Crestings and finials are decorative elements commonly found in conservatories and serve both functional and aesthetic purposes. Crestings are winding ridges or elevated patterns typically added at the height of a conservatory roof to create a beautiful finish and a practical feature to keep rainfall out of the building. On the other hand, finials, which come in various forms and sizes and are beautiful structures that sit atop the crestings, bring a touch of refinement to the conservatory’s architecture. In addition to their aesthetic value, they can also be used to help regulate the temperature within the greenhouse by allowing for the release of hot air that can accumulate at the top of the structure.
