Role of Flashing in Building Facades Metal flashing is an essential component of any properly designed exterior cladding system.
Its primary functions include: Protecting vulnerable areas of the façade from water penetration Providing structural and visual transitions between siding panels Covering exposed edges for a clean architectural finish Improving the durability and weather resistance of the building envelope Well-designed flashing not only protects the building but also contributes significantly to the overall visual quality of the façade, creating sharp lines, defined edges, and a refined architectural appearance. With TerraShield flashing systems, builders and designers can achieve both functional protection and professional architectural detailing in modern metal siding applications
