With pressure treated lumber mandated by the EPA to be arsenic-free, the lumber industry had to develop safer, non-toxic alternative treatments like ACQ. But
this important change has called attention to the fact that the aluminum flashing typically sold with pressure treated wood simply is not compatible with the high copper content of the treated woods designed for ground contact, which are mandatory as of 1/1/18.

The solution is YorkShield 106PTTM copper flashing, which offers superior performance, more flexibility, lighter weight, better looks, longer life, & competitive prices. In other words, it’s got aluminum flashing products beat in every possible way.Metal flashing that offers best in class puncture and tear resistance. It can be applied from 20°F to 170°F and stays stable and air tight from -70°F to 250°F. Now considered the best self-adhering through-wall flashing. The flexible sheet of 2 mil type 304 is compatible with all neighboring materials and the 10 mils of butyl provides superior adhesion outperforming traditional peel and stick.
