“
In construction, a “”top hat”” typically refers to a type of roofing or construction element used to create a raised portion on a roof or to add extra height to an existing structure. It is often made of metal and resembles the shape of a top hat, which is a tall, cylindrical hat with a flat top and a wide brim.
The use of top hats in construction can serve various purposes, including:
Roofing: In roofing applications, a top hat is used to create a raised portion on the roof. This may be done for aesthetic reasons or to accommodate certain features like skylights, vents, or mechanical equipment.
Building extensions: When adding an extension to an existing building, top hats can be used to increase the height of the walls, allowing for a seamless connection between the old and new portions of the structure.
Roof insulation: In some cases, top hats can be used to create a void between the roof cladding and the insulation layer. This space helps improve thermal insulation and energy efficiency within the building.
Architectural design: Top hats can also be used for architectural purposes to create unique shapes or features on the exterior of a building, providing a distinctive look.
It’s worth noting that the term “”top hat”” may not be universally used in all regions or construction industries. Different areas may have different names or terminologies for similar construction elements or techniques.”
