Structure with insulation and ventilators

This structure was supplied with insulation and ventilators. Both are options rather than standard, and both address the same problem: a sheeted roof in the South African sun turns the space underneath into an oven.

Bubble foil insulation cuts radiant heat coming through the sheeting and controls condensation on the underside. Ventilators, static or turbine, move the hot air that collects at the ridge out of the building. Anywhere people work all day, or anywhere stock is heat-sensitive, they earn their cost.
