100% Insulated Superstructure
Sandwiched between the exterior waterproofing membrane and the reinforced concrete shell, a continuous layer of polyurethane foam insulates the entire shell structure from extreme temperature fluctuations, preventing structural fatigue and long-term damage. The continuous layer of insulation keeps the product dry by eliminating condensation problems.
In traditional structures, temperature fluctuations cause damaging cyclical thermal stresses that have proven to fatigue and destroy conventional concrete and steel silos over time. In contrast, the outer continuous polyurethane foam insulation in a dome structure, in combination with the inner concrete layer, provides an insulated thermal mass that minimizes temperature fluctuations in the structure. The insulation also minimizes internal condensation and vapor drive from moisture found in some stored products. The result is a longer-lasting structure with elimination of internal and external moisture problems.
