Thermal Expansion

While the concept of thermal expansion is well understood among architects and engineers, occasionally there are problems relating to insufficient thermal expansion allowances.

Thermal Conductivity

Thermal conductivity of architectural metals used to clad the exteriors of buildings is a significant factor in energy efficiency. The purpose of insulating materials is to limit the transfer of heat in or out of the structures, so as to maintain a comfortable temperature at a reasonable cost.

Flatness of Sheet Metal

Metal flatness is a big issue in architectural panel work. If the incoming material has errant shape, the panel manufacturer or fabricator cannot avoid producing a panel that exhibits oil canning (repeating undulations in the panel surface), concave or convex profiles or that buckles at the corners.
