In commercial construction projects in Australia, a drip moulding (also known as a drip edge or drip cap) is an architectural feature designed to direct water away from the structure to prevent water damage. It is typically installed at the edges of roofs, windows, doors, and other exterior elements to ensure that rainwater or condensation does not seep into the building materials, which could lead to deterioration, mold growth, or structural issues.

Drip mouldings are usually made from durable materials such as metal (aluminium, steel), PVC, or other weather-resistant materials. They are shaped to create a small overhang or lip that channels water away from the surface it is protecting. This overhang ensures that water drips off the edge rather than running down the face of the building or into joints and seams.

Materials Used for Drip Moulding

Drip mouldings can be made from a variety of materials, including:

• Stone
• Brick
• Wood
• Metal

Purpose of Drip Moulding

The primary purposes of drip moulding are:
