Harrison Contracts provide expert assistance to upgrade ductwork to protect air handling and other types of ductwork against fire for up to 2 hours.
We can protect horizontal and vertical ductwork, as well as ducts passing through walls and floors without dampers to Type A, Type B or kitchen extract ducts (grease ducts).
Our engineers and contract managers work in partnership with our customers to identify the most cost effective and appropriate materials for meeting the requirements of each project.
