With many older homes, poor insulation means that artificial heating and cooling are a necessity and even in modern homes people often tend to turn on the air when they could just as easily open a window or skylight.
Acccording to Velux, the best way to bring fresh air into a home is with an openable skylight which, because it sits on the roof, catches more breeze than a vertical benefit and, at the same time, provides natural daylight.
Electric remote controlled skylights feature rain sensors that will close the skylight when the weather turns bad and double glazing keeps the indoors comfortable even in the extremes of summer.
