Hood Moulds: The Functional Art of Architectural Rain Protection
In the world of traditional architecture, beauty often arises from necessity. One such example is the hood mould—a specialized external projection designed to protect a building's openings from the elements. While it may appear to be a purely decorative trim, its primary purpose is practical: to divert rainwater away from windows and doors to prevent moisture damage to the wall.
Depending on the region or the specific architectural style, this feature is known by several names, including a drip mould, dripstone, or label mould (derived from the Latin word labia, meaning "lip").
[ไม่มีภาพประกอบ]The Evolution of the Hood Mould
The use of these projections evolved alongside the major architectural movements of Europe. While they were first introduced during the Romanesque period, they reached their peak of popularity and complexity during the Gothic period. During this era, they were frequently designed in the form of a pediment—a triangular gable found over an opening.
As architectural trends shifted toward domestic settings and the use of rectangular windows became more common, hood moulds transitioned from grand cathedrals and castles into residential architecture, where they continued to serve both a protective and aesthetic role.
Anatomy and Design
A hood mould is essentially a moulded strip of stone or masonry that projects from the wall surface. By creating a physical barrier, it forces rainwater to "drip" off the edge rather than running down the face of the opening.
The Label Stop
The ends of a label mould are often finished with a specific decorative element known as a label stop. These ornaments mark the termination of the moulding and can range from simple geometric shapes to intricate carvings, adding a final touch of artistry to the functional structure.

Frequently Asked Questions
What is the main purpose of a hood mould?
The main purpose is to act as an external projection that throws rainwater away from an opening in a wall, protecting the structure from water ingress.
What is the difference between a hood mould and a label mould?
There is no functional difference; they are different names for the same architectural feature, with "label mould" deriving from the Latin word for lip.
When did hood moulds become common in architecture?
They were introduced during the Romanesque period but became significantly more common during the Gothic period.
What is a label stop?
A label stop is the ornamentation used to terminate the sides of a label mould.
How did the use of hood moulds change in domestic architecture?
As rectangular windows became more prevalent in homes, hood moulds became more common in domestic building designs.
