BP R-1.3/R-1.5 Insul-Sheathing Panels

R-1.3 is a 7/16’’ wall sheathing panel produced from non-toxic organic materials and natural wood fibers. 

All panels are asphalt coated on both sides for greater weather resistance. 

R-1.3 has excellent water vapor permeance which allows interior water vapor to escape to the exterior and not be trapped within the wall cavity where it could cause damage.

R-1.5 is a 1/2’’ wall sheathing panel produced from non-toxic organic materials and natural wood fibers. 

All panels are asphalt coated on both sides for greater weather resistance.

R-1.5 has excellent water vapor permeance which allows interior water vapor to escape to the exterior and not be trapped within the wall cavity where it could cause damage.
