The Liberty Split Ring System has been developed to satisfy both the
engineers need for performance, durability, ease of maintenance and ever increasing
specification demands and the designers dream of having the flexibility to be able to
develop a purpose built lantern that is ideal for a projects purpose rather than
being a compromise on that ideal. All this and not having to pay through the nose for it.
Our engineers worked on the principal that if you have a strong foundation you can build
anything on top. The Split ring foundation can accommodate, within reason, any style of
upper body from hemispheres to pyramids and numerous glazing options from flat glass to
hemispherical. The systems simplicity makes it extremely easy to work with, install
and maintain.
