The Group > Ashway As a specialist ductwork fabrication company, Ashway often works closely with Calibre Ventilation on their design/install projects and can produce one-off solutions on a rapid turnaround where site requirements often change during the install process. Ashway's site teams also work with Klima-Therm to position, assemble and pressure test their range of Saiver Air Handling Units. This ensures the product is correctly assembled within the time constraints of the project and to the client's satisfaction. Please contact us for more information.
