Coordinated flashing systems that integrate with other exterior wall products, such as weather-resistant barriers and air barriers, can prove to simplify installation, reduce the chance for construction defects, and mitigate the professional risk to everyone involved. While there are different material and product choices, the goal is the same for all, namely to create a cost-effective and long-lasting solution for properly and effectively sealing above, below, and around the sides of window and door openings.
