Lengthened structural life, plus comfortable conditions
With the airform inflated, polyurethane foam insulation is applied inside, forming a layer two to three inches thick. This layer acts as a continuous and uninterrupted thermal barrier between the exterior and interior of the dome, an important element to keeping temperatures consistent within the structure.
Polyurethane foam is applied to the air-supported PVC airform. Reinforcing and concrete are then placed against the foam insulation.Upon completion of construction, the foam acts as a thermal insulator, protecting both the concrete dome structure and the product stored inside.
