Our Services
We manufacture non-coated fire rated ductwork that has been tested to both BS standards and EN standards.
We will work with you every step of the way, including inducting your installers in the installation of the product, and if required we can certify the installation at the end of the install.
Along with the ductwork we provide bespoke support systems and will always be available to answer any questions that may arise.
