through thermal bridging and reduced potential for water penetration from the exterior.  With insulation on the exterior of the wall cavity, the dew point is moved outward, reducing the potential for condensation on the warm side of the wall cavity.
PLYGOOD R2 Sheathing is 7/16 in. thick and available in board sizes of 4 ft. x 8 ft. and 4 ft. x 9ft.
