Louvre & damper

A louvre is a set of angled slats — usually aluminium — that let air pass while blocking rain, direct sun and sightlines. In Dubai you see them screening rooftop AC and chiller plant, plant-room and generator openings, car-park ventilation and AC condenser enclosures. They matter because equipment has to breathe: a condenser or plant room boxed in behind an undersized or clogged louvre recirculates its own hot air and overheats, so the free area, the blade design and a clean powder-coated or marine-grade finish (for coastal salt) all count. A damper, by contrast, is a moving blade inside the ductwork that controls or stops airflow — *volume* dampers balance how much air each room gets, *fire* dampers slam shut to stop fire and smoke spreading through ducts. The two get confused because both regulate air, but a louvre is the fixed architectural screen on the outside and a damper is the controllable blade on the inside. Get either wrong — a blocked louvre starving a condenser, or a stuck damper leaving a room starved or noisy — and comfort and equipment life both suffer. Specifying and maintaining external louvre screens is metalwork for Al Ghubaiba's aluminium and facade team, while the duct dampers sit with the AC and extraction side.
