Cast iron fascias and inserts were a fixture in homes of the traditional architectural periods such as Victorian, Federation & Edwardian and distinguished by their period specific decorative features .Cast iron's ability to tolerate very high heat exposure enables it to provide a stable and non-combustible zone immediately around the open fireplace or gas heater .Inserts are still a popular choice in new and renovated homes built in the classic styles where decorative gas coal burners are usually fitted to recreate the original live fire effect.
