Why is it important for cladding to be weather-resistant?

Cladding serves as a protective layer for the building enclosure, and its weather-resistant qualities are crucial in preventing moisture intrusion and other weather-related issues. When cladding effectively keeps out water, it protects the structural elements of a building from potential deterioration caused by rot, mold, and corrosion. This preservation of the building envelope is essential for maintaining the overall integrity and longevity of the structure, ensuring that it can withstand various environmental conditions over time.

By preventing deterioration, weather-resistant cladding also contributes significantly to the building's thermal efficiency and energy performance, as moisture damage can lead to increased energy costs and reduced comfort levels within the building. Protecting the underlying materials from the elements is, therefore, a primary reason for emphasizing weather resistance in cladding materials.
