      Why Tri‑Ply® Ply 4?

      High tensile strength and a high degree of dimensional stability results in a roof system with greater resistance to splitting and cracking. Optimum porosity of the felt provides ready escape of air while allowing proper asphalt penetration at the time of mopping, and the asphalt coating provides a high degree of moisture resistance.
