R-1.3 is a 7/16’’ wall sheathing panel produced from non-toxic organic materials and natural wood fibres. All panels are asphalt coated on both sides for greater weather resistance. R-1.3 has excellent water vapour permeance which allows interior water vapour to escape to the exterior and not be trapped within the wall cavity where it could cause damage.
