Thru-Wall

TAMKO TW Thru-Wall Flashing

Flashings remain a critical component of any cavity wall system.

TAMKO’s Thru-Wall flashing protects specific areas within exterior wall assemblies and creates a barrier for water to follow to the face of the exterior finish.

TAMKO® Thru-Wall helps avoid costly degradation of wall components.
