The groin vault is a ceiling of many names. It is often called a groined vault and sometimes even known as a cross vault because it is made by intersecting two barrel vaults. It is the edge between these intersecting barrel vaults that creates the unique look that only groin vaults can offer. And in fact, this edge is where the ceiling gets its name (this is the groin of the vault). Just browse our photo gallery below for inspiration. Have you already installed one of our groin vaults?
