Manoeuvring large military vehicles into or out of a service hanger will always leave dangerous heavy diesel fumes lingering in the air. General (High Level) Ventilation will quietly extract exhaust/smoke from within the building, ensuring a cleaner and healthier workplace.
This advanced and innovative pre-insulated ductwork system eliminates virtually all the disadvantages associated with galvanised sheet steel lagged with mineral fibre.
The rigid thermoset insulated core is faced with either silver aluminium foil on both sides, or silver aluminium foil on one side and black coated aluminium foil on the other. Weighing in at 75% less and with an air-leakage rate at a fraction of conventional galvanised sheet steel ductwork, makes this an ideal and cost-effective solution.
