R-1.5 HP Panel
R-1.5 HP is a 1/2’’ 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-1.5 HP 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. It provides greater strength thanks to its higher density.
