Buildings of all ages can experience damage due to water penetration into walls through joints and around windows. This unwanted moisture can cause freeze thaw issues, finish material degradation, and mold propagation. If the internal atmospheric humidity of a wall is increased by 5%, it can lower insulating R-Values by as much as 50%. Willseal products are designed to allow condensation and moisture to escape.
