Skydome manufactures the Powervent, a ventilation product used to effectively remove hot air from roof cavities. Unlike traditional wind powered vents, the Powervent doesn't require a breeze to function, but operates thermostatically or on a timer switch.

It is able to expel 15,000L of air per minute, equivalent to eight wind vents operating at maximum capacity and costs less than one cent an hour to run.

Effective ventilation of a building's roof cavity is the best way to combat heat getting trapped in the roof space, which can result in joint distortion, sagging ceilings and paint problems.

Good ventilation can also improve the energy efficiency of air conditioners and the performance of roof insulation.
