Polyurethane foam-insulation application

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

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.
