Buildings rely on multiple protective layers to remain dry, stable and energy efficient over time. Two terms that are often confused are cladding and sarking, yet they perform very different functions within construction. Understanding these distinctions is useful for homeowners, contractors and those exploring builders merchants jobs.
Understanding the Purpose of Cladding
Cladding refers to the outermost material fixed to the exterior of a building. It creates the visible finish while protecting the structure from weather exposure. Materials commonly used include timber, fibre cement, metal panels and brick veneer. Beyond appearance, cladding contributes to durability and can improve thermal performance when combined with insulation.
Where Cladding Is Typically Installed
Cladding is applied to external walls across residential, commercial and industrial buildings. It provides architectural character while forming a barrier against wind and rain. In modern construction, cladding systems vary widely, making product knowledge valuable for those considering builders merchants jobs in customer facing roles.

What Sarking Does Within a Building
Sarking is an internal protective layer installed beneath roof coverings or behind wall systems. It is usually a membrane or board designed to control moisture, airflow and heat transfer. Sarking is not visible once construction is complete, yet it plays a vital role in weather tightness and comfort.
Key Differences Between Sarking and Cladding
Cladding is external, visible and focused on protection and appearance. Sarking is concealed and supports internal performance by managing environmental conditions. Together they form a layered system.
